I have a map with a source xml standard xml file and destination file which needs to be a flat file.
I've found an article to assist with the conversion to string, the issue I am having now is that the output is not valid against the destination schema and I believe I need to escape the characters to get around this. I'm looking for some help with the XSLT for that.
Source file
<request>

I am quite a newbie to XSLT and I need to figure out how to retrieve repeating elements from a XML file in a specific order based on their attribute value to a CSV file. My result document is a CSV file that I ultimately need to import its content to SQL Server tables. Therefore, the order of the retrieved elements within the CSV file does matter as they need to match the table columns defined as headers.
My problem occurs with the Project Content_Detail element that exists in different languages and can appear in any order in the XML source. I only need to extract the German version with the Title, Goal element first, followed by the English version elements.
I use SSIS with MS Visual Studio 2019 to transform my XML to a CSV file. MS Visual Studio supports only XSLT 1.0.
Here is my XML file (EDITED):
<?xml version="1.0" encoding="utf-8"?>
<dta:Projects xmlns:dta="http://domain.test/dta">
<dta:Project>
<dta:Core-Basis>
<dta:Goal>1672</dta:Goal>
</dta:Core-Basis>
<dta:Basisinfo>
<dta:Content>
<dta:Content_Detail Lang="de">
<dta:Title>Wirtschaft</dta:Title>
<dta:Aim>Steigerung</dta:Aim>
</dta:Content_Detail>
<dta:Content_Detail Lang="en">
<dta:Title>Economy</dta:Title>
</dta:Content_Detail>
</dta:Content>
</dta:Basisinfo>
</dta:Project>
<dta:Project >
<dta:Core-Basis>
<dta:Goal>2035</dta:Goal>
</dta:Core-Basis>
<dta:Basisinfo>
<dta:Content>
<dta:Content_Detail Lang="en">
<dta:Title>Environmental Protection</dta:Title>
<dta:Aim>Facilitation</dta:Aim>
</dta:Content_Detail>
<dta:Content_Detail Lang="de">
<dta:Title>Naturschutz</dta:Title>
</dta:Content_Detail>
</dta:Content>
</dta:Basisinfo>
</dta:Project >
</dta:Projects>
This is my XSLT file (EDITED). I tried to add numerous order and sort arguments to the xsl:if block but I couldn’t come up with a working solution yet:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:dta="http://domain.test/dta" exclude-result-prefixes="dta">
<xsl:output method="text" encoding="UTF-8" indent="no"/>
<xsl:template match="/">
<xsl:text>DTA_Goal;DTA_Title_de;DTA_Aim_de;DTA_Title_en;DTA_Aim_en;
</xsl:text>
<xsl:apply-templates mode="find_content"/>
</xsl:template>
<xsl:template match="text()|#*" mode="find_content"/>
<xsl:template match="dta:Project" mode="find_content">
<xsl:value-of select="concat(dta:Core-Basis/dta:Goal,';')"/>
<xsl:apply-templates mode="find_content"/>
</xsl:template>
<xsl:template match="dta:Content_Detail" mode="find_content">
<xsl:if test="#Lang='de'">
<xsl:value-of select="concat(dta:Title,';')"/>
<xsl:value-of select="concat(dta:Aim,';')"/>
</xsl:if>
<xsl:if test="#Lang='en'">
<xsl:value-of select="concat(dta:Title,';')"/>
<xsl:value-of select="concat(dta:Aim,'
')"/>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
This is my CSV output so far, not sorting the Content_detail based on their language value attribute:
DTA_Goal;DTA_Title_de;DTA_Aim_de;DTA_Title_en;DTA_Aim_en;
1672;Wirtschaft;Steigerung;Economy;
2035;Environmental Protection;Facilitation
Naturschutz;;
This is what I need:
DTA_Goal; DTA_Title_de; DTA_Aim_de; DTA_Title_en; DTA_Aim_en;
1672;Wirtschaft;Steigerung;Economy;;
2035;Naturschutz;;Environmental Protection;Facilitation;
As I am not a professional programmer, any help or comment also on the rest of my code is highly appreciated.
In your input, one of the dta:Project elements has a dta:Core-Basis child, while the other has dta:Core-Basisdaten. Assuming that's a mistake*, you could produce the needed output simply by:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:dta="http://domain.test/dta">
<xsl:output method="text" encoding="UTF-8" />
<xsl:template match="/dta:Projects">
<!-- header -->
<xsl:text>DTA_Goal;DTA_Title_de;DTA_Aim_de;DTA_Title_en;DTA_Aim_en;
</xsl:text>
<!-- data -->
<xsl:for-each select="dta:Project">
<xsl:value-of select="dta:Core-Basis/dta:Goal"/>
<xsl:text>;</xsl:text>
<!-- de -->
<xsl:variable name="content-de" select="dta:Basisinfo/dta:Content/dta:Content_Detail[#Lang='de']" />
<xsl:value-of select="$content-de/dta:Title"/>
<xsl:text>;</xsl:text>
<xsl:value-of select="$content-de/dta:Aim"/>
<xsl:text>;</xsl:text>
<!-- en -->
<xsl:variable name="content-en" select="dta:Basisinfo/dta:Content/dta:Content_Detail[#Lang='en']" />
<xsl:value-of select="$content-en/dta:Title"/>
<xsl:text>;</xsl:text>
<xsl:value-of select="$content-en/dta:Aim"/>
<xsl:text>;</xsl:text>
<xsl:text>
</xsl:text>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
(*) If not, change:
<xsl:value-of select="dta:Core-Basis/dta:Goal"/>
to:
<xsl:value-of select="(dta:Core-Basis|dta:Core-Basisdaten)/dta:Goal"/>
P.S. Not sure why you need the trailing ; at the end of each line.
Background info. I'm writing an XSL file to take an XML sent to the server by an analytical instrument and translate that file into an XML file accepted by our LIMS system.
Here is a Simple XML file coming from the instrument:
<dataRoot>
<dataRow>
<a0>2020-05-29 10:48:09 UTC-4</a0>
<a1>MSA - Conc.(Bench)</a1>
<a2>WHC202005270038</a2>
<a3>00251832</a3>
<a4>1.15966</a4>
<a5>MSA</a5>
<a6>101.067</a6>
</dataRow>
</dataRoot>
Here is what I have so far for the XSL File:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0"/>
<xsl:template match="/dataRoot">
<INBOUND>
<xsl:call-template name="A"/>
<xsl:copy-of select="A" />
</INBOUND>
</xsl:template>
<xsl:template match="/dataRow" name="A">
<xsl:for-each select="dataRow">
<xsl:variable name="sSampleID" select="normalize-space(a2)" />
<xsl:variable name="sSubmitter">AutoT_EQ00004</xsl:variable>
<xsl:variable name="sEnteredBy">EQ00004</xsl:variable>
<!-- Use a variable for OWNER, so that only one spot needs changing if a different value is desired -->
<xsl:variable name="sOwner">WHC</xsl:variable>
<xsl:variable name="sParameter" select="normalize-space(a5)" />
<xsl:variable name="sParamName"> <!-- Parameter names mapping for import to LIMS-->
<xsl:call-template name="ConvertPaName">
<xsl:with-param name="sPaName" select="$sParameter" />
</xsl:call-template>
</xsl:variable>
<xsl:variable name="sResult" select="normalize-space(a6)" />
<xsl:for-each select="$sParamName">
<INBOX_SAMPLE>
<EVENT>1</EVENT>
<SAMPLE_ID><xsl:value-of select="$sSampleID"/></SAMPLE_ID>
<SUBMITTER><xsl:value-of select="$sSubmitter" /></SUBMITTER>
<ENTERED_BY><xsl:value-of select="$sEnteredBy" /></ENTERED_BY>
<OWNER><xsl:value-of select="$sOwner" /></OWNER>
<PARAMETER_NAME><xsl:value-of select="$sParamName"/></PARAMETER_NAME>
<SRESULT><xsl:value-of select="$sResult"/></SRESULT>
</INBOX_SAMPLE>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
<!-- Convert PaNames as needed, and skip processing certain values that are not actual Parameters (ie: 'Application') -->
<xsl:template name="ConvertPaName">
<xsl:param name="sPaName" />
<xsl:choose>
<xsl:when test="$sPaName='MSA'">MSA - Conc.(Bench)</xsl:when>
<xsl:when test="$sPaName='MSA'">Free MSA</xsl:when>
<xsl:otherwise>Halt_Import</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
Here is the output of current translation:
<INBOUND>
<INBOX_SAMPLE>
<EVENT>1</EVENT>
<SAMPLE_ID>WHC202005270038</SAMPLE_ID>
<SUBMITTER>AutoT_EQ00004</SUBMITTER>
<ENTERED_BY>EQ00004</ENTERED_BY>
<OWNER>WHC</OWNER>
<PARAMETER_NAME>MSA - Conc.(Bench)</PARAMETER_NAME>
<SRESULT>101.067</SRESULT>
</INBOX_SAMPLE>
</INBOUND>
What I need to do is to duplicate this node for both parameter names:
<xsl:when test="$sPaName='MSA'">MSA - Conc.(Bench)</xsl:when>
<xsl:when test="$sPaName='MSA'">Free MSA</xsl:when>
So that my output becomes:
<INBOUND>
<INBOX_SAMPLE>
<EVENT>1</EVENT>
<SAMPLE_ID>WHC202005270038</SAMPLE_ID>
<SUBMITTER>AutoT_EQ00004</SUBMITTER>
<ENTERED_BY>EQ00004</ENTERED_BY>
<OWNER>WHC</OWNER>
<PARAMETER_NAME>MSA - Conc.(Bench)</PARAMETER_NAME>
<SRESULT>101.067</SRESULT>
</INBOX_SAMPLE>
<INBOX_SAMPLE>
<EVENT>1</EVENT>
<SAMPLE_ID>WHC202005270038</SAMPLE_ID>
<SUBMITTER>AutoT_EQ00004</SUBMITTER>
<ENTERED_BY>EQ00004</ENTERED_BY>
<OWNER>WHC</OWNER>
<PARAMETER_NAME>Free MSA</PARAMETER_NAME>
<SRESULT>101.067</SRESULT>
</INBOX_SAMPLE>
</INBOUND>
This is because instrument sends one parameter name like "MSA" but in our LIMS we have it under either "Free MSA" or "MSA - Conc.(Bench)" and I need to be able to provide the result for both possible parameter names and LIMS will insert the one that it find a match for.
Thank you so much in advanced :)
Add parm elements to template.
<xsl:template name="ConvertPaName">
<xsl:param name="sPaName" />
<xsl:choose>
<xsl:when test="$sPaName='MSA'">
<parm>MSA - Conc.(Bench)</parm>
<parm>Free MSA</parm>
</xsl:when>
<xsl:otherwise>
<parm>Halt_Import</parm>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
Call your template
<xsl:variable name="sParamName">
<xsl:call-template name="ConvertPaName">
<xsl:with-param name="sPaName" select="$sParameter" />
</xsl:call-template>
</xsl:variable>
Convert to node set: (However you do it. You currently don't have the msxml namespace set up.)
<xsl:variable name="sParamNameList" select="msxml:node-set($sParamName)">
Then use the parm list in your for-each loop.
<xsl:for-each select="$sParamNameList/parm">
I've got data in XML that has some header information then a series of items. I'm using XSLT to translate that into a different format, also with a header area and a series of items.
However in the post translation result, I want one piece of data only found in the header to be included in every instance of the items, even though it will simply be repeating the same value. (this value may change so I cannot hard code it)
Sample data (significantly simplified)
<rss>
<channel>
<title>Playlist One</title>
<items>
<item>
<title>Video One</title>
</item>
<item>
<title>Video Two</title>
</item>
<item>
<title>Video Three</title>
</item>
</items>
</channel>
</rss>
My desired result is something like this:
playlist_header_title=Playlist One
playlist_title=Playlist One
video_title=Video One
playlist_title=Playlist One
video_title=Video Two
playlist_title=Playlist One
video_title=Video Three
My XSLT is very complicated (and unfortunately I inherited it from someone else so I'm not sure what everything does, I've self-taught myself online but am in a bit over my head)
Roughly the key pieces look like this:
<xsl:template name="rss" match="/">
<xsl:variable name="playlist_title">
<xsl:value-of select="string(/rss/channel/title)"/>
</xsl:variable>
<xsl:for-each select="rss">
<xsl:apply-templates name="item" select="channel/items/item"/>
</xsl:for-each>
</xsl:template>
Then there's a massive template called "item" that I won't include here, but basically it outputs all the item data as desired, I just can't figure out how to access the "playlist_title".
When I try to call (from inside the template "item")
<xsl:value-of select="string($playlist_title)"/>
it returns a blank. I assume this is because that variable was created outside the for-each loop and so it not available. (it will display the data correctly when I output it before the for-each loop in the result's version of the header, but that doesn't get me far enough)
I've tried using with-param in the apply-templates, and also tried changing it to call-template inside another loop also using with-param, but they also display a blank.
I've also tried sending in a string rather than pulling the playlist_title from the XML just to confirm I am able to pass any value into the template, but they too come out blank.
For instance:
<xsl:for-each select="channel/items/item">
<xsl:call-template name="item">
<xsl:with-param name="playlist_title">blah</xsl:with-param>
</xsl:call-template>
</xsl:for-each>
<xsl:template name="item">
<xsl:param name="playlist_title" />
playlist_title=<xsl:value-of select="string($playlist_title)"/>
video_title=...
...
</xsl:template>
This did not return the value "blah" but just a blank. (my hope was to then replace "blah" with the playlist_title value pulled from the XML, but none of it is getting through)
I'm stumped! Thanks for any help.
In your first example, attempting to reference the $playlist_title inside of your template for item is failing because the variable does not exist inside of that template. It was created inside of the template match for rss and is locally scoped.
If you want to be able to use the $playlist_title in other templates, you need to declare it outside of the rss template in the "global scope".
For instance:
<xsl:variable name="playlist_title">
<xsl:value-of select="string(/rss/channel/title)"/>
</xsl:variable>
<xsl:template name="rss" match="/">
<xsl:for-each select="rss">
<xsl:apply-templates name="item" select="channel/items/item"/>
</xsl:for-each>
</xsl:template>
As for your second attempt, referencing the xsl:param playlist_title, it worked for me. Double-check to ensure that you don't have a type-o or other difference between the name of the parameter that was declared and the name of the parameter that you are referencing.
You might try something like this to achieve your desired output, using an xsl:variable:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" indent="yes"/>
<xsl:variable name="playlist_title" select="/rss/channel/title" />
<xsl:template match="/">
<xsl:apply-templates select="rss/channel"/>
</xsl:template>
<xsl:template match="channel">
<xsl:text>playlist_header_title=</xsl:text>
<xsl:value-of select="title"/>
<xsl:text>
</xsl:text>
<xsl:apply-templates select="items/item"/>
</xsl:template>
<xsl:template match="item">
<xsl:text>playlist_title=</xsl:text>
<xsl:value-of select="$playlist_title"/>
<xsl:text>
</xsl:text>
<xsl:text>video_title=</xsl:text>
<xsl:value-of select="title"/>
<xsl:text>
</xsl:text>
</xsl:template>
</xsl:stylesheet>
Or you can eliminate the xsl:variable and use an xsl:param:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" indent="yes"/>
<xsl:template match="/">
<xsl:apply-templates select="rss/channel"/>
</xsl:template>
<xsl:template match="channel">
<xsl:text>playlist_header_title=</xsl:text>
<xsl:value-of select="title"/>
<xsl:text>
</xsl:text>
<xsl:apply-templates select="items/item">
<xsl:with-param name="playlist_title" select="title"/>
</xsl:apply-templates>
</xsl:template>
<xsl:template match="item">
<xsl:param name="playlist_title" />
<xsl:text>playlist_title=</xsl:text>
<xsl:value-of select="$playlist_title"/>
<xsl:text>
</xsl:text>
<xsl:text>video_title=</xsl:text>
<xsl:value-of select="title"/>
<xsl:text>
</xsl:text>
</xsl:template>
</xsl:stylesheet>
I've been looking for a method to strip my XML content of apostrophes (') since my DBMS is complaining of receiving those.
I need
<name> Jim O'Connor</name>
to become:
<name> Jim O''Connor</name>
By looking at the example described here, that is supposed to replace ' with '', I constructed the following script:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes" />
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*" />
</xsl:copy>
</xsl:template>
<xsl:template name="sqlApostrophe">
<xsl:param name="string" />
<xsl:variable name="apostrophe">'</xsl:variable>
<xsl:choose>
<xsl:when test="contains($string,$apostrophe)">
<xsl:value-of select="concat(substring-before($string,$apostrophe), $apostrophe,$apostrophe)"
disable-output-escaping="yes" />
<xsl:call-template name="sqlApostrophe">
<xsl:with-param name="string"
select="substring-after($string,$apostrophe)" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$string"
disable-output-escaping="yes" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="text()">
<xsl:call-template name="sqlApostrophe">
<xsl:with-param name="string" select="."/>
</xsl:call-template>
</xsl:template>
</xsl:stylesheet>
UPDATE: it works fine
Thanks for your help
The main problem is in your last template. As dacracot points out, xsl:apply-templates does not take a name attribute. To call a named template, you'd use xsl:call-template.
If you want to apply your SQL escaping to all text nodes, you could try replacing your last template with something like this:
<xsl:template match="text()">
<xsl:call-template name="sqlApostrophe">
<xsl:with-param name="string" select="."/>
</xsl:call-template>
</xsl:template>
Also, why disable-output-escaping? If the text contains special characters (<, >, &), you'll get malformed XML as the output.
You have a couple of issues syntactically...
You can't have a name attribute on an apply-templates tag.
Your xpath, "node()|#*", is ambiguous.
Have you run this through a debugger? I would suggest Oxygen.
I want to use the Wikipedia API to find the French pages including the ''SQLTemplate:Infobox Scientifique'' missing in the English version. So, my idea was to process the following document with xproc:
http://fr.wikipedia.org/w/api.php?action=query&format=xml&list=embeddedin&eititle=Template:Infobox%20Scientifique&eilimit=400
and the following xslt stylesheet:
<?xml version='1.0' ?>
<xsl:stylesheet
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
version='1.0'
>
<xsl:output method='text' indent="yes"/>
<xsl:template match="/">
<xsl:apply-templates select="api"/>
</xsl:template>
<xsl:template match="api">
<xsl:for-each select="query/embeddedin/ei">
<xsl:variable name="title" select="translate(#title,' ','_')"/>
<xsl:variable name="english-title">
<xsl:call-template name="englishTitle"><xsl:with-param name="title" select="#title"/></xsl:call-template>
</xsl:variable>
<xsl:value-of select="$english-title"/><xsl:text>
</xsl:text>
</xsl:for-each>
</xsl:template>
<xsl:template name="englishTitle">
<xsl:param name="title"/>
<xsl:variable name="uri1" select="concat('http://fr.wikipedia.org/w/api.php?action=query&format=xml&prop=langlinks&lllimit=500&titles=',translate($title,' ','_'))"/>
<xsl:message><xsl:value-of select="$uri1"/></xsl:message>
<xsl:message>count=<xsl:value-of select="count(document($uri1,/api/query/pages/page/langlinks/ll))"/></xsl:message>
</xsl:template>
</xsl:stylesheet>
The XSLT extract all the articles containing the Template and for each article I wanted to call Wikipedia to get the links between the wikis. Here the template englishTitle calls the xpath function document().
But it always says that count(ll)=1 whereas there are plenty nodes. (e.g. http://fr.wikipedia.org/w/api.php?action=query&format=xml&prop=langlinks&lllimit=500&titles=Carl_Sagan ).
Can't I process the nodes returned by the document() function?
You should try:
<xsl:value-of select="count(document($uri1)/api/query/pages/page/langlinks/ll)"/>
On a different note - what is
translate(#title,' ','_')
supposed to mean? What's wrong with:
translate(#title, ' ', '_')
There is no need to encode single quotes in XML attributes unless you want to use a type of quote that delimits the attribute value. All of these are valid:
name="foo"'foo"
name='foo'"foo'
Your entire transformation can be reduced to something like this:
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
<xsl:output method="text" />
<xsl:param name="baseUrl" select="'http://fr.wikipedia.org/w/api.php?action=query&format=xml&prop=langlinks&lllimit=500&titles='" />
<xsl:template match="ei">
<xsl:variable name="uri" select="concat($baseUrl ,translate(#title,' ','_'))"/>
<xsl:variable name="doc" select="document($uri)"/>
<xsl:value-of select="$uri"/>
<xsl:text>
</xsl:text>
<xsl:text>count=</xsl:text>
<xsl:value-of select="count($doc/api/query/pages/page/langlinks/ll)"/>
<xsl:text>
</xsl:text>
</xsl:template>
<xsl:template match="text()" />
</xsl:stylesheet>
Let the XSLT default templates work for you - they do all of the recursion in the background, all you have to do is catch the nodes you want to process (and prevent output of unnecessary text by overriding the default text() template with an empty one).
