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.

How do you replace an xml value, for example:
<name>Linda O'Connel</name>
to:
<name>Linda O''Connel</name>
via XSLT?
I need this because I have to pass this value in a powershell command line and to other platforms since the "double single quote" is needed to escape the apostrophe/single quotes.
Assuming an XSLT 1.0 processor, you will need to use a recursive named template for this, e.g:
<xsl:template name="replace">
<xsl:param name="text"/>
<xsl:param name="searchString">'</xsl:param>
<xsl:param name="replaceString">''</xsl:param>
<xsl:choose>
<xsl:when test="contains($text,$searchString)">
<xsl:value-of select="substring-before($text,$searchString)"/>
<xsl:value-of select="$replaceString"/>
<!-- recursive call -->
<xsl:call-template name="replace">
<xsl:with-param name="text" select="substring-after($text,$searchString)"/>
<xsl:with-param name="searchString" select="$searchString"/>
<xsl:with-param name="replaceString" select="$replaceString"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
Example of call:
<xsl:template match="name">
<xsl:copy>
<xsl:call-template name="replace">
<xsl:with-param name="text" select="."/>
</xsl:call-template>
</xsl:copy>
</xsl:template>
You can also try out the following.
<xsl:variable name="temp">'</xsl:variable>
<name>
<xsl:value-of select="concat(substring-before(name,$temp),$temp,$temp,substring-after(name,$temp))"/>
</name>
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 have to sum the values from xml and remove the Trailing zeros from xml.
can you help me to remove this using xsl1.0 or xslt2.0
I have tried with number(.) but its not removing the trailing zeros.
My input is below
<test>
<loop>
<lines>
<linesTotal>2010</linesTotal>
</lines>
<lines>
<linesTotal>20</linesTotal>
</lines>
</loop>
</test>
Expected output is
203
but it results 2030
Please help me!
I can't see why this would be useful (at least not in the given example), and I strongly suspect you don't really want to do this.
But - mainly for fun - here's a method to remove any trailing zeros from the result:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/test">
<output>
<xsl:call-template name="remove-trailing-zeros">
<xsl:with-param name="number" select="sum(loop/lines/linesTotal)"/>
</xsl:call-template>
</output>
</xsl:template>
<xsl:template name="remove-trailing-zeros">
<xsl:param name="number"/>
<xsl:choose>
<xsl:when test="$number and not($number mod 10)">
<xsl:call-template name="remove-trailing-zeros">
<xsl:with-param name="number" select="$number div 10"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$number"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
In XSLT 2.0, you could make this a function instead of a template. Or move the problem to the string domain (as suggested in another answer):
<xsl:template match="/test">
<xsl:param name="sum" select="sum(loop/lines/linesTotal)"/>
<output>
<xsl:value-of select="replace(string($sum), '0+$', '')"/>
</output>
</xsl:template>
You can use replace function using 2.0:
replace(string(2010+30), '0$', '')
I need to replace values of multiple elements of an input xml. The input file has around 300 elements of which I need to replace around 100 elements. I have used identity template before, but I think it would require me to write 100 different templates each for replacing a single element value. I am not very good at xslts, so, am I thinking it right, or is there a better an elegant approach? Please advice.
Edit
Here is the Link of sample input xml.
The output will have almost the same structure, but different values for some of the elements.
Well, something I did similar before before so I am happy to share ... modified to your example BUT does not do the value mapping, it does name mapping.
First create a simple mapping file like this (NOTE: you would need the namespaces to do this right
<env:map xmlns:env="http://www.w3.org/2003/05/soap-envelope">
<elem old="CardCode" new="CodeCardNEW"/>
<elem old="CardName" new="IAMNew"/>
</env:map>
Then one template will do you with a lookup. There are likely better ways to do the mapping, I am just for-each looping over them all ... a key would be better. But this gets you there.
Output from your file with above:
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
<env:Body>
<GetByKeyResponse>
<BOM>
<BO>
<AdmInfo>
<Object>oBusinessPartners</Object>
</AdmInfo>
<BusinessPartners>
<row>
<CodeCardNEW>CR43WEB</CodeCardNEW>
<IAMNew>Zack Burns</IAMNew>
<CardType>cCustomer</CardType>
...
And here's the XSL:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:env="http://www.w3.org/2003/05/soap-envelope"
version="1.0">
<xsl:param name="map" select="document('map.xml')/env:map"></xsl:param>
<xsl:template match="text()" priority="1">
<xsl:value-of select="."/>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:variable name="newname">
<xsl:call-template name="namesub">
<xsl:with-param name="name" select="name()"/>
</xsl:call-template>
</xsl:variable>
<xsl:element name="{$newname}">
<xsl:apply-templates select="#*|node()"/>
</xsl:element>
</xsl:template>
<xsl:template name="namesub">
<xsl:param name="name"/>
<xsl:variable name="newname">
<xsl:for-each select="$map/elem">
<xsl:choose>
<xsl:when test="#old = $name">
<xsl:value-of select="#new"/>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</xsl:variable>
<xsl:choose>
<xsl:when test="string-length($newname) > 0">
<xsl:value-of select="$newname"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$name"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
You should be able to adapt this as long as you have a match on name ... if the name is the same in different hierarchies of the XML, you would need more work.
This question (and my problem) is similar to XSLT1 Get the first occurence of a specific tag... But I have an "Undefined variable" error.
I have a XML with refpos attribute, that can be make by this first XSLT,
<xsl:template match="p[#class='ref']">
<xsl:copy>
<xsl:attribute name="refpos">
<xsl:value-of select="position()"/>
</xsl:attribute>
<xsl:apply-templates />
</xsl:copy>
</xsl:template>
<xsl:template match="#*|node()" name="idt">
<xsl:copy><xsl:apply-templates select="#*|node()"/></xsl:copy>
</xsl:template>
Then, I a main (second) XSLT I have,
<xsl:variable name="firstRef">
<xsl:value-of select="(//p[#class='ref'])[1]/#refpos"/>
</xsl:variable>
<xsl:template match="p[#refpos=$firstRef]">
<title><xsl:apply-templates /></title>
</xsl:template>
<xsl:template match="#*|node()" name="idt">
<xsl:copy><xsl:apply-templates select="#*|node()"/></xsl:copy>
</xsl:template>
But here this XSLT not works!!
PS: I also believe that XSLT1 allow us to do everything in one step.
XSLT 1.0 does not allow variable references in template match expressions (XSLT 2.0 does). You'll have to move the check from the predicate inside the template:
<xsl:template match="p">
<xsl:choose>
<xsl:when test="#refpos=$firstRef">
<title><xsl:apply-templates /></title>
</xsl:when>
<xsl:otherwise>
<xsl:call-template name="idt" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
