I have XML form data coming in from a vendor app that allows me to select values for fields on the form by using this format.
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xsl:stylesheet version="1.0" xmlns="http://www.w3.org/1999/XSL/Transform" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<xsl:output method="text" /><xsl:template match="/"><xsl:apply-templates/></xsl:template>
<xsl:template match="DataSet/diffgr:diffgram/Forms">
<xsl:for-each select="Form">
<xsl:value-of select="FieldName1"/>
<xsl:value-of select="FieldName2"/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
I can't see the XML, but I can surmise from this that all of the fields are siblings within the <form> and looks something like this:
<form>
<CosignerName1 value="John Doe"/>
<CosignerDate1 value="1/1/1970"/>
<CosignerTime1 value="8:46 PM"/>
<CosignerName2 value="Jane Smith"/>
<CosignerDate2 value="2/2/1972"/>
<CosignerTime2 value="11:46 AM"/>
...
<CosignerName12 value="Will Hunting"/>
<CosignerDate12 value="12/12/1982"/>
<CosignerTime12 value="1:00 AM"/>
</form>
<form>
<CosignerName1 value="Bill Thomas"/>
<CosignerDate1 value="5/5/2020"/>
<CosignerTime1 value="8:46 PM"/>
<CosignerName2 value="Bev Poole"/>
<CosignerDate2 value="6/6/2022"/>
<CosignerTime2 value="11:46 AM"/>
...
<CosignerName12 value="Bob Ross"/>
<CosignerDate12 value="12/12/1982"/>
<CosignerTime12 value="1:00 AM"/>
</form>
Known factors:
Each form has 12 cosigners, each with numbered field names i.e. CosignerName1, CosignerName2, etc.
Each named cosigner also has a CosignerDate and a CosignerTime field associated by number. i.e. CosignerName1 has CosignerDate1 and CosignerTime1 fields that, when combined, show when that user signed the form.
I am using the word 'idnum' in my code and in this question to refer to the number at the end of each label that shows they are part of a set i.e CosignerName1, CosignerDate1, and CosignerTime1 all share idnum=1
Goal: Identify and select only the most recent CosignerName, based on CosignerDate and CosignerTime.
To do this, I figure I need to:
Find the most recent CosignerDate/CosignerTime combination
Read the label of either of the identified fields to extract the idnum from the end
Use the idnum to to identify the correct CosignerName and output it
I have some pieces of the solution, but no way to bring them together:
Create a Timestamp
I can combine a set of CosignerDate[idnum] and CosignerTime[idnum] fields, then translate them into a timestamp. If I could create an array of these timestamps, then I could sort and find the most recent one, but as I understand it XSLT 1.0 doesn't have arrays. So I am not sure what to do with this.
<xsl:variable name="mm" select="substring-before(CosignerDate1,'/')" />
<xsl:variable name="mmyyyy" select="substring-after(CosignerDate1,'/')"/>
<xsl:variable name="dd" select="substring-before($mmyyyy,'/')" />
<xsl:variable name="yyyy" select="substring-after($mmyyyy,'/')" />
<xsl:variable name="ampm" select="substring-after(CosignerTime1,' ')" />
<xsl:variable name="time">
<xsl:choose>
<xsl:when test="$ampm = 'AM'">
<xsl:value-of select="number(translate(substring-before(CosignerTime1,' '),':',''))" />
</xsl:when>
<xsl:when test="$ampm = 'PM'">
<xsl:value-of select="number(translate(substring-before(CosignerTime1,' '),':',''))+number('1200')" />
</xsl:when>
</xsl:choose>
</xsl:variable>
<xsl:value-of select="concat('Timestamp:',$yyyy,$mm,$dd,$time)"/>
The code above outputs something like: Timestamp:202209191128
Get idnums
I can loop through all of the Cosigners and extract the identifying number shared by their labels.
<xsl:for-each select="*[starts-with(local-name(), 'CosignerName')]">
<xsl:variable name="idnum">
<xsl:value-of select="translate(local-name(),'CosignerName','')" />
</xsl:variable>
<xsl:value-of select="$idnum"/>
<xsl:value-of select="','"/>
</xsl:for-each>
This code above outputs something like: 1,4,7,12
But, this is where I get lost.
Failed Attempt
I tried something like the code below. The logic was to loop through each Cosigner name (12 iterations), get the idnum from the label, use that to get the CosignerDate and CosignerTime, create a timestamp, then sort the timestamps, if the timestamp we are looking at is the top one (most recent) then use the idnum to select the correct CosignerName and output it.

</xsl:for-each>

</xsl:for-each>

</xsl:stylesheet>
This of course fails for several reasons:
the concat with the $idnum doesn't actually pull values from fields
the sort has to be the first thing in the for-each
the sort has to happen after all of the timestamps are created
the sorted list of timestamps still needs to reference which idnum they were generated from
Without being able to create an array of timestamps and idnums, I don't know how you can accomplish this.
Does anyone know how can I get at the CosignerName[idnum] that is correlated with the most recent CosignerDate[idnum]/CosignerTime[idnum]?
I believe you could just sort the CosignerNameX nodes by the individual components of their associated dates and times, as shown in the two other answers I linked to:
https://stackoverflow.com/a/59288030/3016153
https://stackoverflow.com/a/30631073/3016153
However, it might be more efficient - and certainly more readable - to do this in two steps:
Construct a dateTime value for each cosigner;
Find the cosigner with the most recent value.
Consider the following example:
XML
<DataSet xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1">
<diffgr:diffgram>

P.S. With a Microsoft processor you may need to change the namespace declaration:
xmlns:exsl="http://exslt.org/common"
to:
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
and then change the exsl prefix in lines #5 and #39 to msxsl.
In a BizTalk mapper, I had to set a default e-mail in output field when a specific input field is null or empty.
So I set an XSLT variable with the email but when the condition is good no node is created in the output.
Here is my code:
<xsl:template name="GetEmail">
<xsl:param name="number" />
<xsl:param name="Email" />
<xsl:variable name="defaultmail">noreply#domain.fr</xsl:variable>
<xsl:for-each select="//*[local-name()='Employee']">
<xsl:choose>
<xsl:when test="*[local-name()='Username' and text() = $number] and $Email != ''">
<xsl:element name="email">
<xsl:value-of select="string(*[local-name()='Email'])" />
</xsl:element>
</xsl:when>
<xsl:when test="*[local-name()='Username' and text() = $number] and $Email = ''">
<xsl:element name="email">
<xsl:value-of select="$defaultmail" />
</xsl:element>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</xsl:template>
Here is my Input file:
<ns0:Root xmlns:ns0="http://schemas.microsoft.com/BizTalk/2003/aggschema">
<InputMessagePart_0>
<Get>
<Employee>
<Username>008441</Username>
<Email />
</Employee>
<Employee>
<Username>014095</Username>
<Email>email2#domain.fr</Email>
</Employee>
<Employee>
<Username>011812</Username>
<Email>email3#domain.fr</Email>
</Employee>
</Get>
</InputMessagePart_0>
<InputMessagePart_1>
<ns1:EmployeeResponse xmlns:ns1="http://Employee">
<ns1:Header />
<ns1:Return>
<ns1:Employee>
<ns1:Number>008441</ns1:Number>
</ns1:Employee>
</ns1:Return>
</ns1:EmployeeResponse>
</InputMessagePart_1>
</ns0:Root>
And here is the output:
<Employee>
<username>123456789</username>
<firstname>Firstname</firstname>
<lastname>Lastname</lastname>
<birthdate>dd/MM/yyyy</birthdate>
<email />
</Employee>
And what it should be:
<Employee>
<username>123456789</username>
<firstname>Firstname</firstname>
<lastname>Lastname</lastname>
<email>noreply#domain.fr</email>
<birthdate>dd/MM/yyyy</birthdate>
</Employee>
I have 2 input files, one is provided by my customer and the other is provided by our DB.
The first file from customer contains a list of employees.
The second file from our DB contains only one employee identified with the Username in the first file. There is a loop so for each employee in the first file we get the employee datas related to Username. We need two datas in our DB related to each employee to calculate 2 fields in output file.
The output must contains all datas from the first one and the 2 calculated fields.
If the email field is not provided (empty or null) in the first file (from my customer), BizTalk mapper take the email of the next employee with an non empty email field.
So in my example, the output will be:
<Employee>
<username>008441</username>
<firstname>Firstname</firstname>
<lastname>Lastname</lastname>
<email>email2#domain.fr</email>
<birthdate>dd/MM/yyyy</birthdate>
</Employee>
instead of :
<Employee>
<username>008441</username>
<firstname>Firstname</firstname>
<lastname>Lastname</lastname>
<email>noreply#domain.fr</email>
<birthdate>dd/MM/yyyy</birthdate>
</Employee>
You should NOT try to link from both InputMessagePart_0 and InputMessagePart_1, that just confuses the looping, and you are already creating the loop inside the XSLT for InputMessagePart_0 with your for-each-select. Just link the Number from InputMessagePart_1 and use the following XSLT. Also select the Email from the node, and not pass it in as a variable.
<xsl:template name="GetEmail">
<xsl:param name="number" />
<xsl:variable name="defaultmail">noreply#domain.fr</xsl:variable>
<xsl:for-each select="//*[local-name()='Employee']">
<xsl:choose>
<xsl:when test="*[local-name()='Username' and text() = $number]">
<xsl:choose>
<xsl:when test="*[local-name()='Email' and text() != '']">
<xsl:element name="email">
<xsl:value-of select="string(*[local-name()='Email'])" />
</xsl:element>
</xsl:when>
<xsl:otherwise>
<xsl:element name="email">
<xsl:value-of select="$defaultmail" />
</xsl:element>
</xsl:otherwise>
</xsl:choose>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</xsl:template>
change your code to:
<xsl:template name="GetEmail">
<xsl:param name="number" />
<xsl:param name="Email" />
<xsl:variable name="defaultmail">
<xsl:value-of select='noreply#domain.fr'/>
</xsl:variable>
<xsl:for-each select="//*[local-name()='Employee']">
<xsl:choose>
<xsl:when test="[local-name()='Username' and text() = $number] and string-length($Email) >0">
<xsl:element name="email">
<xsl:value-of select="string(*[local-name()='Email'])" />
</xsl:element>
</xsl:when>
<xsl:when test="*[local-name()='Username' and text() = $number] and string-length($Email) &eq;0">
<xsl:element name="email">
<xsl:value-of select="$defaultmail" />
</xsl:element>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</xsl:template>
I have an XML file for which I have to frame XSL so that my ETL job can process it. Here is what i need.
Input XML
<FS_Sub_Investment_Team>
<Report Name="REPORT">
<MeetTheTeamTableHeading Label="TEAM" />
<MeetTheTeamTable>
<Rows>
<Row ManagerData="ABC EFGHI XYZ" />
<Row ManagerData="ABC PQRST XYZ" />
</Rows>
</MeetTheTeamTable>
<MeetTheTeamNote></MeetTheTeamNote>
</Report>
</FS_Sub_Investment_Team>
Current XSL:
<xsl:template match="/">
<Bio>
<BioText>
<xsl:apply-templates select="//Row/#ManagerData" mode="concat"/>
</BioText>
</Bio>
</xsl:template>
Current Output :
<Bio><BioText>ABC EFGHI XYZABC PQRST XYZ</Bio></BioText>
My expected output is: With line break (or) with space between the two element values, please give me both solutions.
<Bio><BioText>ABC EFGHI XYZ
ABC PQRST XYZ</Bio></BioText>
Try:
<xsl:template match="/">
<Bio>
<BioText>
<xsl:for-each select="//Row">
<xsl:value-of select="#ManagerData" />
<xsl:if test="position()!=last()">
<xsl:text>
</xsl:text>
</xsl:if>
</xsl:for-each>
</BioText>
</Bio>
</xsl:template>
To insert a space instead of a new line, use:
<xsl:text> </xsl:text>
instead of:
<xsl:text>
</xsl:text>
I have a value in an element as 433554567643.
I would like to change it to 43 35545 67643. The grouping should start from right side of the value.
Is it possible to use subtring from end to start of the value?
Thanks.
You could do this with a recursive template.
<xsl:template name="add-spaces">
<xsl:param name="group" select="5" />
<xsl:param name="text" />
<xsl:if test="string-length($text) > $group">
<xsl:call-template name="add-spaces">
<xsl:with-param name="group" select="$group" />
<xsl:with-param name="text"
select="substring($text, 1, string-length($text) - $group)" />
</xsl:call-template>
<xsl:text> </xsl:text>
</xsl:if>
<xsl:value-of select="substring($text, string-length($text) - $group + 1)" />
</xsl:template>
You would call this when required using
<xsl:call-template name="add-spaces">
<xsl:with-param name="text" select="'433554567643'" />
<!-- or select="path/to/element" as appropriate -->
</xsl:call-template>
If your value is always a number, you could use format-number() with a pattern that groups the numbers by 5 digits and then translate() the "," into " ":
<xsl:value-of select="translate(format-number('433554567643', '#,#####'),
',', ' ')" />
Is it possible to have a better solution for the following:
Input xml
<product>
<text>
<languageId>en-us</languageId>
<description>some text en us</description>
</text>
<text>
<languageId>en-gb</languageId>
<description>some text en gb</description>
</text>
<text>
<languageId>en-us</languageId>
</text>
<product>
Output xml
<specifications>some text en us</specifications>
So, if there is a description with languageId = en-us and there is text present, then this text will be placed in the output xml, otherwise the element receives the attribute value xsi:nil=true
xslt version must be 1.0
XSLT
<ns0:specifications>
<!-- First loop, check if en-us is present, if so, check if there is a text! -->
<!-- If the 2 requirements are met, then this Txt element is used -->
<xsl:for-each select="s0:text">
<xsl:if test="translate(s0:LanguageId/text(),$smallcase,$uppercase)=translate('en-us',$smallcase,$uppercase)">
<xsl:if test="s0:Txt!=''">
<xsl:value-of select="s0:Txt/text()" />
</xsl:if>
</xsl:if>
</xsl:for-each>
<!-- Second loop, checks are the same. This loop is needed because xsl variables are immutable. If there is a better solution, just change the code!! -->
<!-- If the 2 requirements are met, then the variable is marked as true, else it's empty -->
<xsl:variable name="isEnUsPresent">
<xsl:for-each select="s0:text">
<xsl:if test="translate(s0:LanguageId/text(),$smallcase,$uppercase)=translate('en-us',$smallcase,$uppercase)">
<xsl:if test="s0:Txt!=''">
<xsl:value-of select="1" />
</xsl:if>
</xsl:if>
</xsl:for-each>
</xsl:variable>
<!-- if the variable is empty, set the attribute value xsi:nil=true like below -->
<xsl:choose>
<xsl:when test="$isEnUsPresent=''">
<xsl:attribute name="xsi:nil">
<xsl:value-of select="'true'" />
</xsl:attribute>
</xsl:when>
</xsl:choose>
</ns0:specifications>
