Goog Morning, Im using a simple xsl to tranform an imput xml that sometimes has the empty element “ContentVersion”, the xsl adds a “dummy” element when it’s empty, it works fine but in a specific server (windows Server 2019) the output is different, this is the input sample xml:

<?xml version="1.0" encoding="UTF-8"?>
<CompositionPlaylist xmlns="http://www.sample.com/SAMPLE-20040511#">
    <Id>urn:uuid:129de837-6eed-40d4-a635-db58380dfd9e</Id>
    <AnnotationText>Title</AnnotationText>
    <IssueDate>2014-09-22T19:18:56.001+01:00</IssueDate>
    <Issuer>issuer</Issuer>
    <Creator>Creator Name</Creator>
    <ContentTitleText>Content Title</ContentTitleText>
    <ContentKind>feature</ContentKind>
    <ContentVersion>
        <ContentVersion>
            <LabelText/>
        </ContentVersion</ContentVersion>
        <RatingList/>

the xsl is this:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="2.0" xmlns:ns1="http://www.sample.com/SAMPLE-20040511#" exclude-result-prefixes="ns1" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
    <!-- identity transform -->
    <xsl:template match="@* | node()">
        <xsl:copy>
            <xsl:apply-templates select="@* | node()"/>
        </xsl:copy>
    </xsl:template>
    <!--Add dummy "id" and "LabelText"  if "LabelText" is empty-->
    <xsl:template match="ns1:ContentVersion[not(ns1:LabelText) or ns1:LabelText = '']">
        <ContentVersion xmlns="http://www.sample.com/SAMPLE-20040511#">
            <Id>urn:uuid:11111111-1111-1111-1111-111111111111</Id>
            <LabelText>DUMMY</LabelText>
        </ContentVersion>
    </xsl:template>
</xsl:stylesheet>

from most of PC I have used the output (just the modified element) is:

<ContentVersion>
    <Id>urn:uuid:11111111-1111-1111-1111-111111111111</Id>
    <LabelText>DUMMY</LabelText>
</ContentVersion>

the output from another server is:

<ContentVersion>
    <LabelText>1.0</LabelText>
</ContentVersion>

so different, I used some different XML tools to parse the xml file but, in this machine, the result is always different, I didn’t find a solution yet, can somebody help me to understand the different behavior?
