Extra xmlns attributes being added to children elements - Java Saxon-EE 11.3
Added by Cory Madden about 2 years ago
Hi There,
I have noticed that with Saxon 11.3 adds extra namespace attributes to the children elements when using xsl:mode. XSL
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="3.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:mode on-no-match="shallow-copy" />

xsl:mode on-no-match="shallow-copy"
does an identity transformation where in scope namespace nodes are copied too, so the xmlns:ouc="..."
which is in scope from the ancestor declaration is output on the div
child correctly, by the serializer, in my view, as no ancestor was copied.

Saxon's output here is definitely correct: shallow copy of an element, whether done explicitly using xsl:copy or implicitly using the built-in template rule, is required to copy all the in-scope namespaces of the element being copied.
I've run it under 9.7 and that appears to deliver the same (correct) result.
If you want to drop unused namespaces, try adding a fallback template rule
<xsl:template match="*">
<xsl:copy copy-namespaces="no">
<xsl:apply-templates select="@*, node()"/>
</xsl:copy>
</xsl:template>

Thank you for the comments. I took my example code and processed it through Saxon 9.7.0.2 and Saxon 11.3. The xsl:mode on-no-match="shallow-copy" works differently in the two versions.
In Saxon 9.7.0.2: (example page https://cory-gallena.oudemo.com/testing.html does contain some of our system code at the bottom of the HTML)
<!DOCTYPE HTML>
<html>
<body>
<div class="item-9">
<h1>This is output with Saxon 9.7.0.2</h1>
</div>
</body>
</html>
In Saxon 11.3: (example https://program-examples.oudemo.com/xsl-question/test.html does contain some of our system code)
<!DOCTYPE HTML>
<html>
<body>
<div xmlns:ouc="http://omniupdate.com/XSL/Variables" class="item-9">
<h1>This should output</h1>
</div>
</body>
</html>
Full code example (with our system code) XSL:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="3.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:ou="http://omniupdate.com/XSL/Variables"
xmlns:fn="http://omniupdate.com/XSL/Functions"
xmlns:ouc="http://omniupdate.com/XSL/Variables"
exclude-result-prefixes="xsl xs ou fn ouc">
<xsl:output method="html" version="5.0" indent="yes" encoding="UTF-8" />
<xsl:mode on-no-match="shallow-copy" />
<xsl:template match="processing-instruction('pcf-stylesheet')" mode="#all" />
<xsl:template match="ouc:*">
<xsl:apply-templates mode="#current" />
</xsl:template>
<xsl:template match="/document">
<html>
<body>
<xsl:apply-templates select="ouc:div[@label='mylabel']" />
</body>
</html>
</xsl:template>
</xsl:stylesheet>
XML:
<?xml version="1.0" encoding="UTF-8"?>
<?pcf-stylesheet path="/common.xsl" extension="html" ?>
<document xmlns:ouc="http://omniupdate.com/XSL/Variables">
<ouc:div label="mylabel" group="Everyone">
<div class="item-9">
<h1>This is output with Saxon 11.3</h1>
</div>
</ouc:div>
</document>
Can you confirm this the new desired behavior?

The behaviour changed in Saxon 9.7.0.6 as a result of fixing bug #2767 - see https://saxonica.plan.io/issues/2767

Thank you for the clarification! I will inform our team of this change, I will repost if they have any additional questions.
