XSL Transform Prevented by a Declaration

[Al Hatch]

XSLT fails when the XML file contains this top-level declaration:

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<P2Main xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="urn:schemas-Professional-Plug-in2:ClipMetadata:v3.0">
<ClipName>0001FM</ClipName>
</P2Main>

However, XSLT succeeds when I modify the XML declaration to this:

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<P2Main>
<ClipName>0001FM</ClipName>
</P2Main>

What is the declaration conflict here, and why would that simple deletion
make it work?


By the way, the XSL is

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:value-of select="P2Main/ClipName"/>
</xsl:template>
</xsl:stylesheet>

</P2Main>

<xsl:stylesheet version="1.0"
Add
xmlns:cm="urn:schemas-Professional-Plug-in2:ClipMetadata:v3.0"

xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

and then use e.g.

<xsl:template match="/">
<xsl:value-of select="P2Main/ClipName"/>

<xsl:value-of select="cm2Main/pm:ClipName" />

 

[Al Hatch]

<xsl:value-of select="cm2Main/pm:ClipName" />

There was a typo in your repsonse (/pm should be /cm), but once I changed
that, it worked.

Apparently, namespace declarations in the XSL document must match the
namespace declarations in its source XML document, but I'm not clear on what
the cm namespace is. I guess I have to go back to the manual to find out
what's going on here.

Thanks.

The major problem is that while the XML document contains elements in a
default namespace (declared with xmlns="someURI") XPath needs a prefix
bound to the URL to match elements in the namespace.
