how to reference data when a node has a XMLNS pointing to a DTD?

[Andy]

OK, I'm not sure what I'm missing here.

I'm working with this XML:

<?xml version="1.0" encoding="utf-8"?>
<GroupDataBlock xmlns="http://www.acme.com/data.dtd">
<GroupInfo>
<ProgramID>3002616</ProgramID>
</GroupInfo>
</GroupDataBlock>

and this XSL:

<?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="GroupDataBlock/GroupInfo/ProgramID" /><br />
</xsl:template>
</xsl:stylesheet>

Any idea why it won't show the ProgramID value?

Is there something in the DTD that I need to know to display this
correctly? Isn't the GroupInfo nested within the GroupDataBlock node?

Any help would be much appreciated.

Thanks,
Andy

Namespace declarations in xmlns don't really "point to" anything, the
URI is just a string identifying the namespace, it is never "looked up"

This is a FAQ. (see the faq for xsl-list for example)

<GroupDataBlock xmlns="http://www.acme.com/data.dtd">
so that is the element with name consisting of local name
GroupDataBlock
and namespace
http://www.acme.com/data.dtd
(it's unusual to use a dtd uri as a namespace, but anything would do,
xmlns="data:,hello"
for example.) The Processor will not look at the dtd file anyway.

<xsl:value-of select="GroupDataBlock/GroupInfo/ProgramID" />

that selects an element GroupDataBlock in no-namespace (and similarly
GroupInfo and ProgramID

add xmlns:x="http://www.acme.com/data.dtd" to your xsl:stylesheet
element so x: is in scope for the whole stylesheet then you can use

<xsl:value-of select="x:GroupDataBlock/x:GroupInfo/x:ProgramID" />

to select elements from this namespace.
