Parsing CDATA into a document
Is it possible in XSLT to parse a CDATA node into a document node (assuming
that there is a valid document in the CDATA node)?
For instance, in the following source document I would like to output the
CDATA content of INPUT as XML on the result document.
<INPUT name="PurchaseOrder" type="???">
<![CDATA[<?xml version="1.0" encoding="UTF-8"?>
<data>
<PurchaseOrder>
<contact type="string" />
<address type="string" />
<items>
<name type="string" />
<price type="double" />
<quantity type="int" />
</items>
<customer type="string" />
</PurchaseOrder>
</data>]]>
</INPUT>
The result should look like the following document:
<INPUT name="PurchaseOrder" type="???">
<data>
<PurchaseOrder>
<contact type="string" />
<address type="string" />
<items>
<name type="string" />
<price type="double" />
<quantity type="int" />
</items>
<customer type="string" />
</PurchaseOrder>
</data>
</INPUT>

No.
The best you can do is
<xsl:apply-templates select="INPUT">
<xsl:template match="INPUT">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:value-of select="." disable-output-escaping="yes"/>
</xsl:copy>
</xsl:template>
But this doesn't do validation of the output, and you will end up with an
illegal '<?xml version="1.0" encoding="UTF-8"?>' at the top of the <INPUT>.
You really really need to reconsider how and why it is necessary to include
the other XML as CDATA. You should really try to find another way to do it;
there are so many issues that will come up down the road. But if you can't
change it, then good luck!

No, most importantly because XSLT has no clue what's CDATA and what
isn't (and secondly because it can't parse strings). Don't use CDATA
sections as structure. They're syntax sugar, nothing more.
Exercise: go through your documents and replace all CDATA sections
with escaped text that uses < and &. If anything breaks,
you're doing something wrong.
