xalan:evaluate()
Hi fop-users,
In former messages I red an example with xalan:evaluate() and that's exactly
what I need at the moment. But unfortunately it doesn't work.
At first my old (working) xsl-stylesheet:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:fox="http://xml.apache.org/fop/extensions"
version="1.0">
...
<xsl:template name="list">
<xsl:for-each
test="//FORMULA/FORMULA-CAPTION[not(ancestor::APPENDIX)]">
<!-- put in a list -->
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
The expression "not(ancestor::APPENDIX)" is much more longer,I need it more
than 25 times and so I want to use a variable. Here's my new (_not_ working)
stylesheet:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:fox="http://xml.apache.org/fop/extensions"
xmlns:xalan="http://xml.apache.org/xslt"
version="1.0">
<xsl:variable name="not-in-appendix">not(ancestor::APPENDIX)</xsl:variable>
...
<xsl:template name="list">
<xsl:for-each
select="//FORMULA/FORMULA-CAPTION[xalan:evaluate($not-in-appendix)]">
<!-- put in a list -->
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
I get the following error-message:

This has nothing to do with FOP. Get Xalan, run you XSLT
standalone, and if it persists, read the Xalan docs and
finally ask on the Xalan list.
