[going back on list] > As I said, I am unable to use
as posted I get:
$ saxon filter.xml filter.xsl
Error at xsl:for-each on line 17 of file:/c:/tmp/filter.xsl: Key 'by-info' has not been defined Transformation failed: Run-time errors were reported
taking
<xsl:key name="by-info" match="Article" use="@info"/>
from an earlier post and adding it after xsl:stylesheet, I get:
$ saxon filter.xml filter.xsl <?xml version="1.0" encoding="utf-8"?>
<Documents> <Document name="sub"> <Article title="1.1" info="sub" filter="food"/> </Document> <Document name="main"> <Article title="2.2" info="main" filter="food"/> </Document> </Documents>
That is, apart from droping your key definintion, the code you posted works as expected. So if you really get
"Exception Details: System.NullReferenceException: Object reference not set to an instance of an object." in myXslTrans.Transform(myXPathDoc, null, writer, null);
looks like a bug in your processor (Microsoft .net implementation?)
