Hello,
I am trying to create a online questionnaire using xsp, xml data and a
xsl transform but I get the following error when using
TransformArgumentList:
System.Xml.XPath.XPathException: expected nodeset: $qload
in <0x0012d> System.Xml.XPath.Expression:EvaluateNodeSet (System.Xml.XPath.BaseIterator iter)
in <0x0001a> System.Xml.XPath.ExprSLASH:Evaluate (System.Xml.XPath.BaseIterator iter)
in <0x00060> System.Xml.XPath.Expression:EvaluateNodeSet (System.Xml.XPath.BaseIterator iter)
in <0x0016a> System.Xml.XPath.EqualityExpr:EvaluateBoolean (System.Xml.XPath.BaseIterator iter)
in <0x00011> System.Xml.XPath.CompiledExpression:EvaluateBoolean (System.Xml.XPath.BaseIterator iter)
....... (many more lines)
Could someone please have a look at the test below and tell me what/if I
am doing wrong? I was able to create a gtk#/gecko# app using the same
data so I think it is a problem with asp:xml.
I have tried with Mono 1.1.8.3 and gentoo on x86 and ppc.
Cheers,
Mark
