> following:
> <xsl:variable name="var1>
> <info1 value="test" />
> <info2 value="test" />
> </xsl:variable>
> and I pass thi vaiable to an extension function :
> <xsl:copy-of select="myext:getdata2($var1)" />
> I defined my function as follows:
> public Document getdata2(Object input){
> DTMNodeIterator it = (DTMNodeIterator) input;
> Document inputDoc = (Document) it.getRoot();
> ....
> }
> When I dump the inputdoc to file, it contains the data from var1 as I expect.
> Now I try to get specific data from the input doc with the XPathAPI object,
> e..g.
> XPathAPI.selectNodeList(inputDoc,"/")
> but this gives met the following error
> java.lang.ArrayIndexOutOfBoundsException: -1
