I missed the fact that you're implementing the EXSLT regexp:match function
specifically. It's not clear to me why that function would need to have
access to the content of the xsl:for-each element. Isn't it purely a
function of its arguments?
I suggest you take a look at the ExsltStrings.tokenize method, which
implements the str:tokenize function, for ideas - though I know that
implementation has a memory leak. See [1] for details.
I hope that helps.
Thanks,
Henry
