Re: [xslt] Problems using functions with xsl

["Pedro Rocha" <pedro_jrocha hotmail com>]

Hi,

Sorry... you're right - the error message was not exactly related with the 
xsl file I sent. The error message was reporting an error in line 14.

I'm doing the following program in C++:

	xsltStylesheetPtr XMLStyleSheetPtr = NULL;
	XMLStyleSheetPtr = xsltParseStylesheetFile((const xmlChar *)xsltFileName);
	exsltRegisterAll();
	xmlDocPtr XMLDocumentPtr = xsltApplyStylesheet (XMLStyleSheetPtr, 
XMLDocumentPtr, NULL);

This will apply the given stylesheet to a simple xml doc. I get the referred 
error message:

   xmlXPathCompOpEval: function testparam not found
   XPath error : Unregistered function
   xmlXPathCompiledEval: evaluation failed
   runtime error: file file:///c%3A/temp/xml/prueba.xsl line 14 element 
value-of
   xsltValueOf: text copy failed

Kind regards,

Pedro
