We have tested the evaluate function in saxon and it seems to run with
no detectable slow down.
We are having an issue using a global variable in the string. Here is the code: ------- <xsl:variable name="path" select="@path"/> <xsl:copy-of select="saxon:evaluate(concat('$contentDoc', $path))"/> --------- This is what saxon returns: --------- Warning: org.xml.sax.SAXParseException: Using original entity definition for """. Warning: org.xml.sax.SAXParseException: Using original entity definition for "&". Warning: org.xml.sax.SAXParseException: Using original entity definition for "<". Warning: org.xml.sax.SAXParseException: Using original entity definition for ">". Warning: org.xml.sax.SAXParseException: Using original entity definition for "'". Error at copy-of on line 107 of file:/var/www/localhost/site_system/master/data/cihost.com/transformation/layout.xsl: Variable $contentDoc has not been declared Transformation failed: Run-time errors were reported ------- It seems that the variable $contentDoc is not accessible from wherever it's being evaluated. Here is where we declare the variable: -------- <?xml version="1.0" ?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xhtml="http://www.w3.org/1999/xhtml" xmlns:pd="http://www.plauditdesign.com/pd" xmlns:saxon="http://saxon.sf.net/" xmlns="http://www.w3.org/1999/xhtml"> <xsl:output method="xml" version="1.0" encoding="iso-8859-1" indent="no" omit-xml-declaration="no"/> <!-- Incoming Content --> <xsl:param name="content"/> <xsl:variable name="contentDoc" select="document($content)"/> ------- Last thing I should probably note is that we are using Saxon 7.8 Thanks, Matt Michael Kay wrote: After some pretty exhaustive searching on the web, I have decided to join the list. I have noticed in the archives that more than one person has had the same issue as I have...how to create an XPath expression dynamically (from a variable, etc). The answer to these questions was to use any of the available *:evaluate functions. I would like to try to avoid that, since it increases the parse time so much....and that is not acceptable.
