Hi, The following stylesheet gives error "XPDY0002: Cannot select a node here: the context item is undefined" in Saxon 9.1.0.5J. I understand that a function does not have a context node. But as the path is absolute, the loop range should be clear here. <?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:t="http://www.blahblah.org/demo"> <xsl:function name="t:show-bug"> <xsl:sequence select="for $i in /a/b/c return $i" /> </xsl:function> </xsl:stylesheet> Frank

The term "absolute" is misleading (and is no longer used in the XPath specification). A path starting with "/" selects relative to the root of the document that contains the context node. So if we don't know the context node, we don't know which document to search. You need to pass the relevant document node as a parameter; or if the stylesheet is only handling one document, you can bind it to a global variable: <xsl:variable name="root" select="/"> <xsl:function... <xsl:sequence select="$root/a/b/c" Michael Kay http://www.saxonica.com/
