Xalan Developers: I found the following bug in xalan 2.4.1D
The key() function throws an exception when called in the context of a local variable. Here is an extremely small transform that can be used to reproduce the problem. I have verified that this transform works fine in 2.3.1 but does not work in 2.4.1D. I use the key() function in this manner often in my current application. <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:xalan="http://xml.apache.org/xalan"; extension-element-prefixes="xalan"> <!-- This style sheet illustrates a bug in xalan 2.4D1 when using the key function against a computed node set. This example works in 2.3.1 August 11, 2002 Nancy Lehrer, Sr. Architect JumpStart Wireless Corporation [EMAIL PROTECTED] Test this style sheet with an input XML doc that looks something like this: <lookups> <item name="a">This is A</item> <item name="b">This is B</item> <item name="c">This is C</item> </lookups> --> <xsl:key name="item-lookup" match="item" use="@name" /> <xsl:template match="/lookups" > <xsl:variable name="more" > <more-items> <item name="c">This is more C</item> <item name="z">This is more Z</item> </more-items> </xsl:variable> Lookup C: <xsl:copy-of select="key('item-lookup', 'c')"/> <!-- This section does not work in xalan 2.4D1, but does work in xalan 2_3_1 --> <!-- In 2.4D1 it is not just that they product no results, but an exception is thrown --> <xsl:for-each select="xalan:nodeset($more)"> Lookup Z: <xsl:copy-of select="key('item-lookup', 'z')" /> Lookup C again: <xsl:copy-of select="key('item-lookup', 'c')" /> </xsl:for-each> </xsl:template> </xsl:stylesheet> I hope this helps you continue to make Xalan and premier product!

I am however slightly annoyed at how difficult it is to find the 2.3.1 release on the website. From my perspective it should be extremely obvious how to download the last non-developer release from http://xml.apache.org/xalan-j/index.html page. There is no reference to it there. I found it from the home apache.org page.
