Wendell, Thank you for your answer. The problem is that I can't get expected result "1" "2". I don';t know how to get it. I have to use the key() in the project I am working on. Thanks again!

Any body can tell me what is wrong with ><xsl:key> Nothing's wrong with it, it's working fine. xsl:key indexes nodes across the entire document. When you write > <xsl:variable name="child" select="key('key-name', 'a1')" /> You are setting the variable $child to be *all* the nodes that match the key with key value 'a1'. In your example, there are two such nodes, and you always get both of them regardless of the context node (since the value you give is always 'a1'). When you ask for > <xsl:value-of select="$child/@value" /> You get the value of the node set, which is defined as the string value of the first node in the node set in document order. That's always the same node, the one with value='1', because the node set is always the same and document order doesn't change either. It's unclear why you are using the key. Why not just: <xsl:for-each select="CC"> <xsl:value-of select="DD/EE/@value" /> </xsl:for-each> ? Hope that helps, Wendell p.s. what's that namespace declaration xmlns="http://www.w3.org/TR/WD-xsl" doing for you anyhow? ><?xml version="1.0"?> ><AA> > <BB> > <CC> > <DD> > <EE aField="a1" value="1"/> > </DD> > </CC> > <CC> > <DD> > <EE aField="a1" value="2"/> > </DD> > </CC> > </BB> ></AA> > > ><?xml version="1.0"?> ><xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" > xmlns="http://www.w3.org/TR/WD-xsl" version="1.0"> > > <xsl:output method="text"/> > <xsl:key name="key-name" match="EE" use="@aField" /> > <xsl:template match="AA/BB"> > <xsl:for-each select="CC"> > <xsl:variable name="child" select="key('key-name', 'a1')" /> > <xsl:value-of select="$child/@value" /> > </xsl:for-each> > </xsl:template> > ></xsl:transform> ====================================================================== Wendell Piez mailto:wapiez@xxxxxxxxxxxxxxxx Mulberry Technologies, Inc. http://www.mulberrytech.com 17 West Jefferson Street Direct Phone: 301/315-9635 Suite 207 Phone: 301/315-9631 Rockville, MD 20850 Fax: 301/315-8285 ---------------------------------------------------------------------- Mulberry Technologies: A Consultancy Specializing in SGML and XML ====================================================================== XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
