 This is my first post to this list and I apologize for it's length. My question basically is whether it is possible to create a key on a variable which contains the result of applying a template? In my real stylesheet and xml the template which creates the node-set I would like to create the key on is much more complicated than the example I have given below - but the concept is the same. I apply-templates to the source document and the result tree fragment is kept in a variable ($alphabet). I convert this to a node-set ($alphabet-exslNodeSet) and then use that node-set in another template. It works but is pretty slow - I think it would be much faster if I were able to create a key on the node-set (each item in the node set is used multiple times). I can't see how to do that - it looks like my attempt below gives me the code in the variable, not the result. I know I can't use a variable in the key's match attribute, so I'm at a loss how to do this. Thanks for any suggestions, Grainne. The Stylesheet: ============ <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" xmlns:saxon="http://icl.com/saxon" xmlns:exsl="http://exslt.org/common" exclude-result-prefixes="ss" extension-element-prefixes="exsl saxon"> <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/> <xsl:variable name="alphabet"> <xsl:apply-templates select="/test/alphabetList/alphabet" mode="loadList"/> </xsl:variable> <xsl:variable name="alphabet-NodeSet" select="document('')/xsl:stylesheet/xsl:variable[@name='alphabet']" /> <xsl:variable name="alphabet-exslNodeSet" select="exsl:node-set($alphabet)"/> <xsl:key name="myKey" match="/*/xsl:variable[@name='alphabet']" use="@col"/> <xsl:template match="alphabet" mode="loadList"> <xsl:copy-of select="."/> </xsl:template> <xsl:template match="*"/> <xsl:template match="/"> Value of alphabet variable is:<xsl:text> </xsl:text> <xsl:copy-of select="$alphabet"/><xsl:text> </xsl:text> Value of alphabet-NodeSet varaible is (I think this is what I get in the key!!)<xsl:text> </xsl:text><xsl:copy-of select="$alphabet-NodeSet"/><xsl:text> </xsl:text> Value of alphabet-exslNodeSet variable is <xsl:text> </xsl:text><xsl:copy-of select="$alphabet-exslNodeSet"/> <xsl:text> </xsl:text> <xsl:apply-templates select="test/numbers"/> </xsl:template> <xsl:template match="numbers"> <xsl:for-each select="number"> <xsl:variable name="curPosition" select="position()"/> Using the key to get the alphabet element (THIS is what I'd like to do since each node in the set is used multiple times): <number value="{.}"> <xsl:for-each select="document('')"> <xsl:copy-of select="key('myKey',$curPosition)"/> </xsl:for-each> </number> Using the exslNodeSet variable to get the alphabet element (what I am doing but which is very slow in my real code): <number value="{.}"> <xsl:copy-of select="$alphabet-exslNodeSet/alphabet[@col=$curPosition]"/> </number> <xsl:text> </xsl:text> </xsl:for-each> </xsl:template> </xsl:stylesheet> Example xml: ========== <?xml version="1.0" encoding="UTF-8"?> <test> <alphabetList> <alphabet col="1">a</alphabet> <alphabet col="2">b</alphabet> <alphabet col="3">c</alphabet> <alphabet col="4">d</alphabet> <alphabet col="5">e</alphabet> </alphabetList> <numbers> <number>one</number> <number>two</number> <number>three</number> <number>four</number> <number>five</number> </numbers> </test> Result (tidied up a little): ==================== <?xml version="1.0" encoding="UTF-8"?> Value of alphabet variable is: <alphabet col="1">a</alphabet> <alphabet col="2">b</alphabet> <alphabet col="3">c</alphabet> <alphabet col="4">d</alphabet> <alphabet col="5">e</alphabet> Value of alphabet-NodeSet varaible is (I think this is what I get in the key!!) <xsl:variable xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" xmlns:saxon="http://icl.com/saxon" xmlns:exsl="http://exslt.org/common" name="alphabet"> <xsl:apply-templates select="/test/alphabetList/alphabet" mode="loadList"/> </xsl:variable> Value of alphabet-exslNodeSet variable is <alphabet col="1">a</alphabet> <alphabet col="2">b</alphabet> <alphabet col="3">c</alphabet> <alphabet col="4">d</alphabet> <alphabet col="5">e</alphabet> Using the key to get the alphabet element (THIS is what I'd like to do since each node in the set is used multiple times): <number value="one"/> Using the exslNodeSet variable to get the alphabet element (what I am doing but which is very slow in my real code): <number value="one"> <alphabet col="1">a</alphabet> </number> ...<snip>...
