I have what I think should be a very easy problem to solve but the
solution eludes me.
I have a simple stylesheet that attempts to lookup a value using the xsl:key tag and key() functions. I can easily get this to work if the lookup table is in a file and read it in using the 'document()' function, as follows: <xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:exsl="http://exslt.org/common"
extension-element-prefixes="exsl"
>
<xsl:variable name="lookupDoc" select="document('lookup.xml')" />
<xsl:key name="lookupKey" match="entry" use="@key"/>
<xsl:template match="dataList/data">
<xsl:variable name="dataKey" select="."/>
data key: <xsl:value-of select="$dataKey" /><xsl:for-each select="$lookupDoc" > lookup entry value: <xsl:value-of select="key('lookupKey', $dataKey)"/> </xsl:for-each> </xsl:template> </xsl:stylesheet> The lookup.xml file: <entries> <entry key="key1">lookup entry 1</entry> <entry key="key2">lookup entry 2</entry> <entry key="key3">lookup entry 3</entry> </entries> The source document to be translated: <dataList> <data>key2</data> <data>key1</data> </dataList> Output from this follows (correct): data key: key2
lookup entry value: lookup entry 2 data key: key1
lookup entry value: lookup entry 1However, I want to my 'lookupDoc' to be derived from a parameter or variable, ideally passed down to the stylesheet as a global parameter. Sort of as follows: <xsl:variable name="lookupRTF"> <entries> <entry key="key1">lookup entry 1</entry> <entry key="key2">lookup entry 2</entry> <entry key="key3">lookup entry 3</entry> </entries> </xsl:variable> <xsl:variable name="lookupDoc" select="exsl:node-set($lookupRTF)" /> everything else is the same in the stylesheet. When I run this, the key() function cannot find the key in my lookup doc... Output follows: data key: key2
lookup entry value: data key: key1
lookup entry value:I'm stumped.....
