Re: [xsl] dynamic variable name/implementation question

["Nathan Young" <natyoung@xxxxxxxxx>]

Ooops, sorry I was unclear.

I interpreted the path OP had gone down was something like:

<xsl:stylesheet>
	<xsl:param name="p1"/>
	<xsl:param name="p2"/>
	<xsl:param name="p3"/>
	...

in which case the template match could look like:

<xsl:template match="external-vaue">
	<xsl:choose>
		<xsl:when test="@parameter = 'someParam'">
		    <xsl:value-of select="$p1"/>
		</xsl:when>
		<xsl:when test="@parameter = 'someOtherParam'">
		    <xsl:value-of select="$p2"/>
		</xsl:when>
	</xsl:choose>
</xsl:template>

I understand the value of getting a nodeset instead.  We use that  
technique to embed terms in the XML that get localized using an xsl and  
xml dictionary file.  Simplified:

<xsl:stylesheet>
	<xsl:param name="language" select="'en'"/>
	<xsl:param name="country" select="'US'"/>
	<xsl:param name="dictName"/>
	<xsl:variable name="dictionary" select="document($dictName)"/>

	<xsl:template match="/ | @* | node()">
		<xsl:copy>
			<xsl:apply-templates select="@* | node()"/>
		</xsl:copy>
	</xsl:template>

	<xsl:template match="translateterm">
		<xsl:variable name="keyToFind" select="@key"/>
		<xsl:value-of  
select="$dictionary/dictionary/bundle[@language=$language]/bundle[@country=$country]/translateterm[@key=$keyToFind]"/>
	</xsl:template>
	
</xsl:stylesheet>
