Re: [xslt] scope of variables

[<Nicholas_Liebmann McAfee com>]

I'm not sure if it is legal XSLT, nor whether it works in newer versions of libxslt, but to solve this problem, I use the EXSLT function extension

e.g
<xsl:variable name="x" select="'x'"/>

<func:function name="matchFunc">
   <xsl:param name="arg"/>

    <func:result select="$arg = $x"/>

</func:function>

<xsl:template match="x[matchFunc(@name)]">
<xsl:message>@name is <xsl:value-of select="$x"/></xsl:message>
</xsl:template>

<xsl:template match="x[not(matchFunc(@name))]">
<xsl:message>@name is NOT <xsl:value-of select="$x"/></xsl:message>
</xsl:template>

NOTE: You will need to set your stylesheet version to 1.1, and add the requisite namespace/extenstion declarations

Regards

Nick

It is an error for the value of the match attribute to contain a
VariableReference.
