I have a variable /blade/elementlink that contains data of a /blade/data tag now i would like to check if the tag /blade/data element exist in my document.
So when there exist a /blade/data tag with "some tag info" i want the XSL to print yes otherwise no.

My example code.
XML:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="xslData.xsl"?>
<blade>
<elementlink>/blade/data</elementlink>
<data>some tag info</data>
</blade>

XSL:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">

<xsl:variable name="var1" select="/blade/elementlink" />

<xsl:template match="/">
<p>test : </p>
<xsl:value-of select="$var1"/>
<xsl:choose>
<xsl:when test="$var1">
<xsl:text>Yes</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text>No</xsl:text>
</xsl:otherwise>
</xsl:choose>
</xsl:template>

</xsl:stylesheet>

You can't do that.

Match expressions must be literals, not expressions.

Typically this is handled with xsl:choose blocks.
