[xsl] treat attribute value as xpath expression

[Tjerk Wolterink]

I have xml like this:

<data>
<binding nodeset="/data/set1/value[@name='a']"/>
<set1>
<value name="a" value="3"/>
</set1>
</data>
is it possible with an xsl styelsheet to do something like this

<xsl:template match="binding">
<xsl:variable name="bounded-nodeset"
value="eval-xpath(./binding/@nodeset)"/>

</xsl:template>

Hope you understand what i mean.

Certainly not in XPath 1.0 as specified as a W3C recommendation. But
some processors provide extension functions for that, for example Saxon
6.5 has
<http://saxon.sourceforge.net/saxon6.5.5/extensions.html#evaluate>

EXSLT also has
<http://www.exslt.org/dyn/functions/evaluate/index.html> and lists
Xalan-Java, 4XSLT, and libxslt as supporting that.

A two-passes transformation can help, in some cases. The first pass
create a new stylesheet containing the XPath expression. The second
pass executes the created stylesheet.
