Hello

I'd like to match a dynamic node, given as a parameter to the
stylesheet. Something like:

<xsl:stylesheet ...>
<xsl:param name="tomatch"/>
<xsl:template match="{$tomatch}">
Hallo
</xsl:template>
</xsl:stylesheet>

However, this seems not to be so simple, as "{" and if I remove the
parentesis the "$" are not allowed in the match value.

Certainly, I could take this as a row xslt and pre-transform it with
another script to merge the value of the variable into the {$tomatch}
location. However, then I would need two steps, one to create the
merged xslt, and another to transform the xml with it.

Is there a way to get it simlier? Any idea how to match dynamic nodes
given in parameters would be highly appreciated.

Thanks in advance.

Daniel,

I would approach the problem in a different way, see the attached solution

The stylesheet has two global parameters one to match the element local name one for the namespace URI. If your document does not use namespaces just pass the element name.

Hope this helps

Does this work also with whole path expressions like /Service/Data/Response?

XSLT is not designed to parse/evaluate XPath at run-time.

Some processors implement an extension function for this purpose, for example Saxon:evaluate.
