Subject: Re: [xsl] Concatenating multiple variables in a XPath statement From: "Mohsen Saboorian" <mohsens@xxxxxxxxx> Date: Tue, 20 Jun 2006 11:02:58 +0330 |
Thank you Micheal. There are xpath and element names in the variables. var1 contains an xpath like /form/body/rows/row[$i] and var2 has an element name which is found dynamically in a loop. I think this is the case that XPath does not support. Am I right?
You don't say what's in the variables.
If the variables hold element names, you can do
*[name()=$var1]/*[name()=$var2]
If the variables hold more than this, for example if they hold fragments of XPath like "@att" or "following-sibling::text()" then this approach doesn't work, you need to use an extension such as saxon:evaluate() which allows dynamic construction of XPath expressions.
