Subject: Re: [xsl] relative . not working in complex xpath From: "mike@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Mon, 21 Jul 2014 11:00:52 -0000 |
"." within a predicate refers to the node that the predicate is being applied to, so the context item for ./xs:extension is the same as the context node for @name. If you're using XSLT you can often get arround this using the current() function. In pure XPath 1.0, join queries like this are difficult and not always possible. Switch to XPath 2.0 or XQuery if possible.
