Subject: RE: [xsl] key() and document() - scoping problem? From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Tue, 19 Dec 2006 10:30:44 -0000 |
The key() function searches the document that contains the context node. In 1.0, you need to change the context node, which you can do using xsl:for-each. In 2.0, you can use the third argument of key() to determine which document is searched.
