Subject: [xsl] Testing a variable for node From: "rowan@xxxxxxxxxxxxxxxxxxxxx" <rowan@xxxxxxxxxxxxxxxxxxxxx> Date: Fri, 9 Oct 2009 08:50:52 -0400 |
How do I test a variable to see whether it contains a node, or something else (usually, in the case I'm working on, an empty string)? Everything I try causes an error if the variable contains a string. I have some code that will only work on nodes, and before calling this code I need to test and do something different if the variable doesn't contain a node.
