Subject: RE: [xsl] [XSL] Calculating Length of String Variables From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Thu, 13 Sep 2007 08:29:51 +0100 |
Firstly, don't use this construction: <xsl:variable name="image_src"> <xsl:value-of select="./@url"/> </xsl:variable> Instead, write: <xsl:variable name="image_src" select="./@url"/> That's nothing to do with this problem but it's a bad and very common coding habit that you should try to break. If the variable is a global variable, as you seem to be suggesting, then "." is the root (document) node, and document nodes don't have any attributes. If your XML only contains the one element you showed, then you should do select="/graphic/@url".
