[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Variable in XPath
 I hope that anyone can help me with the following. I want to write a stylesheet that is used to check if an element (class) with a special ID which is given as variable from the commandline exists in the source or not. If no variable is supplied I want to test if there are "class" nodes at all. Of course it's no problem to check if a node with a special ID exists or not. But what do I use as default value of the variable so that all "class" nodes are selected if no variable is supplied. (not working) example: XML: <facts> <class id="2" owner="1" name="A"/> <class id="3" owner="1" name="B"/> <facts> XSLT: <xsl:variable name="id" select="attribute::*"/> <xsl:template match="//condition/and-condition">
[...]
<xsl:when test="doc('factbase.xml')/facts/class[@id eq $id]">
[...]The test should be true if $id is set to "2" or "3" and if $id is not set at all. So, the key is the comparison "@id eq $id" and the default value of $id. "attribute::*" as default value is obviously wrong. Which default value do I have to use to test if class nodes exist at all? regards, Garvin
