Hello,
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[(_at_)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
