Subject: Re: [xsl] Matching attribute with condition in predicate|

I make two-pass transformation in my XSL using exsl:node-set (libxslt). ... <xsl:template match="tree"> <node attr="foo"/> </xsl:template> ... <xsl:template match="@attr[/root/@condition='ru']" mode="parse"> ... Last template should (i hope so) match my @attr 'cause it's more exact.
And it's working w/o predicate.
But it doesn't with.
Any thoughts why?
Because the "/" at the start of "/root/@condition" is the top of the _current tree_, not the top of the initial tree. Thus it is at the top of the tree with the attribute because it is in the predicate tested when the attribute is the current node.
... and then in your predicate @attr[$orig/root/@condition='ru'] in order to switch to the original tree from your temporary tree.
The note about "more exact" is that is too general a statement. Everything more complex than a simple name all have the same priority. The priority doesn't somehow steadily increase with more and more information.
So, yes, "@attr[$orig/root/@condition='ru']" has higher priority than "@attr" but it does not have higher priority than, say, "@attr[$orig/root/@condition='ru'][$orig/root/other1][$orig/root/other2]" which is at the same numeric level of priority of .5.
