Subject: Re: [xsl] Extracting a list of unique base urls from anchors in a html docu ment. From: David Carlisle <davidc@xxxxxxxxx> Date: Thu, 13 Sep 2001 17:45:24 +0100 |
> The second predicate should (I think) limit the returned node-set to contain > only anchors that have a href attribute that has a unique base-url No as [not(substring-before(@href,'#')=substring-before(preceding::a/@href,'#'))] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ this takes the string value of the node set which is the string value of the first node, so that only tests the current href attribute with the first href attribute in the document, not with all the preceding ones. This is really a grouping broblem see th egrouping techniques at Jeni's site. Basically you want to construct a key that uses match="a[contains(@href,'#')" use="substring-before(@href,'#')" then using key() you can get hold of all the links with the same base.
