Subject: Re: [xsl] determine existence of preceding element From: David Carlisle <davidc@xxxxxxxxx> Date: Fri, 29 Oct 2004 14:38:17 +0100 |
what test will tell me if there are any preceding <text:p text:style-name="sub-module-title">s which follow the first preceding <text:p text:style-name="module-title"> of the currently visited <text:p text:style-name="sub-module-title">. preceding-sibling::text:p[@text:style-name="'module-title'][1] /following-sibling::text:p[@text:style-name="'sub-module-title'] is all the sub-module-titles following the previous module-title following-sibling::text:p[@text:style-name="'sub-module-title'] is all the sub-module-titles following the current node so one way to write your test is test="count(the first xpath above ) = count (the second xpath)" this isn't particularly efficient but unless you have thousands of nodes that probably doesn't matter. Altenatively you can express it as testing that the current node is in the node set returned by the first path, which you could write as test="count(the first xpath above ) = count (. | the first xpath above)" I suspect that really you want to do "positional grouping" which was discussed earlier this week, and is often most efficiently expressed using keys, but it depends a bit what transform you were doing that led to the above question.
