Subject: RE: [xsl] Testing for a following sibling node type that occurs at a varied position From: "Wright, Steve" <Steve.Wright@xxxxxx> Date: Wed, 30 Jun 2004 12:13:29 -0400 |
Hi Wendell, Thanks for taking a stab at this, and if I hadn't oversimplified my example XML, your solution would be perfect - however, it still needs a little tweaking, but I think we are very close. The problem is that the 'B' nodes are not sequential as I had indicated in my example, they have lot's of other variable sibling nodes sprinkled in between them, so your test is returning true for each 'B' node since none of them have another 'B' directly following and they all have a following 'A'. The logic that should work would be something like: test="following-sibling::*[any number before the next 'A'][not(self::B)] and following-sibling::A" Can you think of a sanctioned way to implement this? Thanks again for all of your help.

As I recall, Mike suggested child::A/preceding-sibling::B[1], which isn't considered adequate because the context node is already a B, not the parent of the As and Bs. So the requirement is not to *select* all B nodes that have no Bs after them before As, but to test true on a B context node that is (as the OP said) "the last 'B' node that occurs before the next 'A' node". In other words, the context node is a B, and the test should detect that the directly following sibling is not a B, but that there is an A following sibling. This is test="following-sibling::*[1][not(self::B)] and following-sibling::A" Cheers, Wendell ====================================================================== Wendell Piez mailto:wapiez@xxxxxxxxxxxxxxxx Mulberry Technologies, Inc. http://www.mulberrytech.com 17 West Jefferson Street Direct Phone: 301/315-9635 Suite 207 Phone: 301/315-9631 Rockville, MD 20850 Fax: 301/315-8285 ---------------------------------------------------------------------- Mulberry Technologies: A Consultancy Specializing in SGML and XML ====================================================================== --+------------------------------------------------------------------ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list To unsubscribe, go to: http://lists.mulberrytech.com/xsl-list/ or e-mail: <mailto:xsl-list-unsubscribe@xxxxxxxxxxxxxxxxxxxxxx> --+-- **************************************************************************** This email may contain confidential material.
