Subject: [xsl] preceding-sibling after sort gives unexpected result From: Kaine Varley <kaine.varley@xxxxxxxxxxxx> Date: Thu, 11 Sep 2003 18:03:26 +0100 |
Hi, I am trying to process a document similar to the one below, using the stylesheet below. My problem is that after I have performed the sort, I appear to get the preceding sibling in the original document order rather than in the newly sorted order. Looking at the results, you can see that for result number 4, I was hoping to get (a) as my preceding sibling, and not (c), which was the original document order. This is an unexpected result, and not at all what I was hoping for. Is this supposed to happen, or is this just a quirk of MSXML?
