Subject: [xsl] xslt 2.0: grouping flat element structures to make lists From: "Derek Revill" <derek@xxxxxxxxxxxxxxxxxx> Date: Wed, 25 May 2005 19:07:14 +0100 |
Hello Using XSLT 2.0 (running Saxon 8.4) I am grappling with a pretty standard grouping issue, attempting to utilize some of XSLT v2 grouping possibilities but with no success (reading the W3C spec and a scan of the archive haven't proved helpful, MK book is on order!). Mid flow I have: .. .. <par class="Listbegin">Fruit</par> <par class="Listitem>Apple</par> <par class="Listitem>Orange</par> <par class="Listitem>Pear</par> <par class="Listbegin">Colours</par> <par class="Listitem>Red</par> <par class="Listitem>Green</par> <par class="Listitem>Blue</par> .. .. I just need to output .. .. <list> <head>Fruit</head> <item>Apple</item> <item>Orange</item> <item>Pear</item> </list> <list> <head>Colours</head> <item>Red</item> <item>Green</item> <item>Blue</item> </list> Note: I'm midway through processing any section when I encounter the <par class="Listbegin">. The signal that a list has ended can be any following-sibling that isn't <par class="Listitem>..</par> or the end of the parent element I'm in. Of course, lists don't always come in pairs like above. Should I try to match on the <par class="Listbegin"> then scoop-up all relevant following nodes, which was my strategy up to now? Haven't been able to find a way to scoop-up only the following nodes that are relevant. Any advice gratefully received. Numerous attempts using for-each-group and various group-by strategies have been fruitless, probably I just haven't quite grasped it! Thanks Derek Revill
