Subject: [xsl] using xslt1 templates like dom methods, data overriding considerations From: "Luis A Ortiz" <luis@xxxxxxxxxxxxxxxx> Date: Thu, 25 Jan 2007 14:45:30 -0500 |
Hi List, I have an app I'm working on that contains a lot of xml formatted data. I am building in functionality so that this default content can be overridden without changing the default xml by writing the changes into a separate xml file. This [XSLT template] is simple enough for node deletion (omission) or updates because my override xml tags are explicit about this <removenode nodeid="123"/> and <updatenode nodeid="124">updated content</updatenode> but to include new nodes, and control where they are inserted, I want to use something like <insertnode nodeid="125" parentnodeid="123" position="last">new content</insertnode> or <insertnode nodeid="125" parentnodeid="123" position="first">new content</insertnode> or <insertnode nodeid="125" parentnodeid="123" insertbeforenodeid="456">new content</insertnode> <insertnode nodeid="125" parentnodeid="123" insertafternodeid="456">new content</insertnode> This is basically like the regular DOM methods, appendChild(), insertBefore() but I'm trying to do these with XSLT. The nodes that I want to insert relative to (after, before) may be being modified with update or remove templates. So my multi-part question is: can I do this in XSLT 1, MS .Net 1.1 (.net2 only if necessary) in the one transformation, or should this be a multiple transformations, or perhaps its better to do the insertions with DOM outside of XSLT (in aspx .net file, written in C#)? What is the best-practices approach to this type of design in general? I have tried searching for info on this pattern but haven't much discussion so far. I do have complete samples of what I have worked out thus far if it's useful: Source xml http://ndimensional.org/code/Lesson16-topic-4-wgeneratedids.xml Override xml http://ndimensional.org/code/Lesson16-topic-4-wgeneratedids-overrides-sepera teschema.xml XSL so far http://ndimensional.org/code/copysmart.xsl My current output http://ndimensional.org/code/part1output.xml Not sure if this is approp to ask here, since it affects many of my projects, I was wondering if anyone knows/wants to conjecture if/when MS will decide to support XSLT 2 in their server product? I read they had decided not to in favor of XQuery (2?) but were possibly revisiting that decision. I do realize that there exist excellent independently created processors (thanks Dr Kay) but often (so far) I've had to stick to MS 2003 out-of-the-box capabilities. Congrats and thank you to all the folks that worked so hard at getting us the 2.0 spec to Recommendation level! Best Regards, Luis Ortiz http://ndimensional.org
