Subject: [xsl] Tramsform XML through mapping schemas using XSL From: "Alistair Power" <Alistair.Power@xxxxxxxxx> Date: Wed, 27 Nov 2002 00:09:39 +0000 |
Hi, Just trying to work out whether I can transform xml by mapping schemas against each other using XSL, and thought I'd pick your brains for ideas/suggestions/be told that it's impossible and I'm a fool for even trying it :P My problem is that I have a simple valid xml (generated from a relational database which I don't have access to!), along with a corresponding schema A which it adheres to, and I want to transform it into a different slightly more nested xml document, which validates against schema B. Both schemas are different enough so that certain element values in the source schema A might become attribute values in schema B, and vica-versa. I know the exact mappings between the data in the source and target schema. What I ideally want to achieve is to store the mappings in a configuration xml file, and write a series of (generic?) XSL templates that get called based on iteration through the mapping file plus source xml file, and after a bit of magic output my target xml file, conformant to schema B. Now I could just write a straight transformation that took the source and transformed it, but I will be using different schemas in the future with different data and mappings, so wanted to try and approach this in a more generic fashion, with possible deference to the two schemas. So my questions are: 1. Do you think this is feasible through the use of just XSL? 2. Is it feasible to match nodes against data from a config file, and pass the resultant chosen node into a config defined transformation (say calling a specific template)? Apologies if the scenario description is a bit vague, but this is currently an idea in my head, and I am not sure whether this is something that would be better solved programatically with the support of XSL or through XSL alone. Thoughts/comments/ideas much appreciated... Thanks, Alistair Alistair Power alistair.power@xxxxxxxxx XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
