My purpose is to convert between different XSD/XML formats by
means of a mapping file generated from a database (i.e. a
reference data library), hence the data from the input file
shall be transformed to corresponding elements in the output
file according to defined criterias. The mapping file itself
can be constructed as needed from the db output.
So far it seems to be easiest to store the "full path"
(A/B/C) of the data elements in db, and map between them like:
<mappings>
<map>
<format_1>message/header/from</format_1>
<format_2>notification/originator</format_2>
</map>
How are you planning to handle namespaces?
I can see how you would use this to rename elements, if format_2 were a
simple element name. I can't see how you intend to use the full path in
format_2.
Q2: Are there better strategies / methods for solving this
kind of problem?
(Not limited to what's sketched above.)
I think that for this kind of problem, generating a stylesheet might be a
better approach than saxon:evaluate. It ends up being more extensible if you
want to add features like translating data values or grouping adjacent
values.
Come to my talk at XML 2006 next week on meta-stylesheets...
