XML/XSD Default values - 20 June 2007

Hi,
I'm new to XML, XSD and XSLT.
I was wondering if there is a way to "fill out" an XML document with its default values, as if "expanded" so that my XSLT processor could use these defaults in generating the output.
I think if I had a schema-aware XSLT processor (SAXON-SA), then I could get this done easily as the transformation would be done against an XML document validated against an XSD.
That is not an option for my company for various reasons.
Is there a 2-stage process I can execute (in Java SAX/DOM?) that will "fill out" the required default values for elements or attributes?
I see there are validator classes, but none of these allow me to "write back" the resultant XML(with defaults populated) so that I may use the "expanded" form in subsequent processing.
Thanks,
|

Hello sauronlord,
I'm facing the same problem as you.
Actually I need to do a filling tool from an xsd file with very few time for this.
This tool must fill an existing xml file with all the mandatory elements that are not
already filled.
I wonder why it's so difficult to find a solution for this.
If this "default" attribute exists, it should be used for something...????
Maybe you have found a way to do it?
Thanks in advance

Hi,
Sorry it took me so long to get back. I was just searching for this question again and my post came up and it took me a moment to realize it was me!
I have not found out how to do it with XSLT (without using SAXON-SA). I believe that will work however.
Another way might be to walk through the XML document programmatically and check if a default exists and then populate it. However this cumbersome and I tried to stay away. The problem sort of "went away" on itself at work because we ended up doing something slightly different--- however now on a different project it is coming back up :)
If I find anything I'll try to post back here, but I imagine it won't be for maybe a month or two before I get results.
Right now I am looking at Code Synthesis XSD for XML->C++ object data binding, and it shows some promise for other things and hopefully it has a mechanism for "filling out" defaults.
good luck,
