Mostly because that's the specific parser the implementation is written
for. SOAP requires reasonably elaborate namespace support, IIRC.

The VWXML parser shouldn't contaminate your image too badly :)

But it does point to it :)

	http://www.mars.dti.ne.jp/~umejava/smalltalk/soapOpera/index.html	

has links and implementation instructions.

If it's really very specific, I'd say just hack it. By very specific I
mean you pretty much know what methods you want to call and what kinds of
answers you're getting back.

I have a friend who claims that there's a clear SOAP subset that's roughly
equivalent to XML-RPC (as there should be :)), at least in the sense that
it's a reasonable one person one weekend project. My impressions of SOAP
overall, though, is that it can get somewhat hairy.

FWIW, I just downloaded SoapOpera 0.2a. My quick scan of the code makes me
think that's it's pretty reasonable to play with.

Well, I loaded it into a current ComSwiki image and there's some
brokenness due to changes in ComSwiki.

Well, that's a bit of a bummer.

Hope this helps.

Though I don't see why it would :)
