>What is really odd about it is that a couple of times, I got valid return values, but otherwise, I get the error that you do. I noticed however that if you run it a bunch of times successively, the error changes in the line position. In other words, where it reports lineposition 293, it will also report anything from lineposition 291 through 303. I haven't found the flaw, but it just struck me as strange that the line position of the illegal xml character keeps changing. Also, that position seems to be in the 'definitions' line created by the compiler itself.

Alan,

This did help. I personally feel that it has something to do with the protocols being used. Namely, HTTP POST always works, SOAP doesn't.

Thanks again,
