Answer 2

Possible enhancement... I found, with my situation (and this was in the soap response, btw, in case it matters), that if the resulting request is shorter than the original (and in your case it is), there was crud left over when the new string is written back out to the stream.
ex:

original: <blablaa some stuff>
intended: <bla some stuff>
actual:   <bla some stuff>uff>

Fix:

SOAPRequest.Postion:=0;// i forget this here, as i write the code that worked
SOAPRequest.size := length(sTmp.Text); // Important - set new length before saving.
sTmp.SaveToStream(SOAPRequest);
