Hi DLH,
I had a similar problem a couple of months ago trying to return an XML
string from a file upload servlet in IE. In my case IE appeared to be
consuming the first 20/30 chars of the XML text before my
onSubmitComplete() could get its hands on it thus rendering it un-
parsable. I went through just about every tip on the group relating to
this in various combination ("text/html" is definitely right, but
still didn't work for me) for a frustrating day to no avail. I came to
the conclusion that IE was trying to be "helpful" by interpreting the
markup itself and screwing it up rather than just leaving it alone. I
imagine there is a way to get round this but it is not clear to me
what. As you can see, this is a different but related problem to
yours, which suggests that IE can be awkward and unpredictable with
XML responses.
Next morning I decided to learn JSON, which I had never used before,
and between the simple flexjson lib and GWT JSON parser I had it
working within a couple of hours and was delighted to see that IE
completely ignored the JSON return strings in all cases. Personally I
will not bother with XML again.
Unfortunately JSON doesn't sound like a solution for you, and I'm
sorry I don't have the "real" answer. One thing that might work if all
else fails is to put your XML inside a JSON response as a single text
field, dig it out using the GWT JSON parser, then use the GWT XML
parser on it. Horrible I know, but it will probably stop IE
interfering with your response.
regards
gregor
