Sending xml content in body paragraph

[Vasile]

Hi,

I need to send the content of an xml file in the body part of a message, using the POST method.
The requirement is to specify Content-Type=application/xml in the header part.

Question:   Can this be done with the method:

.NavigateWithWebResourceRequest(String uri, String method,  String postData,  String headers)

or

.PostWebMessageAsString(String webMessageAsString)

A small example would help.

Thanks you,
Vasile
