If your code litteraly includes the
a href
then the uri is indeed invalid. Might also be a mistake when creating this question. In that case please edit this question and let me know. I will then remove this answer.
oXmlDocument.Load("<a href="http:
You cannot simply open an URL as if it was a local file. The webserver simply won't accept it. You first need to create the xml (file) and then upload it to the url. Change your code so it writes the xml to an actual file (for example: c:\temp\MobileBookingRequest.xml)
Then after you are done and called
xmlWriter.Close();
try this:
WebClient client = new WebClient();
client.UploadFile("http://impertosolutions.somee.com/MobileAPI_XML/MobileBookingRequest.xml", "c:\temp\MobileBookingRequest.xml");
Good luck!
