HI,

i am writing a epp client. which sends xml files to a server containing commands and i get a xml file back with a response.

below is the response i am getting, but i cannot read the xml with the "v" value in it and sometimes it is a W aswell, it looks like it has something to do with 32bit, but i have no idea

please assist me, with some vb.net code to read.under the xml is my reading xml code:

{ v<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<epp:epp xmlns:epp="urn:ietf:params:xml:ns:epp-1.0">
  <epp:response>
    <epp:result code="1000">
      <epp:msg>Access granted</epp:msg>
    </epp:result>
    <epp:trID>
      <epp:clTRID>#clTRID#</epp:clTRID>
      <epp:svTRID>COZA-EPP-13C2B6C9493-F8A4</epp:svTRID>
    </epp:trID>
  </epp:response>
</epp:epp>
}

    Private Function ParseResut(result As String) As Object
        Dim innerText As Object

if you get that "bad" xml, you have to solve that issue.
either on the send/response part, or otherwise just "remove" that trailing bad character before reading the xml

you should develop the "character" removal dynamically.
as the "true" xml string has to start with <?xml, remove everything before that.

change it as :

 Try
            Dim document As New XmlDocument()
            result = Regex.Replace(result, "^\{[^\<]+<", "{<")
            document.LoadXml(result)
