HexaDecimal Error in XML Files

[danasegarane]

Hi all,
I am using this code to retrive the Viewsource content of page(Page content will be showed in XML).

It was working well. But now I face one problem , the XML contain any special hexadecimal value then it display an error

[PHP] Function GetXML(ByVal strTypeId As String) As String

Dim xmlRef As New MSXML2.XMLHTTPClass
Dim strUrl As String="Test.Asp"


Try
Console.WriteLine(strUrl.Trim)
xmlRef.open("GET", strUrl.Trim, False)
xmlRef.send()
GetXML = xmlRef.responseText
GetXMLDoc(-1)
'http://msdn2.microsoft.com/en-us/library/k1y7hyy9(vs.71).aspx
If xmlRef.statusText = "OK" Then
Return GetXML
Else
'Return GetXML = "False"
End If

Catch ex As Exception
'Return GetXML = "False"
End Try

End Function[/PHP]

Error : "'?', hexadecimal value 0xFFFF, is an invalid character."

Hw to solve this one

Thanks
Dana
