You may come across a situation when you will have to read a XML document containing name spaces and assign values to it. Here is sample which includes multiple namespaces with SOAP envelope xml document.
Test.XML
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<GetRecord xmlns="http://services.sample.com">
<Request xmlns:a="http://schemas.sample.com/2013/06/GetRecordRequest" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<LoginData>
<UserID>UserName</UserID>
<Password>password</Password>
<RequestID>23232323</RequestID>
<IPAddress>121.11.1.1</IPAddress>
</LoginData>
<a:RecordID>35488047</a:RecordID>
</Request>
</GetRecord>
</s:Body>
</s:Envelope>
Function which reads and assign values
Private Function ReadAndAssignRequestXML(ByVal recordID As String) As String
Dim xmlDoc As New XmlDocument
Dim InputSOAPXML As String = String.Empty
Dim xmlFileName As String = "C:\Test.xml"
Try
xmlDoc.Load(xmlFileName)
Dim nsmgr As XmlNamespaceManager = New XmlNamespaceManager(xmlDoc.NameTable)
nsmgr.AddNamespace("a", "http://schemas.sample.com/2013/06/GetRecordRequest")
nsmgr.AddNamespace("s", "http://schemas.xmlsoap.org/soap/envelope/")
nsmgr.AddNamespace("l", "http://services.sample.com")
xmlDoc.SelectSingleNode("/s:Envelope/s:Body/l:GetRecord/l:Request/l:LoginData/l:UserID", nsmgr).InnerText = "myUserID"
xmlDoc.SelectSingleNode("/s:Envelope/s:Body/l:GetRecord/l:Request/l:LoginData/l:Password", nsmgr).InnerText = "PASS"
xmlDoc.SelectSingleNode("/s:Envelope/s:Body/l:GetRecord/l:Request/a:RecordID", nsmgr).InnerText = recordID
InputSOAPXML = xmlDoc.OuterXml
Catch ex As Exception
InputSOAPXML = ex.Message
End Try
Return InputSOAPXML
End Function
