Answer 1

Hi Michael,

What is the type returned by the web method ? is it XmlDocument ? If yes, you can use OuterXml property of XmlDocument.

Because you say "read xml", I would suggest using XmlReader class to read your xml. If you want to run queries over your xml to extract data then your choose to use LINQ2XML which is implemented over XmlReader. See a comparison between LINQ2XML and XmlReader which will help you decide on the technology based on your requirements.

And here an example.

Hi. Thank you for respond. I am still looking  for full example to create xml in webservice and code for parsing. Here is my webmethod function

 

            If cls.GetData(col) Then     ' return 3 fields from sql server as a collection of custom class
                Dim sb As New StringBuilder()
                Dim writer As XmlWriter = XmlWriter.Create(sb)

                writer.WriteStartDocument()
                writer.WriteStartElement("Workers")

                For Each itm In col
                    writer.WriteStartElement("Worker")
                    writer.WriteAttributeString("Name", itm.FullName.ToString)
                    writer.WriteAttributeString("Ext", itm.Cell.ToString)
                    writer.WriteAttributeString("Photo", itm.Photo.ToString)
                    writer.WriteEndElement()
                Next

                writer.WriteEndDocument()
                writer.Flush()

                Dim xmlDocument As New XmlDocument()
                xmlDocument.LoadXml(sb.ToString())
                Return xmlDocument
           End If

 

Is it correct way to return XML?

I will appreciated for working example where my source xml is not stored file but webservice result

 

Thank you a lot

Hi Michael,

 

Welcome to the MSDN forum.

 

According to your description, I'm afraid it is a problem related to XML development in WebService. You may post thread in WCF, ASMX and other Web Services forum to get better support.

 

 

Thank you for your posting and understanding.

Have a nice day.
