Read XML in VB.net

Question

I have googled for the last hour or so with no luck (I\'d like to think I\'m a great googler too!), so here I am.

I have an XML file that I\'m using for my programs sett

Answer 1

Ah, a perfect example for showing off the powerful XML features of VB.NET with Framework 3.5:

Sub Main()
    Dim xml = XDocument.Load("config.xml")
    Console.WriteLine("Number: " & xml.<config>.<store>.<number>.Value)
    Console.WriteLine("Body: " & xml.<config>.<emailsettings>.<emailbody>.Value)
End Sub

yields:

Number: 0323
Body: package received

Here's a Console app using the VB.Net XML Literal support.

Module Module1

    Sub Main()

        Dim xElem = <config>
                       <store>
                           <number>0323</number>
                           <address>address</address>
                           <phone>phone</phone>
                       </store>

                       <emailsettings>
                           <emailfrom>emailfrom</emailfrom>
                           <emailpass>pass</emailpass>
                           <emailsubject>received</emailsubject>
                           <smtpserver>smtp.gmail.com</smtpserver>
                           <smtpport>587</smtpport>
                           <enablessl>true</enablessl>
                           <emailbody>package received</emailbody>
                       </emailsettings>
                       <dbconfig>
                           <dbpath>path</dbpath>
                       </dbconfig>
                   </config>

        Dim number = xElem.<store>.<number>.Value
        Dim emailbody = xElem.<emailsettings>.<emailbody>.Value

        Console.WriteLine(String.Format("Number={0}", number))
        Console.WriteLine(String.Format("emailbody={0}", emailbody))
        Console.ReadLine()

        '--- What it'd look like if you loaded from a file using XDocument.Load
        Dim xDoc = XDocument.Load(New IO.StringReader(xElem.ToString))
        number = xDoc.Root.<store>.<number>.Value
        emailbody = xDoc.Root.<emailsettings>.<emailbody>.Value

        Console.WriteLine(String.Format("Number={0}", number))
        Console.WriteLine(String.Format("emailbody={0}", emailbody))
        Console.ReadLine()


    End Sub

End Module

The results will be:

Number=0323
emailbody=package received

Number=0323
emailbody=package received

You can use XML Serialization. Create classes that represent your XML structure and use the XML Serialization Class to deserialize the data. Once you have done that you can use the data in your application.

Below is a link to an example from MSDN:

If you are familiar with datasets and datatables, this is an easy way to do it:

Dim DS As New DataSet
DS.ReadXml("Data.xml")

DataSets can read any XML. I even use this to call rest-enabled XML services.
