How to retrieve data from XML using LINQ in VB.NET?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I cannot find a way to get the values from an XML file using LINQ.
Here is the code:
Dim XMLDoc As XDocument = XDocument.Load(XMLPath)
Dim query = From ex In XMLDoc.Descendants.Elements("DSServer")
Select New With
{
.svrname = ex.Element("ServerName"),
.BG = ex.Element("IsBG")
}
For Each t In query
MsgBox(t.svrname.Value.ToString + " " + t.BG.Value.ToString)
Next
And here is the XML
<?xml version="1.0" standalone="yes"?>
<DSPaths xmlns="http://tempuri.org/DSPaths.xsd">
<DSServer>
<ServerName>test1Name</ServerName>
<ServerIP>test1</ServerIP>
<ServerPath>test1</ServerPath>
<Destination>test1</Destination>
<IsBG>true</IsBG>
</DSServer>
<DSServer>
<ServerName>test2Name</ServerName>
<ServerIP>test2</ServerIP>
<ServerPath>test2</ServerPath>
<Destination>test2</Destination>
<IsBG>true</IsBG>
</DSServer>
</DSPaths>
What am I doing wrong?
The code does not return anything...

I would assume that XMLDoc.Descendants.Elements("DSServer") doesn't return any value. So the problem should be before any LINQ. Have you tried removing (in the xml) or specifying (in the code) the namespace?

How can i do to specify the namespace? I tried removing the namespace in the XML file and it now works... but the thing is that my code writes the using an XSD file, so it enters the namespace in the XML.

If you can't remove the namespace from the xml, you'll need to specify the namespace in the query.
Dim ns As XNamespace = "http://tempuri.org/DSPaths.xsd"
Dim query = From ex In XMLDoc.Descendants.Elements(ns + "DSServer")
Select New With
{
.svrname = ex.Element(ns + "ServerName"),
.BG = ex.Element(ns + "IsBG")
}

If you can't remove the namespace from the xml, you'll need to specify the namespace in the query.
Dim ns As XNamespace = "http://tempuri.org/DSPaths.xsd"
Dim query = From ex In XMLDoc.Descendants.Elements(ns + "DSServer")
Select New With
{
.svrname = ex.Element(ns + "ServerName"),
.BG = ex.Element(ns + "IsBG")
}
