New to Linq to Xml and having a play around with it. I am carrying out a lot of operations similar to 开发者_JAVA百科the following and I was wondering if it was possible in one statement:

I am carrying out a lot of operations similar to 开发者_JAVA百科the following and I was wondering if it was possible in one statement:

    Dim childXEl As XElement = _
    <ChildElement></ChildElement>

    Dim results = _
    From parentXEl In xdoc.Descendants.<ParentXElement> 

    For Each xe As XElement In results
        xe.Add(childXEl)
    Next

I doubt this is possible but I am curious to know, can you add the xml in the search query thus making the for each loop unnecessary?


Well List(Of T) has a ForEach method taking an Action you can can do stuff like this:

Sub Main()
    Dim doc As XDocument = _
    <?xml version="1.0"?>
    <root>
        <item>
            <foo>1</foo>
        </item>
        <item>
            <foo>2</foo>
        </item>
    </root>

    doc.Root.<item>.ToList().ForEach(AddressOf Add)
    doc.Save("output.xml")
End Sub

Sub Add(ByVal el As XElement)
    el.Add(<bar>test</bar>)
End Sub
