Why XDocument can’t get element out of this wellform XML text?

I’m trying to read an xml using linq to xml, and i guess i’m understanding something wrong.
This is the start of the xml (it’s long so i’m not posting it all)

<?xml version="1.0" encoding="utf-8"?>
   <Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">
      <Body>
         <ReportItems>
             <Tablix Name="Tablix12">
              ......
              ......
             </Tablix>

This xml could have a few of “Tablix” elements, and might have 1 or none, for each one of these i want to read whats inside this tag and i’m having difficulty to start.

I have tried a few ways to get the “Tablix” elements, or any other element.
In this code i get a result only for the “var root”, the rest of them are always null and i don’t understand what i’m doing wrong.

    public ReadTablixResponse ReadTablixAdvanced(string rdl)
    {
        XDocument xml = XDocument.Parse(rdl);

        var root = xml.Root;
        var Body = xml.Root.Element("Body");
        var report = xml.Root.Element("Report");
        var aa = xml.Element("Report");
        var bb = xml.Element("Body");
        var test = xml.Elements("Tablix");

    One thing i noticed, is that you used the method Element("name"). which will always try to retrun the first (in document order) direct child element with the specified XName . and that is probebly why you got null.

    if you want to return deeper elements(from where you looking). you need to use the Descendants(“name”) method, which will return a collection of all descendants elements . no matter how deep they are (relative to your chosen anchor)…

    for example:

     XNamespace xNameSpace = "http://schemas.micro.....";
 // ...
 var tablixes= xml.Descendants(xNameSpace + "Tablix");

    which you can then wolk through:

    foreach (var tablix in tablixes)
{
    var name=(string)tablix.Attribute("Name");
    var age=(int)tablix.Element("age");
   ...

}
