I have an xml file, that consists of the following structure.

<XtraSerializer version="1.0" application="PivotGridControl">
<property name="#LayoutVersion" isnull="true" />
<property name="$PivotGridControl" iskey="true" value="PivotGridControl">
<property name="Fields" iskey="true" value="41">
<property name="Item1" isnull="true" iskey="true">
<property name="AreaIndex">0</property>
<property name="Name">fieldCode</property>
<property name="Area">RowArea</property>
<property name="FilterValues" isnull="true" iskey="true">
<property name="DeferFilterString" />
<property name="ValuesCore" iskey="true" value="0" />
<property name="Values">~Xtra#Array0, </property>
<property name="ShowBlanks">true</property>
<property name="FilterType">Excluded</property>
</property>
</property>
<property name="Item2" isnull="true" iskey="true">
<property name="AreaIndex">1</property>
<property name="Name">fieldGroup</property>
<property name="Area">RowArea</property>
<property name="FilterValues" isnull="true" iskey="true">
<property name="DeferFilterString" />
<property name="ValuesCore" iskey="true" value="0" />
<property name="Values">~Xtra#Array0, </property>
<property name="ShowBlanks">true</property>
<property name="FilterType">Excluded</property>
</property>
</property>
<property name="Item3" isnull="true" iskey="true">
<property name="AreaIndex">2</property>
<property name="Name">fieldProduct</property>
<property name="Area">ColumnArea</property>
<property name="FilterValues" isnull="true" iskey="true">
<property name="DeferFilterString" />
<property name="ValuesCore" iskey="true" value="0" />
<property name="Values">~Xtra#Array0, </property>
<property name="ShowBlanks">true</property>
<property name="FilterType">Excluded</property>
</property>
</property>
</property>
</XtraSerializer>

I need to loop through all the Items under the element Fields and get the Name and Area attribtutes for each Item
Basically loop through this node
<property name="Fields" iskey="true" value="41">

Hi countrymeister;

The following is using Linq to XML to return the property nodes who's attributes are either name="Name" or name="Area"

// If the XML document is stored on the file system use this line and replace the file path with the one that points to the loction and name of yours.
XDocument doc = XDocument.Load("C:/Working Directory/XtraSerializer.xml");
// Or use this line if the XML is stored in a string in your program replacing VariableNameHere with the actual variable name hollding the XML.
XDocument doc = XDocument.Parse(VariableNameHere);

var results = from nodes in doc.Descendants("property")
              where nodes.Attribute("name").Value == "Fields"
              from node in nodes.Elements("property").Descendants("property")
              where node.Attribute("name").Value == "Name" || node.Attribute("name").Value == "Area"
              select node;
