Locating data in my XML file using C#

Question

Hi !
I have a XML file. Here is a snippet:
<Layers Count="9">
<Layer Name="layer0" Type="Polygon">
<OverlapNames Count="2">
<OverlapName Name="layer1"/>
<OverlapName Name="layer2"/>
</OverlapNames>
<CommonNames Count="0">
</CommonNames>
<SnapNames Count="1">
<SnapName Name="layer3"/>
</SnapNames>
</Layer>
Now, if I have a "layer" is there a quick way to find the node "Layer" that name a name "layer0".
Secondly, is there a way to not only locate the node but return true if the "type" is a certain value? In the above example layer0 is a polygon. So if I encounter a point entity on layer0 and I try to find a layer where name="layer0"
and type="point" it should return empty.
Thanks for clarification on right way to parse the XML data file to locate the information I need.

Answer 1

strQuery = String.Format("Layers/Layer[@Name=\"{0}\"]", pEntPoly3D.layer());
XmlNode nodeLayer = xmlOrbis.SelectSingleNode(strQuery);
if (nodeLayer == null)
And:
Layers/Layer[@Name=\"{0}\" and @Type=\"{1}\"]",
