Question

I have the following xml from a string:

<XMLClient>
  <ClientData>
   <Control type=1>BtnSave</control>
   <Control type=2>Suppliers.aspx</control>
   ...
   ...
   ...
  </clientData>
</XMLClient>

what I want to do is to return true or false using weather the record/node exists where the control’s type attribute is 2 and the text equals Suppliers.aspx.

I want to use linq for this, and I don’t know I guess I’m gonna need some linq expression, not quite sure…

Thanks in advance for any suggestions!

Something like this should work:

XDocument doc = XDocument.Load("test.xml");

bool nodeExists = doc.Descendants("Control")
                     .Where(x => x.Attribute("type") != null && 
                                 x.Attribute("type").Value == "2" && 
                                 x.Value == "Suppliers.aspx")
                     .Any();
