Question

Idea – List of vertices(Key, X, Y, Priority to store).

   <?xml version="1.0" encoding="utf-8"?>
   <Vertices>
    <Vertex Key="0" X="149" Y="209" Priority="7" />
    <Vertex Key="1" X="278" Y="128" Priority="7" />
   </Vertex>

Is this valid XML? It keeps saying me that root element is missing, when i try to open it… If so, can someone provide a valid c# XDocument code to open this file ?

Answer 1

It’s not valid XML – your closing element has the wrong name – this would be valid:

<?xml version="1.0" encoding="utf-8"?>
<Vertices>
  <Vertex Key="0" X="149" Y="209" Priority="7" />
  <Vertex Key="1" X="278" Y="128" Priority="7" />
</Vertices>

Also make sure that if you are loading an XML file you use XDocument.Load and not XDocument.Parse.
