Amend XML

[JayWeb]

Hi,

I have the following XML document:

<?xml version="1.0" encoding="ISO-8859-1"?>
<MAP>
  <TILES>
    <TILE ID="1">
      <START>FALSE</START>
      <EXIT>FALSE</EXIT>
    </TILE>
    <TILE ID="2">
      <START>FALSE</START>
      <EXIT>FALSE</EXIT>
    </TILE>
    <TILE ID="3">
      <START>FALSE</START>
      <EXIT>FALSE</EXIT>
    </TILE>
  </TILES>
</MAP>

If I want to say search for a tile node with id attribute of 3 and change the START node to TRUE.

I have got this so far:

            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load("xmlfile.xml");
            XmlNode node = xmlDoc.SelectSingleNode("/MAP/TILES/TILE/START");
            node.Attributes[0].Value = "TRUE";
            xmlDoc.Save("xmlfile.xml");

But I have no idea how to find and change only the node with ID = 3.

Thanks

Jay

Found the answer.

XmlNodeList nodeList = xmlDoc.SelectNodes("/MAP/TILES/TILE[@ID='3']");
