Question

My XML looks like this:

<?xml version = "1.0" encoding = "utf-8"?>
<gallery>
  <name>Rosie's Gallery</name>
  <image>
    <order>0</order>
    <url>images/HappyIcon.jpg</url>
    <title>Happy</title>
  </image>
  <image>
    <order>1</order>
    <url>images/SickIcon.jpg</url>
    <title>Sick</title>
  </image>
</gallery>

If I have the url value available to me, how would I go about changing the corresponding title value? I’ve been trying to figure it out but I am hitting a road block.

Answer 1

XDocument xDoc = XDocument.Load(new StringReader(xmlstr));
string url="images/SickIcon.jpg";

var image = xDoc.Descendants("image")
                .Where(x => x.Element("url").Value == url)
                .First();
image.Element("title").Value = "Renamed Value";
