I’ve got an XML file that looks like this: … <body> <unit id=1 name

  • 0

I’ve got an XML file that looks like this:

...
<body>

<unit id="1" name ="xxx">
<sourceFile>SomeFile.xml</sourceFile>
<targetFile/>
</unit>

<unit id="2" name ="xxx">
<sourceFile>SomeFile.xml</sourceFile>
<targetFile/>
</unit>

</body>

Can someone show me how I would use LINQ to XML via C# to read the value of the sourceFile node, and update the value of targetFile as I’m not familiar with LINQ to XML?

Thanks.

    Something like this:

    XDocument doc = XDocument.Load("file.xml");
foreach (var sourceNode in doc.Descendants("sourceFile"))
{
    XElement targetNode = sourceNode.Parent.Element("targetFile");
    if (targetNode != null)
    {
        targetNode.Value = sourceNode.Value;
    }
}

    Alternatively:

    XDocument doc = XDocument.Load("file.xml");
foreach (var unitNode in doc.Descendants("unit"))
{
    XElement sourceNode = unitNode.Element("sourceFile");
    XElement targetNode = unitNode.Element("targetFile");
    if (sourceNode != null && targetNode != null)
    {
        targetNode.Value = sourceNode.Value;
    }
}

    (And call doc.Save afterwards if you want to save back to a file, of course, as pointed out in another answer.)
