Question

My XML looks like this:

<product id="1">
    <name>A thing</name>
    <description>This is what it's like</description>
</product>

I’ve been looking for an example that might look something like this:

string productID = 1;
XDocument productsXML = XDocument.Load("Products.xml");
for item in productsXML {
    if (item.ID == productID) {
        productNameLabel.Text = item.name;
    }
}

The idea being, I’ll be able to output a single xml child element to the .aspx page.

A thing

Does that make sense? I’ve been looking for examples for a few hours, and I’m starting to think that there is lot more scaffolding that I need, but since all the examples are so different, I’m not sure which one to follow!

So, how can I grab the contents of a single XML child element, and output it to the .aspx? Take this:

<product id="1">
    <name>A thing</name>
    <description>This is what it's like</description
</product>

and output this:

A thing

You can use XPath (in System.Xml.XPath)

string value = productsXML.XPathSelectElement("//product[@id='1']/name").Value;
