Question

How could I query an xml file, like the one below, with C# .NET 2.0? I have the id value and need to get the thumbnail image related to that id.

<root>
    <categories>
        <category title="decking">
            <photos>
                <photo id="1" smallphoto="/files/images/photogallery/thumbs/EarthwoodEvolutions1_thumb.jpg"  />
                <photo id="2" smallphoto="/files/images/photo-gallery/thumbs/XLM401_thumb.jpg"  />
            </photos>
        </category>
    </categories>
</root>

You can use XmlDocument

And look up the desired nodes using xpaths.

For your case something like:

root/categories/category/photos/photo[@id='1']
