Question

This is the response I’ll be getting:

<?xml version="1.0" encoding="utf-8"?>
<rsp stat="ok">
        <image_hash>cxmHM</image_hash>
        <delete_hash>NNy6VNpiAA</delete_hash>
        <original_image>http://imgur.com/cxmHM.png</original_image>
        <large_thumbnail>http://imgur.com/cxmHMl.png</large_thumbnail>
        <small_thumbnail>http://imgur.com/cxmHMl.png</small_thumbnail>
        <imgur_page>http://imgur.com/cxmHM</imgur_page>
        <delete_page>http://imgur.com/delete/NNy6VNpiAA</delete_page>
</rsp>

How can I extract the value of each tag?

XDocument response = new XDocument(w.UploadValues("http://imgur.com/api/upload.xml", values));
string originalImage = 'do the extraction here';
string imgurPage = 'the same';
UploadedImage image = new UploadedImage();

Answer 1

Fortunately it’s pretty simple:

string originalImage = (string) response.Root.Element("original_image");
string imgurPage = (string) response.Root.Element("imgur_page");
// etc

That’s assuming your XDocument constructor call is correct… without knowing what w.UploadValues does, that’s hard to say.

LINQ to XML makes querying very easy – let us know if you have anything more complicated.

Note that I’ve used a cast to string instead of taking the Value property or anything like that. That means if the <original_image> element is missing, originalImage will be null rather than an exception being thrown. You may prefer the exception, depending on your exact situation.
