Question

I am currently working with an XML document which has RSS feeds inside. And I wanted to parse it so that if a div tag with a class name “feedflare” is found, the code would remove the whole DIV.

I could not find an example of doing this as the search for it is polluted with “HTML editor errors” and other irrelevant data.

Would anyone here be kind enough to share methods in reaching my goal?

I must state that I DO NOT want to use HtmlAgilityPack if I can avoid it.

This is my process:

Load XML, parse through elements and pick out, Title, Description, Link.
Then save all this as HTML (with tags being added programatically to build a web page) and then when all of the tags are added, I want to parse the resulting “HTML text” and remove the annoying DIV tag.

Let’s assume “string HTML = textBox1.text” where textBox1 is where the resulting HTML is pasted, after parsing the main XML document.

How would I then loop through the contents of textBox1.text and remove ONLY the div tag called “feedflare” (see below).

<div class="feedflare">
<a href="http://feeds.gawker.com/~ff/kotaku/full?a=lB-zYAGjzDU:1zqeSgzxt90:yIl2AUoC8zA">

</div>

Thank you in advance.

Using this xml library, do:

XElement root = XElement.Load(file); // or .Parse(string);
XElement div = root.XPathElement("//div[@class={0}]", "feedflare");
div.Remove();
root.Save(file); // or string = root.ToString();
