Convert XML/HTML from RSS feed into something usefull?
I'm building an Windows Universal App for a Raspberry Pi 2. I used the System.Data-library (DataSet) for interpretation of this kind of info:
<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0" xmlns:content="http://purl.org/rss/1.0/modules/content/">

But now that I'm targeting Universal App, I get lots of compile errors, because the assemblies I added myself (System.Data, and a few others) won't compile to Universal App, because they are not supported. Do any of you guys know a quick and handy way to somehow convert this XML/HTML kinda info into strings? NOTICE: In the "description" attribute is BOTH located the URL for the image, AND the main text, which I would like to get separated

I found that i can use System.Xml. I'm trying to figure out how to extract "title" and "description" from each item (Look at the X$$anonymous$$L code snippet above). I'm trying this:
public void ReadX$$anonymous$$L(WWW www)
{
xmlDoc = new XmlDocument();
xmlDoc.LoadXml(www.text);
foreach (XmlElement node in xmlDoc.SelectNodes("Item"))
{
Debug.Log("I was called !!!!!!!!");
RSSItem rssItem = new RSSItem();
rssItem.title = node.SelectSingleNode("title").InnerText;
rssItem.description= node.SelectSingleNode("description").InnerText;
}
}
But i don't even enter the foreach-loop. Any of you guys know how to extract "title" and "description" ?
Found the sleekest answer for Rss feeds (see the link below). The unity package is provided for free too.

I made several attempts at the deserialization efforts and it would only partially come through. I have a feel it had something to do with the RSS element as a XLMroot or something like that. Anyway, the package above is still relevant and easily modifiable. Also, make sure you're URL to your xml file doesn't have a "https" but make sure it's "http". For some reason it didn't place nicely with the security protocol version.

Their is a lot of XML serialize out their.
This one for example: http://www.codeproject.com/Articles/34045/Yet-Another-XML-Serialization-Library-for-the-NET
Which one is best for your work is probably only you that knows.
Search for C# XML library and you will get tons of results.
