Question

I’m trying to have my console application return me all of these values in a html webpage:
<img border="0" alt="img.jpg" title="img.jpg" src="/_layouts/images/icjpg.gif" />

However I’m only interested in the title="img.jpg".
I’ve seen that Regular expressions can be used to filter these, however I don’t see how I filter the rest away and only keep title="img.jpg" or the value in the title="THIS"

Any help would be appreciated.

I’ve seen this cheatlist for regex

Better solution is to use HtmlAgilityPack to parse HTML.

Example [only img tags with border = “0”]

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(your html string);

List<String> titles = (from x in doc.DocumentNode.Descendants()
                       where x.Name == "img"
                       && x.Attributes["title"] != null
                       && x.Attributes["border"] != null
                       && x.Attributes["border"].Value == "0"
                       select x.Attributes["title"].Value).ToList<String>();

This LINQ code return titles for all img tags.
