Regular Expression to get the SRC of images in C#

Question

I\'m looking for a regular expression to isolate the src value of an img. (I know that this is not the best way to do this but this is what I have to do in this case)

Answer 1

I know you say you have to use regex, but if possible i would really give this open source project a chance: HtmlAgilityPack

It is really easy to use, I just discovered it and it helped me out a lot, since I was doing some heavier html parsing. It basically lets you use XPATHS to get your elements.

Their example page is a little outdated, but the API is really easy to understand, and if you are a little bit familiar with xpaths you will get head around it in now time

The code for your query would look something like this: (uncompiled code)

 List imgScrs = new List();
 HtmlDocument doc = new HtmlDocument();
 doc.LoadHtml(htmlText);//or doc.Load(htmlFileStream)
 var nodes = doc.DocumentNode.SelectNodes(@"//img[@src]"); s
 foreach (var img in nodes)
 {
    HtmlAttribute att = img["src"];
    imgScrs.Add(att.Value)
 }
