HTML: regex expression to match multiple examples

Question

I have an HTML text, where I want to find images and videos. Found some examples, but can't make it work.

I have working example for only images:

MatchCollection urls = Regex.Matches(this.item.text, "<img.+?src=[\\\"'](.+?)[\\\"'].*?> );

For both i want to make something like this:

MatchCollection urls = Regex.Matches(this.item.text, "<img.+?src=[\\\"'](.+?)[\\\"'].*?> | <iframe .*?/> | <iframe .*?</iframe>");

The last regex found 0 images, where first got 3.

Use an HtmlAgilityPack to parse HTML in C#. Regex is not the best tool for this. — Wiktor Stribiżew, Aug 02 '17 at 07:22
I'll repeat the standard response that should be given *every time a question like this is posted*: **Do not use Regex to match HTML**. Use an HTML parser. — Tom Lord, Aug 02 '17 at 08:20

Try the following:

(<img.+?src=[\\\"'](.+?)[\\\"'].*?>)|((<iframe.*?\/>)|(<iframe.*?<\/iframe>))

You were missing the parenthesis.

MatchCollection urls = Regex.Matches(this.item.text, "() | (() | ())"); not working – Vadim Aug 02 '17 at 07:33
