Regex - Extracting img src from HTML

Question

I know I should not use regex in HTML. I would like to extract image sources from an HTML file, example below:

It might look like this:

<img src = cid:header width="700" height="93" alt="Logo" />
<img src= cid:header width="700" height="93" alt="Logo" />
<img src =cid:header width="700" height="93" alt="Logo" />
<img src=cid:header width="700" height="93" alt="Logo" />

In each case, I'ld like to get "cid:header" as the result.

Since my regex knowledge is basically zero, I turn to you guys. I need a pattern that accepts a space after "src" or after the "=" character.

src[mightBeSpace]=[mightBeSpace]cid:[mustNotBeSpace]

Thank you!

I've provided this as-is to match one line of txt that contains only what you've provided. Be aware (as pointed out by @Kolink) that RegEx is horrible at matching HTML – rbedger Mar 18 '13 at 18:11
src\s?=\s?([^\s]+) this is the only party I needed, thank you! – Dominik Antal Mar 18 '13 at 18:18

"might be space" in regex is \s*, and "must be no space" translates to \S+

Using this information you should be able to build a regex. If you can't, please show what you've tried.
