Getting an image source with sed

Question

If I have a line of text which looks like...

[garbage] <img src="[some url]" [garbage] /> [garbage]

Using sed, how can I get the URL that the image is pointing to? There are no other instances of src= on that line.

cat html | sed -n 's/.*<img src="\([^"]*\)".*/\1/p'

The -n /p idiom allows you to ignore all the other lines in the file (i.e. do a sed and a grep in one go), while "([^"]*)" just says find the stuff in the quotes.
