Yes, you're going about it the wrong way. Read the thread; read the tut; read the docs. Simply copying code won't teach you much (about which, more, below).

The dot in your regex stands for any character, whatsoever. That's not what you want.

And, * NOT * just BTW, the quantifier {0,10} makes no sense on several grounds.

1. In valid (and useful) html, img alt="" src= will never be followed by zero characters.
2. In most of the html I see, you can't count on getting the address link immediately after the alt description.
3. Many webmonkies, me included, prefer to see the source address first (and don't usually leave the alternate description empty)
4. Since you're apparently looking for the address of the image, you limit of 10 chars is unlikely to capture the whole address.

I suspect what you've done here is "cargo culted" some code you didn't understand. I understand that that's part of one style for learning, but it's dangerous if you don't study the code and the Perl documentation well enough to be sure you * DO * understand before using it.
