Comment on Extracting images from HTML using regular expressions by zytzagoo

@Richard:

1. Using ‘#’ instead of a forward slash is an old habit I picked up. You can use almost any character, as long as they’re unique and identical. With forward slashes being a rather common occurence inside a src attribute, I chose to avoid them as a delimiter. It’s true that a ‘#’ might also appear inside a src — but I didn’t test if the regex compilation in php would fail in such cases. It could.

2. Because I wanted to capture zero or more of that preceding block. Learning by example might be easier: go to http://erik.eae.net/playground/regexp/regexp.html , paste in the 4 example img tags from the post, and paste in the regex from the post. Now you can change the regex there interactively and see what works and what doesn’t.

3. It doesn’t necessarily. The question mark makes it non-greedy, and since I wasn’t interested in the remaining attributes, I figured it would make it faster. It could very well make it slower — I didn’t test for that :)

4. That’s a backrefrence. Backreferences allow you to reuse a part of the regex match. It can get complicated, but it’s also quite powerful. Google for more.

Hi,
I’ve just started learning regex’s and understand most of '#]*src\s*=\s*(["\'])(.*?)\1#im’; but can someone shed some light on a few issues?


1. Why does it use '#' instead of '/' as delimiters?
2. Why does the not angle bracket part( [^/>] ) need an ‘*’ afterwards?
3. Why does the (.*?) need the ‘?’
4. Oh and what does ‘\1′ at the end mean?

Ok that was more questions than I thought but would be grateful if someone could clarify?

Indeed. Using up all the rules from usability studies all over the web, for all the wrong reasons :)

What he said. Brilliant!

Now, if you forget about how wrong this is for a second - I presume that the guy who figured this out must be tremendeously proud of himself. Hell, he probably got a big thumbs up from his boss aswell. What a mindset!

This is brilliant indeed.

I pressed OK just out of curiosity, and my ESET Security started blocking things and alerting me that something f*cked up is going on. :)

Hm, no one can recommend VLC player? beside of itunes that I love, VLC is the next player I could recommend, expecially for his streaming options. But, your choice is your choice right? :P

I used Foobar and iTunes but something keeps me going back to the good ‘ol Ljama Ass Winamp, maybe its because that I’m a keyboard control winamp addict… I dunno
