nope, not quite... Here's what I've got-
$pattern='/\bsrc=([\'|"])([^\1])*[\1]/im';
the string that's coming in is-
<IMG SRC="http://www.mydomain.net/templates/images/somepicture.gif"; ALT="letter" BORDER="0" ALIGN="CENTER">
That's no newline or anything like that within the code (even with the 'm' option, i've had previous problems with that before), and I can simplify the expression and grab everything including the quotes, so I'm really not sure what's failing.
Thanks- Thaddeus

Lets say I'm trying to extract some data from an HTML document. I want to get the values of the 'src' attributes of various tags.
For example- <img src="http://www.yahoo.com";>
here's the pattern I've been trying-
/\bsrc=(['|"])[^\\1]*[\\1]/im
Basically, match the 'src=' followed by some type of quote, followed by stuff that's not the quote originally matched, followed by the same quote.
But, obviously, I can't run this, because the quotes in the pattern close off the string I'm trying to create.
Are there ways of working with quotes?
Just escape the quote like you've escaped the backslashes.
If double-quoting:
$pattern = "/\bsrc=(['|\"])[^\\1]*[\\1]/im";
If single-quoting (better, if you don't variable interpolation) you don't even need to escape the backslashes, so:
$pattern = '/\bsrc=([\'|"])[^\1]*[\1]/im';
Cheers!
