I've read how accented characters might sometimes match [a-z] . What I'd like to know is how I could match a specific accented character. Obviously, preg_match('/[ñ]/', 'ñ') does not work.

Hello,
I have some data similar to this:
aaa1|aaa2|ZZZ|aaa3|aaa4|aaa5|ZZZ|aaa6|aaa7
I want to match all "aaa[0-9]" BETWEEN "ZZZ" (not the ones outside).
So I have some PHP code: $string = "aaa1aaa2zzzzaaa3aaa4aaa5zzzzaaa6aaa7"; preg_match_all("/zzzz.*...

I'm confused about the array returned by a regex match when using both /g (to get multiple matches) and parentheses (to get backreferences). It's not clear to me how to get the backreferences because the subscript of the match array seems to refer to ...

You should use non.
Var str = "@abc @bcd @cde", re = /@([a-z]+)/g, match; while (match = re.exec(str)) { // match[1] contains text matched by first group, match[2] - second, etc.

For example, the string might be:

If you want to check if something matches a regex, if so, print the first group, you do..
import re match = re.match("(\d+)g", "123g") if match is not None: print match.group(1)
This is completely pedantic, but the intermediate match variable is a bit...

I'd suggest not using a regex to parse.
There's nothing to match title="Wat" in the <a> tag.

Consider the following Javascript regular expression matching operation:

Use Test::More 0.88; #Match any whole text" if $text !~ /ac/;
or
print "ac not found" unless $text =~ /ac/;

You can easily modify this regex for your purpose.
