[Regular expression help: need to strip bookmark tags <a name...]

One of your <a> tags has content and there are no hrefs? How about !<a[^>]+name="[^"]+"[^>]*>.*?</a>!is?

With a flexible approach to a "number" or "word":

 

<pre>

[[SOLVED] regex - preg_match'in html]

| is a metacharacter in regex. Use \| to match a literal pipe. explode would be better in this instance.

[[SOLVED] regex - preg_match'in html]

The function automatically arrays the captures; observe print_r($match);.

[[SOLVED] regex - preg_match'in html]

You're matching HTML, so you're not going to see it if you print it--the browser is parsing it.

 

<pre>
<?php
$str = '</td> </tr> </table>';
preg_match('%</td>\s*</tr>\s*</table>%', $str, $matches);
foreach ($matches as &$match) {
	$match = htmlspecialchars($match);
}
print_r($matches);
?>

[[SOLVED] More problems with that URL regex.]

At some point the . was \S to only capture non-whitespace. I can't figure out why this changed in the old posts, but that's what you're after. I've restored this and cleaned up the img addition with alternation:

 

preg_match_all('%
      (
         (?>
            ### Protocol or start.
            (?:
               (??:https?|ftp)://)
               |
               www\.
            )
            ### Body: gobble non-space, [/url], [/img]
            (??!\[/(?:url|img)\])\S)+
            ### Avoid ending punctuation.
            (?<!\s\p{P})
         )
         ### Not followed by an url/img end.
         (?!\[/(?:url|img)\])
      )
      %x', $str, $matches);

Can you include a full sample of data since "Chat" and "Username" gave you trouble? Are you simply trying to remove the brackets, or add the text shown in your example as well?

[Parse out all image tags and attributes in Perl]

2. Do you mean like:

$1 =~ /(\w+)\s*=\s*"([^"]+)"/g

(notice the addition of \s*)

 

Yes.

[Parse out all image tags and attributes in Perl]

1. You're only going to catch double-quoted attributes.

2. You haven't accounted for rogue white space.

3. There are various modules on CPAN for things like this; my take is below:

 

use strict;
use warnings;
use XML::Twig;
use Data::Dumper;

my $data = <<HTML;
<img src="foo" height="1" />
<img src="testing!" height="50" width="200" />
<img height="20" src="lol" />
HTML

my @atts;
my $twig = XML::Twig->new(
twig_roots => {
	'img' => sub {
		push @atts, $_->atts();
	}
}
);
$twig->parse_html($data);
print Data::Dumper->Dump([\@atts]);

[Quantifier limit]

You could try a split between the two desired patterns--/(?:A|B)/--and move forward from there. If you need additional help, please provide more data.

[Quantifier limit]

I believe this is what the manual is referring to here:

 

All values in repeating quantifiers must be less than 65536.

 

There must be a better way of partitioning or analyzing your data.
