This function will work for one list per text call: function convert_to_list($text)
{
$pattern1 = "/(\#\#\n)((\#{1})[\w?\s?\W?\S?]+\n)*(\#\#\n)/";
$replace1 = "<ul>$2</ul>"; $list = preg_replace($pattern1, $replace1, $text); $pattern2 = "/(\#{1})(\w{1,}.+)?\n/";
$replace2 = "<li>\\2</li>"; $text = preg_replace($pattern2, $replace2, $list);
return $text;
} I haven't been able to get it working for multiple lists in the same piece of text... perhaps someone here is able to tweak the regex a little so it will do multiple replacements successfully? I'm still discovering regex's myself, so it's probably not that efficient. :(

Thank you! I don't understand the regex completely, but I know what it does ;) It would be great if anyone could help getting this regex work with multiple lists in a text string. Thanks!

If you want to learn some more about regex's heres a couple of links. Handy to know, especially when filtering and validating content: Sample regex's (regex library)
[regexlib.com...] In depth Regex tutorial
[regular-expressions.info...] O'reilly regex pocket reference (PDF)
[oreilly.com...] More regex references (this is probably the best one for beginners)
[phpbuilder.com...]

You made me curious if that's possible as a single regex. This seems to work:
#!/usr/bin/perl -w
$a=<<EOT;
##
#list item1
#list item2
#list item3
##
another list
##
#another 1
#another 2
##
EOT $a=~s{(^¦\r¦\n)
\#\#([\s\r\n]+)
((?:\#.*?[\r\n])+?)
\#\#([\r\n\s]+)
}
{ local $prefix=$1 . '<UL>' . $2;
local $suffix='</UL>' . $4;
(local $lines=$3)=~s/^#/<LI>/mg;
$prefix . $lines . $suffix;
}gsex; print $a;
As a bonus you get 'gsex' (great sex) as a regex qualifier :)

@andrew_m: Thanks for your help! I honestly have no idea what your regex is doing for most of the time. I tried to run it as a PERL script, but it didnt work. The error was: Can't find string terminator "EOT" anywhere before EOF at ./perltest line 2. How can I get this working inside PHP's preg_replace() function? Thanks!

I have no idea, sorry, don't know a thing about php. I thought you asked about perl and it does work fine in perl -- it's cut-n-paste from the actual script that I ran to test it.
