[PHP] HELP: Regex pattern matching
I have an ASCII file which has multiple blocks of text I want to clear. The scheme is as follows: =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- line 1 Everything between the separators, line 2 including the separators line 3 I want to clear from the text file line 4 - This text I want to keep There are infinite number of blocks surrounded by exactly the same separators. So, I guess I need to clear everything between the starting = and the ending -. Can anyone suggest a regex pattern string that would help me accomplish that? Thank you all guys in advance!

Re: [PHP] HELP: Regex pattern matching
Hmmm... I was about to reply with a simple solution, but there's a problem with it
that I can't explain. Assuming the text is in $str...
I can't get preg_replace to match a newline at the end of a pattern. If I use...
$str = preg_replace('/\n=.+--\n/sU', '', $str);
...it matches nothing, but if I put a tag character at the end of the dashes, e.g.
x
...then use...
$str = preg_replace('/\n=.+--x/sU', '', $str);
...it works perfectly. I'm not sure why the pattern doesn't care about the first
newline, but it chokes on the second one. Any thoughts?
Thanks,
Alex

Hmm... i'm not that advanced...
May be first I replace any string containing --- with ---x, then use
your solution?

Re: [PHP] HELP: Regex pattern matching
If the separators are always the same length, then you can use the
following:
$new_str = preg_replace(/(=-){5}(.*)-{10}/sU,,$str);
Where 5 is how many times the =- pattern repeats, and 10 is how many times
the - character repeats.
Hope that helps.

[PHP] Help with pattern matching.
Hi, I'm looking for somebody to give me a hand to create some expressions to extract my information out of an ebay auction page. So that I can manage them more effectively. I've try lost of patterns but can't seem to get the hang of it. Is there anybody willing to lone their brain to a php newbie before my computer gets both barrels? Thanks Will
