Darn regex :(

Hi,

I don't suppose anyone has any ideas why this regex isn't working?

Sample HTML:

raYIbZlPS
Visit coursework ge in ge fo ge for ge more paper ge Do ge not ge redistribute
raYIbZlPS

Code:

Code:
   $desc =~ s|\Q<span\E[\n\s+]\Qlang=EN-GB\E[\n\s+]\Qstyle='font-size:\E[\n\s+]\Q7.5pt;font-family:Verdana;\E[\n\s+]\Qcolor:#CCFFFF'>\E([\W\w\d\s\n]+?)\Q</span>\E||ig;

Its really annoying me. Basically, the format can look anything like;

Quote:

cocf cfr
secfcfw orcf cfk incf focf cf!

cocd cdr
secdcdw 

VgODf6j4 from VgODf6j4 coursewrok VgODf6j4 work VgODf6j4
info VgODf6j4 

11u2737Yu Visit
coursework gd in gd fo gd for gd more paper gd Do gd not gd redistribute
11u2737Yu

cogb gbr
segbgbw orgb gbk ingb fogb gb;

Note how the newlines are different on each of them. I have a feeling this is whats causing the problem :(

The idea behind this code, is to remove all tags that look like;

Code:
<span 
lang=EN-GB style='font-size:7.5pt;font-family:Verdana;color:#CCFFFF'>CONTENT</span>

..and;

Code:
<span 
lang=EN-GB style='font-size:7.5pt;font-family:Verdana;color:#FFCCFF'>CONTENT</span>

Anyone got any suggestions? Smile

TIA

Re: [Wil] Darn regex :( In reply to

Hi,

Thanks for the reply :)

This content is just junk, and it needs removing totally. I tried it with;

Code:
$desc =~ s|<span([\W\w\d\s\n]+?)>(.*?)</span>||sig;

.. but that also filters out the valid ones :/

The main problems seems to be the newlines. The regex could easily be;

Code:
\Q<span lang=EN-GB style='font-size:7.5pt;font-family:Verdana;color:#CCFFFF'>\E(.*?)\Q</span>\E

.. but considering some of the lines apprear as (for example);

Code:
<span 
lang=EN-GB style='font-size:7.5pt;font-family:Verdana;color:#CCFFFF'>

...or;

Code:
<span lang= 
EN-GB style='font-size:7.5pt;font-family:Verdana;color:#CCFFFF'>

.. and loads of other weird combinations :(

TIA for any sugestions :)

Cheers

Yes, but what do you want the end result to look like after its been through your regex? What do you want to get rid of, and what do you want to keep?

Re: [Wil] Darn regex :( In reply to

Hi,

I literally just want to get rid of these span tags (...), as they just hold junk text.. i.e;

sdf sfsdfs djos dgjopsd gopsjdg sg

Hope that explains what I'm trying to do better Smile

Maybe using a HTML parser module, would be a better idea, if you want a safe job done...
Just my 2 cents.

Code:
$html =~ s|</?span[^>]*>||sig;

Will that do what you want?

Re: [Andy] Darn regex :( In reply to

im not pro like this guys but here a simple way:
($content) = ( $lines =~ />(.*?)</ );
or
($content) = ( $lines =~ />(.*?)<\/td>/ );

also u can do something like
($content) = ( $lines =~ />(.*?)<\/span>/ );
