Newbie Help needed - preg_match regex line break issues!

[youngnickodemus]

Hi all,

 

I'm really having issue with something that i think should be very basic, but it's really starting to get on my nerves...if anyone can help i'd really appreciate it!

 

Basically i've written a price scraping script which works fine for most things, but i'm struggling to write the regex for one particular price i'm trying to scrape from a site.

 

The html i'm searching through is:

 

<span class="lprice">

      £312.34

</span>

 

I want to extract the price '312.34', but i can't get any joy at all.

 

The php i'm using is basically:

 

$expression = "<span class=\"lprice\">\n£(.*?)\n<\/span>";

preg_match($webpage, $expression, $result);

 

I'd really appreciate any advice!

 

THanks,

 

Nick

You missed the space/tabs between the span open tag newline and the £

Thanks Mike.

 

I just tried:

 

<span class=\"lprice\">\n(.*?)£(.*?)\n<\/span>

 

and that didn't work either....? any ideas??

 

Cheers,

Tried that here, and seems OK:

I'm no regex expert though - use it v rarely so can't help much more...

<?php
$string = '<span class="lprice">
       £312.34
</span>';

preg_match("~<span.+?;(.+?)</span>~is", $string, $matches);

$price = $matches[1];

echo $price;

die();
?>

 

Should do what you want.

 

As a note if you have multiple spans with a ; inside of them you may want to add the class= part. If you do not then this should be fine, especially if it is the first span, as this will only match the first item on the page that matches that regex.
