Preg_match_all help

I need to extract all href from external css link e.g.

<link rel="stylesheet" href="main.css" type="text/css"> OR
<link rel="stylesheet" type="text/css" href="main.css"> OR
<link href="main.css" type="text/css" rel="stylesheet" > OR

from any of combination of insides attributes. Simply I just need to find all external css location,


Expected Result:
main.css


Pls help

 

It seems you need a lot of regular expressions, I think it would be very useful to learn them, instead of posting whenever you need one.

 

^ I agree...

Anyway...

preg_match_all('~<link[^>]+(?:(?:href="([^"]+)"|type="text/css")\s*){2}[^>]*>~', $html, $matches);

echo '<pre>', print_r($matches[1], true), '</pre>';

PHP:

 

I am agreed too. thanks for help.

I think ,I will help others next time when they need reg exp problem.

Thanks

 

Hi,

Does not work. Since all pattern seems to same to me, I cant find the error.

What the the problems?

 

"(?:" - care to explain please nico?

 

I've tried it, and it works just fine for me:

$html = '<link rel="stylesheet" href="main3.css" type="text/css"> OR
<link rel="stylesheet" type="text/css" href="main5.css"> OR
<link href="main4.css" type="text/css" rel="stylesheet" > OR';


preg_match_all('~<link[^>]+(?:(?:href="([^"]+)"|type="text/css")\s*){2}[^>]*>~', $html, $matches);

echo '<pre>', print_r($matches[1], true), '</pre>';

PHP:

Gives me:

Array
(
    [0] => main3.css
    [1] => main5.css
    [2] => main4.css
)

Code (markup):

How did you try it?

That means this group won't be captured in the matches array.

 

Hi nico,

Thanks for the help. Your expression does not give result. Could you please look at?

 

I did... but I can't help unless you answer my question...

 

Hi Nicho,
My html was as

$html='<meta name="Author" content="Bdjokes.com" />
<meta name="Rating" content="General" />
<title>bdjokes :: A collection of jokes in bangla(Bangla Jokes)</title>
<link href="css.css" rel="stylesheet" type="text/css">
<link href="style.css" rel="stylesheet" type="text/css">
</head>';
preg_match_all('~<link[^>]+(?:(?:href="([^"]+)"|type="text/css")\s*){2}[^>]*>~', $html, $matches);

echo '<pre>', print_r($matches[1], true), '</pre>';

PHP:

but no result...



Thanks

 

Works for me:

'~<link[^>]+(?:\s*(?:href="([^"]+)"|type="text/css"|rel="stylesheet")\s*){3}[^>]*>~'

PHP:
