How to make [^.....] for sting instead for chars...

How to make my regexp to catch the following strings:

Quote:

but not to catch the following:

Quote:

to catch the first 3 strings i tried this:

Quote:

'@<a[^>]*classname[^>]*>.+</a>@i'

Unfortunately it catches the second one too. I cannot figure it how to replace .+ so (or any other tag) to pass except </a> tag.

Aren't you really just checking that there aren't two </a>s in the string?

Here is an example what i'm trying to do:

PHP Code:


		
			
//I have a string i need to parse but for this example i'll create one from the 4 strings in my first post:



$string  = '<A class="classname" href="http://domain/subfolders">some text <BR /> more text</A>';

$string .= '<A href="http://domain/subfolders" class=classname>some text <BR /> more text</A>';

$string .= '<A href="http://domain/subfolders" class="classname">some text more text</A>';

$string .= '<A class="classname" href="http://domain/subfolders">some text more text</A>more text</A>';







$array_categories=preg_match_all('@<a[^>]*classname[^>]*>.+</a>@i', $string, $matches);

print_r($matches);

i need to get output like this:

Quote:

Array
(
[0] => Array
(
[0] => <A class="classname" href="http://domain/subfolders">some text more text</A>
[1] => <A href="http://domain/subfolders" class=classname>some text more text</A>
[2] => <A href="http://domain/subfolders" class="classname">some text more text</A>
)
)

Oh, that's all?

PHP Code:


		
			
 preg_match_all('#<a[^>]*>.*?</a>#i', $string, $matches)

If you want the class=classname,

PHP Code:


		
			
 preg_match_all('#<a[^>]*?class="classname"[^>]*>.*?</a>#', $string, $matches)

Much more and it'll be easier to do this with something like DOMDocument.

The first one looks for a <a, grabs everything up to the next >, then finds everything up to the first </a> it encounters.

The second one looks for a <a, grabs some stuff, finds a class="classname", grabs everything else up to the next >, then finds everything up to the first </a> it encounters.
