Simple regex that does not work.

[alexdemers]

Hi,

 

I just want to extract ALL the content from a specific tag with a specific ID. Here's the sample of the HTML:

 

There are alot of id+integer on the page.

<div id="id1">all the tags and text in here</div>
<div id="id2">all the tags and text in here</div>
<div id="id3">all the tags and text in here</div>

 

Here's my preg_match_all function:

preg_match_all ('<div id=\"id(?:[\d]+)\">(.*)<\/div>/ism', $str, $r);
echo '<pre>';
print_r ($r);

 

The first sub pattern is to catch all the id with an integer (ie: id1, id2, id3 ... ) ... no trouble there

Then I want to get ALL the text and HTML between the "div" tags. For some reason, it doesn't stop and match at the first </div>. It continues to get all the content before reaching THE LAST "</div>".

 

This has been an issue for the past 2 hours. I can't get it to work. Maybe anyone can help me? Thanks.

I'll specify that I need the content of everything inside every different div tag with the id name like I specified.

 

Example:

 

Array
(
    [0] => "content of <div id="id1"></div>"
    [1] => "content of <div id="id2"></div>"
    [2] => "content of <div id="id3"></div>"
    [3] => "content of <div id="id4"></div>"
)

 

Thanks again

preg_match_all ('<div id=\"id(?:[\d]+)\">(.*)<\/div>/ism', $str, $r);

 

to

 

preg_match_all ('<div id=\"id(?:[\d]+)\">(.*?)<\/div>/ism', $str, $r);

 

Look into greediness of regular expressions.

Wow, I can't thank you enough

No problem.

There's no need for non-capturing parentheses or a character classed \d:

%<div id="id\d+">(.*?)</div>%ism
