php - regex to match div tags -

i'm using regex match specific div's in page , replace them custom formatted one. can't use domdocument pages process mal-formed , after running through domdocument, pages reformatted , don't display same.

i'm using following works perfectly:

preg_match('#(\<div id=[\'|"]'.$key.'[\'|"](.*?)\>)(.*?)\<\/div\>#s', $contents, $response); 

to match div tags such as:

<div id="test"></div> <div id="test" style="width: 300px; height: 200px;"></div> etc... 

the problem i'm encountering tags id after style or class, example:

<div class="test" id="test"></div> 

if run following, regex seems become greedy , matches ton of html before div tag, i'm not sure how fix this:

preg_match('#(\<div(.*?)id=[\'|"]'.$key.'[\'|"](.*?)\>)(.*?)\<\/div\>#s', $contents, $response); 

does have ideas?

you can use ungreedy modifer (u), , - not use .*, [^>]* (which means not > > end of tag , searching withing tag). don't need escape / when not delimiter (you using # delimiter)

preg_match('#(<div[^>]*id=[\'|"]'.$key.'[\'|"][^>]*>)(.*)</div>#isu', $contents, $response);
