找出正确的preg_match正则表达式匹配

Question

I am curling a page with php and then I am looking to find a section within that page. That section opens and closes with the html5 <section> tag like this:

<section id="postingbody">
   blah blah blah content
</section>

I am not sure how to get my matching working properly. Just to fill in the matching portion here:

preg_match("/ id=\"postingbody\"\">???????<\/section>/i", $compiled_results, $matches2);

Edit

So here is an example section of the content

<section id="postingbody">
    Looking to find a side job ( working your own hours ) or career in the new media field & internet marketing? Web design, graphic design, SEO, Printing & Internet marketing company looking to hire a sales team member. We have 10+ years experience in the Web design & marketing field. Work your own hours, competitive commission rates, we can also train the right candidates for sales. Our office is located in New Jersey.<br>
</section>

So the examples here don't seem to work.

Answer 1

Try this:

preg_match("/(?s)<section id=\"postingbody\">((?:.)*?)<\/section>/i", $compiled_results, $matches2);

Edit: For example, the following code works as expected for me (the value is in $matches2):

$compiled_results = '<section id="postingbody">

</section>';
preg_match("/(?s)<section id=\"postingbody\">((?:.)*?)<\/section>/i", $compiled_results, $matches2);
var_dump($matches2);
