getting portion of a document

[abdfahim]

Dear expats,

 

I want to get only the portion between <marquee></marquee> tag of an html document. Can you please validate the expression below.

 

Say, I have whole html document in the variable $a. So, why $h1 is not returning properly?

$h1 = preg_replace("/(.*?)<marquee[^>]*>(.*?)<\/marquee>(.*?)/i", "$2", $a);

 

Sorry for being very weak in regex

Is there any reason why you want to use regex over, say, a real HTML parser?

 

A basic example would look a bit like:

 

$doc = new DOMDocument;
$doc->loadHTML($a);

$h1 = $doc->getElementsByTagName('marquee')->item(0);
echo $doc->saveXML($h1);

that's great. I never used HTML parser. Just one thing, can you tell me how can I save the output rather then sending to browser?
