Retrieve Tag Elements

[beaver6813]

Hey Guys,

Yet another question from me... sorry :santa:

Okay so say you had a meta tag for example:

<meta name="keywords" content="fun humor">
<meta name="description" content="this is a super site">

I have a snippet of code to retrieve an attribute from a specified tag:

function getAttribs($t, $a, $s)
	{
        preg_match_all("/(<".$t." .*?".$a.".*?=.*?\")(.*?)(\".*?>)/", $s, $m);
	return $m[2];
    	}

$t is the tag, $a is the attribute, $s is the content/code, $m is the new variable

But how would I find the content attribute for only the keywords tag? Since they both have the same tag name?

Something like that ?

<?php
$content = '<meta name="keywords" content="fun humor">
<meta name="description" content="this is a super site">';
preg_match('/<meta +name=["\']?keywords["\']? content=["\'](.+)["\'] *>/i',$content,$matches);
echo $matches[1];
?>

=> fun humor

There is actually an in-built function in PHP for retrieving HTML meta tags:

True but it's limited so I prefer to go with my regular expressions for parsing.

Infact, the get_meta_tags() function is far more efficient, and provides much more functionality.
