Only return the first instance of "X"

[soma56]

Ok, so I've figured out how to parse and bring back content from within <title> and </title> tags.

 

However I'm having a heck of a time trying to figure out how to grab the contents between

 

<meta name="keywords" content="grab-this-content" />

 

My program seems to grab everything that ends with "/>". The keywords, in addition to several other elements that I don't need. The only thing I want is between:

 

<meta name="keywords" content="

 

and the first instance of

 

/>

 

Does anyone understand what I'm trying to do? Can you please give me some direction?

preg_match will do what you want. http://au.php.net/manual/en/function.preg-match.php

~<meta name="keywords" content="([^"]+)~

 

$str = '<meta name="keywords" content="grab-this-content" />';
preg_match('~<meta name="keywords" content="([^"]+)~', $str, $matches);
print_r($matches);

Actually - in this case you may find using the DOM and XPath a better method - preg_match is expensive and slow...

 

something like:

$doc = new DOMDocument();
$doc->loadHTMLFile("/path/to/your/file.html");
$xpath = new DOMXpath($doc);

 

then you can grab all manner of info without having to run preg_match over and over again..

 

$title = $xpath->query("//title")->item( 0 )->nodeValue;
$keywords = $xpath->query("//meta[@name='keywords']")->item(0)->getAttribute('content');

 

and so on and so forth...

 

You should find this method a bit more efficient/quicker and a bit more fun
