cURL, preg_match and skipping spaces!

[daydreamer]

Hi.

 

Im using cURL and php to download a page and save it in a variable.

 

Somewhere in the html code of the downloaded page will be this:

 

 

<input type="hidden" name="example" value="0bb49ad4f2276624018e2011bc6a5282">

 

I need to extract the value from the html code.

 

Would I use preg_match to find the keyword "example" (it will be unique), and then somehow skip along 9 spaces, and take the remaining 32 digits and store them in a variable?

 

How else could I do this/how would i skip along 9 spaces and get the numbers/letters

0bb49ad4f2276624018e2011bc6a5282

?

<pre>
<?php
$str = '<input type="hidden" name="example" value="0bb49ad4f2276624018e2011bc6a5282">';
preg_match('/<[^>]*name="example"[^>]*value="([^"]+)/', $str, $matches);
array_shift($matches);
print_r($matches);
?>
</pre>

I've picked up a few things off of http://www.regular-expressions.info/.

 

 

Mainly it's the concept that's kind of weird for some people, and then once they get it, it's just figuring out which symbols to use.
