finding a string between two other strings...

dbmasters

I am doing some screen scrapping with PHP. When I snag the code from a URL, I want to grab the contents of the META tags, so, whatever exists between:

as well as

And then, everything between:

and </body>

Put I do not want the beginning and end delimiters included in the returned string...is there a nice easy PHP function or user defined function that can do this, it doesn't seem like something that should be that hard of a task but it's giving me problems...

little help?

Thanks.

there is built in functions to get meta tags.

here's an example from the php manual:

<?php
// Assuming the above tags are at [url]www.example.com[/url]
$tags = get_meta_tags('http://www.example.com/');

// Notice how the keys are all lowercase now, and
// how . was replaced by _ in the key.
echo $tags['author'];      // name
echo $tags['keywords'];    // php documentation
echo $tags['description'];  // a php manual
echo $tags['geo_position']; // 49.33;-86.59
?>

to find the value between 2 body tags, you could use something like this:

<?
$string = "<html>
<body> this is the body text

</body>";

$start_pos = strpos($string,"<body>"+6);
$end_pos = strpos($string,"</body>");

$body_text = substr($string,$start_pos,$end_pos);

echo $body_text;
?>
