Retrieving data from a document

**sleep4ever** · May 13, 2005 19:31

My goal is to retrieve info from a document. An example would be XML or HTML. I have come up with a few ideas; however, they all seem somewhat uneffecient.

Example:

Code:

<html>
<head>
<title>Document name</title>
</head>
<body>
some contents
</body>
</html>

Then the script gets what's between the <title> and <body> tags. I thought I could use something like below, but I decided against it (if i can get better).

PHP Code:


$string = "html";

$title_pre = explode("<title>", $string);

$title = explode('</title>', $title_pre['1']);

$title = $title['0'];

Just use preg_match

PHP Code:


 preg_match('#<title>(.*?)</title>#', $string, $match);
 
 $title = $match[1];

Ahhhh. I will use that one, thank you Jump!

I'm probably going to use preg_match, but if anyone knows of a better method, feel free to tell me! =)

Thanks

For the body contents you might want to use this.

PHP Code:


$start_code = strpos($string, '<body>') + 6;
 $end_code =  strpos($string, '</body>');
 $code_length = $end_code - $start_code;
 
 $body = substr($string, $start_code, $code_length);
