preg_replace

Cadish · August 28, 2004, 05:14:57 AM

Hi, I've some string like this:

...
<body>
<p>Some text</p>
...
</body>
...

How can I replace the string into something like this:

Code Select


<p>Some text</p>
...

So just everything inside the <body></body> - tag?

Thanks

$string = str_replace('~^.+?<body[^>]+?>~', '', $string);
$string = str_replace('~</body>.+?$~', '', $string);

That should do it, no? Simplified, of course...

I would probably do it like this

$str = preg_replace('~^.*<body>(.*)<\/body>.*$~isU', '$1', $str);

Hi,

I don't understand why this shouldn't work with a page like this:

Code Select

....
&nbsp;<a href="/cgi-bin/citybild?SID=0642195b829afc479147d46cc4c1eedf098a4&PROVIDER=anwendung&WMO=06421&LANG=nl" target="daten" onClick="DownWindow('/wb/reise.htm')">Leuven</a><br>
....

I need the number after "SID=". How can I get this number easily?

Thanks!

Actually, this is from another website...

Saleh · August 31, 2004, 03:15:27 PM

then $_GET['SID']; might do, no?!

No, don't think so

I'll explain my problem: I want to fetch a website, but need to have the SID-number (which is on another, in the way I said). So, imho, the only way to do it is with regexp...

Try this:

$str = preg_replace('~^.*<a href="\/cgi-bin\/citybild\?SID=(.*)&PROVIDER.*$~isU', '$1', $str);
