How to get some TEXT from HTML page

fux23

The problem is that I know how the HTML file looks like... and where it is... for example
www.somedomain.com/prices.html
on that page ONCE DAILY people change some numbers (for example: currency prices)...
is there a way to scan entire HTML page for some string
<B>USD: XXX</B> where XXX is the price I'm looking for...

So as a result I get today's price of EUR or USD???

THX a lot for help

theres always a first time...

http://www.php.net/manual/en/function.fopen.php

//this could not work... it depends how yr hoster is configured...
$fd = fopen ("www.somedomain.com/prices.html", "r");
while (!feof ($fd)) {
    $buffer = fgets($fd, 4096);
    echo $buffer;
}
fclose ($fd);

http://www.php.net/manual/en/function.fsockopen.php

$fp = fsockopen ("www.somedomain.com", 80, $errno, $errstr, 30);
if (!$fp) {
    echo "$errstr ($errno)<br>\n";
} else {
    fputs ($fp, "GET /prices.html HTTP/1.0\r\n");
    while (!feof($fp)) {
        echo fgets ($fp,128);
    }
    fclose ($fp);
}

handle yr text with
