Extracting data from a page

Napster

I need to be able to extract the current value of a stock from a website. For example the stock AMM at http://asx.netquote.com.au/snap_ret.asp?c=amm

The current value of it is $0.160 under value. Well, from my website I need to extract the current value of that stock from that page but I am not sure how to do it. Any help is appreciated.

Thanks in Advance

[man]preg_match[/man] would probably be the best way to extract the data from the page unless they provide some other sort of feed like yahoo does to retrieve stock data.

I am sorry, I do not know if it is me, or that I am really tired, but I do not see how you can use that function to get the current stock value?

Um, did you read the terms of usage? I'm sure if you asked, the Exchange would have a more convenient format available.

I am not sure what you're talking about...

I do have an account there.

they are saying its against their terms to mine data from their pages.

but the preg_match function can extract any data from a page.

$target = "<td>some html code here <b>IM WANTED DATA</b> more stuff </td>";

$reg = "/<b>(.*?)<\/b>/i";

preg_match($reg, $target, $match);

echo $match[1];  //contains IM WANTED DATA

thats a simple example to say the least but it shows what its capable of. you will need to read about regular expressions at www.php.net/pcre they have a decent intro tutorial to get you started.
