Can I read from an HTML page?

ovisopa

Hy all !

My question is if a script can read from a HTML page few lines like this:

Let's say that the page www.mypage.com/test.html is something like this:

<HTML>
<TITLE></TITLE>
...
<BODY>
...

those lines I
wan't to read

</BODY>
</HTML>

If I have the "magic script" 🙂 on this page www.test.com/magic.php can I search on test.html for
 and read the next lines until I find
.

I want to display the lines betwen Coments on page test2.html

Can somebody help me with this? or it is posible to read from a html source outside my site?

10x and see ya!

sure you can - use the file() command to read the html file into an array, and go from there.

Here is a simple functional example to parse out the title of a page:

<?php
$page="http://www.yahoo.com";
$fcontents = file($page);
foreach($fcontents as $line){
	if (eregi ("<title>(.*)</title>", $line, $out)) {
		echo "<p>".$out[1];
		break;
	}
}
?>

10x and See Ya.

<?php
$page="http://127.0.0.1/sibiul/test.html";
$fcontents = file($page);
foreach($fcontents as $line){
if (eregi ("(.*)", $line, $out)) {
echo "<p>".$out[1];
break;
}
}
?>

when you use the break function, it exits the script and nothing else will execute. So what this script is doing is saying "read through the file and as soon as you find something between  and  then STOP.

if you take the break out, the script will search the whole script and not stop after the first result.

let me know if you need anything else...

The way you worded the question, Weekenders suggestion would fix it and allow you to print multiple matches.

If, on the other hand, you are having a problem with the matching start and end tags being on separate lines then you will need to get rid of the line breaks by converting the entire file into a string, then parse that single string with a foreach loop to pull out the matching data.
