Here is something that I have used in the past with great success.
<?php
// Grab source code from a file or web site
if(!($myFile=fopen("http://www.yahoo.com","r")))
{
echo "Sorry! This feature is currently not available.";
exit;
}
while(!feof($myFile))
{
// Read each line and add to $myLine
$myLine.=fgets($myFile,255);
}
fclose($myFile);
// Extract everything between start and end. You need to include these lines
//in the headlines or pick some unique substring in the html to mark the start
//and end of the news.
$start="<html>";
$end="</html>";
$start_position=strpos($myLine, $start);
$end_position=strpos($myLine, $end)+strlen($end);
$length=$end_position-$start_position;
$myLine=substr($myLine, $start_position, $length);
// Display HTML
echo $myLine;
?>
Hope you can make sense of it. It is actually pretty easy.
