preg_match question

[Hiccup]

I am reading a webpage into a file. Then I want to display the contents that are between: "<form" and "</form>" while still including "<form" and "</form>".

I have tried this:

$url="http://www.webpage.com/submit.html"; 
$file = file($url); 
if ($file) { 
	$lines_array = $file; 
	$lines_string = implode('', $lines_array); 	
} 
else{
	echo "<p>Unable to open remote file.<br>\n"; 
}

preg_match("/<form(.*)<\/form>/i", $lines_string, $match);
print $match[1];

Which doesn't work. The $lines_string variable is there and working, but when i use my attempt at matching, nothing happens. I've searched for a couple hours now and am sure it's some stupid mistake I'm making...

Help?

Or is there some code already written somewhere that can take a remote form and display all the inputs?

The '/' character in the regex is probably throwing your search off.

Why not use $start = strpos( $lines_string, '<form' ) and $end = strpos( $line_string, '</form>' ) then get the form with $form = substr( $lines_string, $start, $end ).

Of course you'd have to keep looking for <form> and </form> tags until you've searched all of $line_string; and look for <FORM> and </FORM> as well.

A better soln. might be to process the page as xml, which, after all html is a subset of. 😃
