string reading

[TravisB]

I made a form that you submit a url to this script. This script opens the url and reads the file looking for particular text. The text I am looking for is like: <mytag name="blah" description="blah blah" /> . I have it to the point where I know the start and end positions of the tag, but how do I make the tag into a string that I can parse looking for the name and description?

<?php
$gw_open = "<mytag";
$gw_close = "/>";

//print  submitted url out
print($url);

//open file
$handle = fopen ($url, "r");

//read file into string
while (!feof ($handle)) {

   $buffer = fgets($handle, 4096);   

   $text = $text . $buffer;

}

//search for my tag
if (eregi($gw_open, $text)) {
    echo "<br>page contains my tag!";
    $pos1 = strpos($text, $gw_open);
			echo "<br>pos = " . $pos1;
			$pos2 = strpos($text, $gw_close, $pos1);
			echo "<br>pos = " . $pos2;

//what do I do now???
}

fclose ($handle);
?>

Anyone?

if your tag has EXACTLY the format <mytag name="blah" description="blah blah" />
then it's easy:

$sub = substr($test, $pos1, ($pos2 - $pos1));
$parts = explode("\"",$sub);
$name = $parts[1];
$desc = $parts[3];

but this requires that there are only the specified " in the string

Thanks, that is exactly what I was looking for.
