HTML markup- make uppercase

Anon

Hey,

I'd like to replace all markup in a web page with the uppercase (or lowercase) of the same...

I assumed using a regex / eregi_replace during the collection phase would do it, however, strtoupper() does not want to work inside eregi_replace...

example:

$file = "thewebpage";
$fp = fopen($file,"r");
while (!feof($fp) ) {
$line = fgets($fp, 1024);
$data .= eregi_replace("<([^>]*)>", STRTOUPPER("\1") ,$line);
}
fclose($fp);
print $data;

The replace leaves the chevrons off so I can see the result.

replacing STRTOUPPER("\1") with "XXX" will replace the tag with XXX

replacing STRTOUPPER("\1") with MD5("\1") will replace the tag with MD5 of the tag

Any suggestions why Strtoupper does not want to work yet other functions will?

just a thought... aren't functions case sensative? If so STRTOUPPER() is not the same as strtoupper().

Actually most items in PHP are not case sensitive, only a few things such as Class names are...

Anyway, further investigation using this code shows that replacing "XXX" with the MD5() function does create the MD5 of the tag, however, strtoupper() / strtolower() / ucwords() do not appear to touch the substitution... strrev actually reverses the substitution "\1 to become "1\" in the data variable...

$file = "http://www.yahoo.com";
$fp = fopen($file,"r");
while (!feof($fp) ) {
$line = fgets($fp, 1024);
$data .= ereg_replace("<([^>]*)>", XXX("\1") ,$line);
}
fclose($fp);
print $data;

Interestingly if you use a direct reference... eg.
$data .= ereg_replace("http", "FFFF" ,$line);

this works perfectly..

Still puzzled..

Dear Steve,

I think you should be using preg_replace instead of ereg_replace. I constructed to following function to convert HTML correctly to uppercase:

function htmltoupper( $string ) {

	return( preg_replace( "/\&(.)(UML|ACUTE|CIRC|GRAVE|RING|TILDE|CEDIL);/e" , "'&\\1'.strtolower('\\2').';'" , strtoupper( $string ) ) );
}

Good luck,
Jasper
