regexp q

[[deleted]]

i just started with some regexp work and i got a problem right away. what i whant to do is validate html tags.

This works:

$data = "<span class=\"test\">";   

if(ereg("^</?[A-Za-z]{1,5} ?(([A-Za-z]){1,12}=\"([A-Za-z0-9]){1,}\"){0,1})?>",$data))     

 echo "valid";  

else  

 echo "INVALID";

but if i set $data to $data = "<span class=\"test\" title=\"testing\">"; it does not work. (invalid is printed). So i changed the regexp to following:

"^</?[A-Za-z]{1,5}( ?(([A-Za-z]){1,12}=\"([A-Za-z0-9]){1,}\"){0,1})?)*>"

But that does not wok. anybody ideas ?

thanks in advance
