Remove style attribute from HTML tags

Question

I m not too good with regular expressions  but with PHP I m wanting to remove the style attribute from HTML tags in a string that s coming back from TinyMCE   So change  lt p style       gt Text lt  p gt  to just vanilla  lt p gt Test lt  p gt    How would I achieve this with something like the preg replace   function

Here you go    lt  php   html     lt p style  border  1px solid red   gt Test lt  p gt    echo preg replace    lt p style         gt       lt   p gt  i     lt p gt  2 lt  p gt     html      gt    By the way  as pointed out by others  regex are not suggested for this

You could handle it client side  the easiest would be with jQuery  Something like       tinyMce p   removeAttr  style

The pragmatic regex   lt    gt     style  quot     quot  will solve this problem in all reasonable cases  The part of the match that is not the first captured group should be removed  like this   output   preg replace     lt    gt     style  quot     quot  i     1    input    Match a  lt  followed by one or more  quot not  gt  quot  until we come to space and the style  quot     quot  part  The  i makes it work even with STYLE  quot     quot   Replace this match with  1  which is the captured group  It will leave the tag as is  if the tag doesn t include style  quot     quot
