Question

PHP Regular Expression to quotations to attributes

Answer 1

+3 A:

How about using Tidy? Regexp really isn't the way to go around HTML.

I really only need to enclose the SRC='' attribute. So regex will be good for this I believe. It doesn't have to work perfectly on a large scale, just work perfectly for <img src=> situations

Well (at your own peril): `preg_replace("/=([^'" ]+)/", "=\"$1\"", $html)`. It's pretty simple but should do the job in simple and standard cases.

Thanks for your help, in my test case that yields :<IMG SRC="06032102.jpg WIDTH=250 HEIGHT=200 BORDER=0 ALIGN=left>"Can you help me refine the code?

A forgot to escape and the end angled bracket: `preg_replace("/=([^'\"> ]+)/", "=\"$1\"", $html)`. This works on my php.

Answer 2

+2 A:

Trying to parse, or validate, HTML is a complex job best not attempted with a regex. There are just too many possibilities for it to be efficient.

Jakub got there before me, but I agree. Use tools that exist for the job like HTML Tidy - http://tidy.sourceforge.net/

It can fix invalid HTML, see a nice overview at http://www.w3.org/People/Raggett/tidy/

There is some PHP integration at http://uk3.php.net/tidy
