Can anybody tell me a regular expression to use within some PHP to find the following:

  1. <p>&nbsp;</p> with any variation of white space between those tags

  2. <p><br/> again with any variation of white space between those tags

Any help appreciated, thanks!

    Oh god, there's so much blood http://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags/1732454#1732454.... Should probably look into a parser instead. – Robert Sep 25 '10 at 17:09

If you want to parse XML (or HTML) you should think about using a XML parser instead of regex. It would be more efficient.

PHP already contains an XML parser which is good for you :)

  • Hey, thanks. It’s actually for a parameter within an ExpressionEngine find and replace plugin, which I thought would be using PHP. – James Sep 25 '10 at 17:14
  • XML parser vs. regex isn't necessarily "more efficient" depending on what the task is. It's usually "more correct"; but in this very limited case scenario, regex actually works fine (and possibly faster). – Amber Sep 25 '10 at 17:21

Pretty straightforward (and folks, because he's asking for things with only whitespace between them, not nested tags or attributes or any of that, a parser isn't necessary in this case...)

/<p>\s+<\/p>/

/<p>\s+<br\/>/
