Regular expression needed for PHP

Question

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!

Answer 1

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 :)

Answer 2

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\/>/
