Space before the :.

Could you elaborate the change?

[SergioCrisostomo]

@arian sure, should have done that in the first place, sorry.

This change only applies to cases where contents has boolean value false, and so the change is from

"<\/?" + tag + "([^>]+)?>";

to

"<\/?" + tag + "\/?>|<" + tag + "[\\s|\/][^>]*>"

and in cases where tag has boolean value false, tag will be '\\w+'.

As it was str.stripTags("b") would also strip <br/> tags since the regex would be <\/?b([^>]+)?>.

So the first alternative in the new regex suggestion is for simpler tags (closing or self-closing), and the second alternative is for self-closing, opening, and tags with attributes. This way it will never match a letter after the tag that was passed to the method.
