Hello,

I need to remove all of the comments in a php file that is over 4000 lines long.

The comments consist of both types /**/ and //

I have a regular expression for the /**/ part :- [code sec below]

How can i remove the // comments from the document using Dreamweavers (unix like) regexes?
/\*[\S\s]+?(?=\*/)\*/

Tested with DW CS4:
(?:^|\n)[^\S\r\n]*(?://[^\r\n]*|/\*(?:(?!\*/)[\S\s])*\*/[^\r\n]*)

Unfortunately, this crashes Dreamweaver CS3 - I haven't moved over to CS4 as yet because of the transition with plugins.

When the regexe runs it clears only some of the comments but looks as though it gets stuck.

What would cause this?

Not sure, if you can attach a .txt file example of what crashes CS3 I can try it with CS4.

Cool, so it works in CS4.

How do you find CS4 in comparison to CS3?

I moved from MX2004 to CS4 so I don't have experience with CS3.  I haven't found anything with CS4 that I dislike but I code more than I design.

Thanks for the question and the points.

No trouble, same here from the coding angle - much cleaner & quicker.

Take care
