I would like to use UltraEdit regular expression (perl) to replace the following text

  • 0

I would like to use UltraEdit regular expression (perl) to replace the following text with some other text in a bunch of html files:

<style type="text/css">

#some-id{}

.some-class{}

//many other css styles follow

</style>

I tried to use <style type="text/css">.*</style> but of course it wouldn’t match anything because the dot matches any character except line feed. I would like to match line feed as well and the line feed maybe either \r\n or \n.

How should the regular expression look like?

Many thanks to you all.

    In UltraEdit, you need to prepend (?s) to your regex to make the dot match newline.

    I. e., search for 

    (?s)<style type="text/css">.*?</style>

    I’ve also made the quantifier lazy (.*?) because otherwise you would match everything from the first <style> to the last </style> in your entire file.

    Also be advised that this is a flaky solution because regular expressions can’t parse HTML reliably if at all. In UltraEdit, that’s all you have – a scripting language and a parser would be better, but if it works in your case, then great. Just make sure you don’t match more (or less) than you wanted (think //comment containing a </style> tag).
