Using regex to match the start and end of a media query, but not the content inbetween

问题

I'm using the htmlcompressor (https://code.google.com/p/htmlcompressor/#For_Non-Java_Projects) to minify HTML content (HTML email templates) as well as inline CSS within the head section of the document. I'm running this via Command Line on Windows:

java -jar /path/to/htmlcompressor --preserve-comments --preserve-line-breaks --compress-css --remove-surrounding-spaces min -p /path/to/minify-preserve.txt --type html original-html -o minified-output.html

Within this document there are two media queries which I need to prevent the htmlcompressor from modifying due to syntax issues. I was looking around and found this regex rule:

@media[^{]+\{([\s\S]+?})\s*}

It however matches the media queries and the contents between, ideally, I need it to match only the starting block and end brackets, so its maintains spaces in these areas for valid syntax.

Would this be achievable with regex? I am limited to regex only as its the only method of creating preservation rules, as per the documentation.

Thanks.

You'r regular expresion is almost right. but (backward slash) is missing before closing curly brace

@media[^{]+\{([\s\S]+?\})\s*\}
