尝试解析CSS中的图像,但在压缩的CSS文件上使用时,regex会中断

I'm parsing image paths from CSS files for a project I'm working on and the following expression works fine provided the CSS file in question hasn't been compressed/minified.

Here's the expression that I'm using:

"/url\((.+)\)./"

When I use it with preg_match_all() against CSS such as the inline compressed CSS on Google's homepage it returns on result with the entire inline CSS block. What am I missing in the expression that's causing this to fail?

Add a ? after the + to make the match non-greedy: url\((.+?)\).

Alternatively, match the character class that just excludes the right paren: url\(([^)]+)\).

That second one is actually much faster, btw
