我该如何写一个正则表达式来匹配首尾之间的所有内容？

Question

I try to match multiple values between quotes (these values can be anything but spaces) the best I can achieve is to match everything between the first and the last quote

I already checked many SO answers, yet I cannot make it work

here is the regex

\[\[\[(\w*img\w*)\s(\w*id|url\w*)+="([^"]|.*)"\]\]\]

here is the string I try to match (values are numbers but I could have urls or anything similar)

[[[img id="37" w="100" h="70"]]]

I should get all parameters and their respecting values, but I get only one parameter with the value beeing 37" w="100" h="70

I know I am close, but this one is tricky

I don't think you need all the \\w . And I also would suggest splitting the task in two parts as suggested in a comment.

However, I also see an option in doing it in just one step :

\[\[\[img(?:\s(\w+)="([^"]+)")?(?:\s(\w+)="([^"]+)")?(?:\s(\w+)="([^"]+)")?\]\]\]

This is basically the wrapper [[[]]] , a normal character part img and then (?:\\s(\\w+)="([^"]+)")? repeated as many times as you expect attributes to appear. (\\w+) matches the name of the attribute and ([^"]+) its value.
