我有一个文本字符串，其中包含一个重复模式，每个重复之间用.(点)字符隔开.模式may以_123结尾(下面是一个数字序列)，我想在专用捕获组中捕获这些数字.
The RegEx (ECMAScript) I have built mostly works:
https://regex101.com/r/iEzalU/1
/(label(:|\+))?(\w+)(?:_(\d+))?/gi
然而，(\w+)部分表现得贪婪，并超越了(?:_(\d+))?部分.
添加?以生成\w+非贪婪(\w+?)有效，但现在我 for each 与\w匹配的角色都有一个捕获令牌
How can I make this regex such that \w+ acts greedy but still does not overtake the _(\d+) part?
Otherwise, is it possible to capture all tokens matched by the non-greedy \w+?, as a single match? (some capturing/non-capturing groups magic?)
