Given the text:
test=this=that=more text follows
I want to choose:
test=
I tried the following regular expressions
(\S+)=(\S.*)
(\S+)?=
[^=]{1}
...
Thank you all.
// matches "test=, test"
(\S+? )=
or
// matches "test=, test" too
(\S[^=]+)=
You should consider using the first version. Given your string “test = this = that = more text following”, version 1 will match test = this = that = and then continue to parse to the end of the string. Then it will backtrack , And find test = this =, continue backtracking, find test =, continue backtracking, and then select test = as its final answer.
Version 2 will match test = and then stop. You can use the larger I see efficiency improvements in the search, such as multi-line or entire document matching.
I am sure this is easy, but I tried many changes, but still can’t meet my needs . Things are too greedy, I can’t let it stop being greedy.
