如何使用正则表达式拆分括号内用逗号分隔的字符串 [英] How to split string separated by a comma within the bracket using regex
问题描述
我的输入字符串:
message(hello){message = msg.hello;} xyz('Text1','Text2',Text3); asdgfd main.send(msg);
输出:
'Text1'
'Text2'
Text3
我需要从上面的字符串中匹配xyz('Text1','Text2',Text3)并需要获取每个字符串括号内的逗号(,)分隔的单词。任何人都可以给出正确的正则表达式吗?
我尝试过的事情:
我已经尝试但无法正确获取分离的值
老实说,我会用两个正则表达式:第一个提取逗号分隔值,这非常简单:
(?< = xyz\()。+?(?= \))
然后用逗号分割字符串,或用第二个简单的正则表达式解析它:
([^ ,] +?)(?=,|
)Wich为您提供单独匹配中的每个元素。
这样,laters更改是一个更容易解决的整个负载 - 复杂的正则表达式难以阅读甚至更难修改!
非正则表达式解决方案,不优雅,但是......
string s =message(hello){message = msg.hello;} xyz('Text1','Text2 ',Text3); asdgfd main.send(msg); ;
var parts = s.Split(new string [] {xyz(,);},StringSplitOptions.RemoveEmptyEntries)
.Where(x => x.Contains( ,))
.SelectMany(x => x.Split(new string [] {,},StringSplitOptions.RemoveEmptyEntries))
.ToList();
My Input String :
"message(hello) {message= msg.hello;}xyz('Text1','Text2', Text3);asdgfd main.send(msg);"
Output:
'Text1'
'Text2'
Text3
I need to match "xyz('Text1','Text2', Text3)" from the above string and need to get each word separated by a comma(,) within the bracket. Can anyone give the proper regex to do this?
What I have tried:
I have tried but cannot able to get that separated values properly
To be honest with you, I'd do it with two regexes: the first to extract the comma separated values, which is pretty trivial:
(?<=xyz\().+?(?=\))
Then either Split the string on commas, or parse it with a second, simple regex:
([^,]+?)(?=,|
)Wich gives you each element in a separate Match.
That way, laters changes are a whole load easier to work out - complex regexes are hard to read and even harder to modify!
Non-regex solution, not elegant, but...
string s = "message(hello) {message= msg.hello;}xyz('Text1','Text2', Text3);asdgfd main.send(msg);"; var parts = s.Split(new string[]{"xyz(", ");"}, StringSplitOptions.RemoveEmptyEntries) .Where(x=>x.Contains(",")) .SelectMany(x=>x.Split(new string[]{","}, StringSplitOptions.RemoveEmptyEntries)) .ToList();
