如何从字符串中提取“程序名称”。该字符串将如下所示:

%O0033(SUB RAD MSD 50R III)G91G1X-6.4Z-2.F500 G3I6.4Z-8。G3I6.4 G3R3.2X6.4F500 G91G0Z5。G91G1X-10.4 G3I10.4 G3R5.2X10.4 G90G0Z2。M99%

程序名称为(SUB RAD MSD 50R III)。将结果存储在另一个字符串中就可以了。我正在学习功能强大的工具,所以对您答案的任何解释将不胜感激。

以下正则表达式提取括号之间的所有内容:

PS> $prog = [regex]::match($s,'\(([^\)]+)\)').Groups[1].Value
PS> $prog
SUB RAD MSD 50R III


Explanation (created with RegexBuddy)

Match the character '(' literally «\(»
Match the regular expression below and capture its match into backreference number 1 «([^\)]+)»
   Match any character that is NOT a ) character «[^\)]+»
      Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+»
Match the character ')' literally «\)»
