Answer 1

要求在教区内找到两个上限:

([A-Z]{2})

重新定位取决于你使用的技术。 http://msdn.microsoft.com/en-us/library/system.text.tableexpressions.regex.replace.aspx”rel=“nofollow” 。

  string input = "some text";
  string pattern = @"([A-Z]{2})";
  string replacement = "replace value";
  Regex rgx = new Regex(pattern);
  string result = rgx.Replace(input, replacement);

Answer 2

http://rubular.com

([A-Z]{2})

Answer 3

In Perl syntax:

s/([A-Z]{2})//g

This will replace any parentheses with two capital letters inside it with an empty string. If you want to replace them with some other string, just fill in the (empty) space between the last two slashes, e.g.

s/([A-Z]{2})/replacement goes here/g

Answer 4

([A-Z]{2})

将与你的模式相称。

Answer 5

是的,而且非常简单:

s/([A-Z][A-Z])/replacement/
