正则表达式选择两个“字符串”

Question

我有一个文件列表，当有人启动程序时，它将获得“普通文件”，当有人进行全面检查时，它将获得“完整检查文件”。

我尝试过以下表达式

(?=[normalFiles])(.*?element(?:(?!\|).)*)(?![/normalFiles])

仅在[normalFiles]和[/normalFiles]之间获取文件名，但它也会在[FullCheckFiles]和[/FullCheckFiles]之间获取文件名。

Answer 1

您对lookaround使用了错误的符号。积极的向后看是(?<=x)，而积极的向前看是(?=x)。此外，[和]用于表示正则表达式中的字符类，因此如果它们以文字形式出现，则需要将它们转义。

(?<=\[normalFiles\])(.*?)(?=\[/normalFiles\])

编辑：我正在使用以下代码进行测试：

var match = Regex.Match(filesList, @"(?<=\[normalFiles\])(.*?)(?=\[/normalFiles\])", 
                        RegexOptions.Singleline);
if (match.Success)
    Console.WriteLine(match.Value);

Answer 2

您可以使用：

(?:\[normalFiles\])((\n|.)*)(?=\[\/normalFiles\])
