我有一个场景，我需要分开弦-
"Tom told Jerry, \"You there!\nCome here.\" \nThen Jerry responded, \"Not today.\""
在这里，我必须根据换行符拆分字符串，但如果换行符包含在双引号内("\n")，则不包括拆分.
上述字符串的输出应如下所示-
Tom told Jerry, "You there!\n Come here."
Then Jerry responded, "Not today."
我的代码导致-
**Tom told Jerry,
You there!
Come here.
Then Jerry responded,
Not today.**
但输出应该是-
**Tom told Jerry,
"You there!\nCome here."
Then Jerry responded, "Not today."**
您可以使用
var text = "Tom told Jerry, \"You there!\nCome here.\" \nThen Jerry responded, \"Not today.\"";
var pattern = "(?:\"[^\"]*\"|[^\n\"])+";
var result = Regex.Matches(text, pattern);
foreach (Match m in result)
{
Console.WriteLine("'" + m.Value + "'");
}
请看C# demo.
Details:
(?:\"[^\"]*\"|[^\n\"])+ - one or more occurrences of
\"[^\"]*\"-a "+除"+a "以外的任何零个或多个字符|-或[^\n\"]-除换行符和"之外的任何字符.
