基于正则表达式的字符串拆分

Question

I am trying to split a string which looks like this:

1.2.1Title of the Chapter

(There is no space between '1' and 'T')

I want the output as:

String 1: 1.2.1
String 2: Title of the chapter

I tried this:

strParagraphs = 1.2.1Title of the chapter;
string[] lines1 = Regex.Split(strParagraphs, "(\\d{1}).(\\d{1}).(\\d{1})");
also
string[] lines1 = Regex.Split(strParagraphs, "^\\w+");

I could not arrive at my desired output. Can someone please suggest, where is it that I am going wrong?

Many thanks

Answer 1

This should work like a charm:

string[] lines = Regex.Split(inputstring, @"(\d+.\d+.\d+)");

Result:

1.2.1 
Title of the Chapter 

Note: the result may differ depending on .net version!
