[Solved] How to parse txt file from middle to particular string using C++?

Question

string::find() has an overload that specifies the position to start the search. So simply start a second search, starting at the end of <ID>, to look for </ID>. You are after what comes in between the two. Pretty simple really.

However, as suggested elsewhere, there are a lot of XML parsers out there. Using a full XML parser would be recommended if the input file could have some variations.
