Parsing quoted string

[Jon-Hilbert]

Trying to design a parser to handle some legacy yaml. Problems:

1. how to handle "escaped" quotes in a string

e.g. 'You''re at fork in path.'

I am unable, based on the documentation, to figure out how to manage the double single-quote marks. I'm sure there's a clear way to do this, but I'm struggling. I would like the parser to return the unquoted string, e.g.

You're at fork in path.

2. since yaml is indentation aware, is there a way for me to determine the length of whitespace that is skipped at the beginning of a line? I want to be able to absorb all lines with the same level of indentation as a whole. I may figure this out in the next day or so, but any elegant suggestions would be appreciated.
