Answer 1

This is an example:

/*/*[contains(., "'") and contains(., '"') ]/text()

    I am reading "Harry Potter"
    I am reading 'Harry Potter'

Your problem may be that you are not able to specify this XPath expression as string in the programming language that you are using -- this isn't an XPath problem but a problem in your knowledge of your programming language.
