You’re going to have to be a little more specific - the regular
expression /0/ matches the first string and not the second but that’s
probably not what you wanted.

The thing you’re asking is not very specific, there’s a lot to be
interpreted, but this might be what you are looking for: \d{3}\d{3}
\d{4}

Well, Google found this one pretty quick:
http://www.mizar.dk/XPath/Default.aspx

Maybe it can find others, too, if that one doesn’t work for you.

2. In Ruby there is a command called ‘require’. Explain what this
command means and write an example of how it is used to include a Ruby
Gem in a file.
