> /A [.//C/@name ="something"]
> 1) Is the blank space between /A and [.//C/@name ="something"] significant?
no

it's one expression, made up of various subexpressions, as is 1 + 2, so
it depends quite what you mean.

Select all A elements that are the child of the document root [note]
That has a descendent element named C
that has an attribute with name name and value "something"
note
there
will be at most one element child of / in a well formed document, although the
Xpath data model potentially allows processing of fragments with more
than one top level element)

I have no idea what you mean here, so I can't really comment. The value
of the expression is a node set which will consist of zero or more
element nodes, (at most 1 if the input is well formed).
