Yorick Peterse b74f8dc1a3 Removed compiler arity spec
This spec isn't very useful and breaks on 1.9 due to it apparently
handling arity values differently.

Yorick Peterse 70bea2071c Fixed ancestor-or-self relative to attributes
Per libxml behaviour this axis shouldn't match attributes when using
"ancestor-or-self::*".

This makes it easier to get more natural spec descriptions without

Yorick Peterse 365a9e9fa9 Replace (path) nodes with nested nodes
This changes the XPath AST so that every segment in a path (e.g.
foo/bar) is parsed as a child node of the node that precedes it. For
example, take the following expression:

    foo/bar

This used to be parsed into the following AST:

    (path
      (axis "child" (test nil "foo"))
      (axis "child" (test nil "bar")))

This is now parsed into the following AST:

    (axis "child"
      (test nil "foo")
      (axis "child"
        (test nil "bar")))

This new AST is much easier to deal with in the XPath::Compiler class,
especially when trying to ensure that each segment operates on the
correct input.

This commit also fixes parsing of type tests with predicates, such as:

    comment()[10]

This used to throw a parser error.

Yorick Peterse 37ac844ebe Fixed spec for sum() in a predicate
The return value of sum() should be used as a NodeSet index, not merely
just a truthy value.

Yorick Peterse 94ec1b5f5d Corrected the last() compiler spec
This spec didn't match the correct nodes due to `1 < last()` always
evaluating to true in this particular case.

Yorick Peterse 4b50a161ed Wrap all compiler assignments in begin/end
This is much safer than having to explicitly call "wrap" in a potential
large amount of places.

Yorick Peterse 54473d9865 Allow followed_by to take a block
This removes the need for a lot of local variables in the Compiler
class, at the cost of some extra indentation levels.

Yorick Peterse e3b45fddfc to_float support for non String values 2015-08-19 20:14:22 +02:00
Yorick Peterse 07b52fb48a Added Ruby::Node#not
This is a shortcut for "!foo". Using this method one doesn't have to
worry about how the "!" operator binds. For example, this:

    !foo.or(bar)

would be parsed/evaluated as this:

    !(foo.or(bar))

when instead we want it to be this:

    (!foo).or(bar)

Using explicit parenthesis leads to ugly code, so now we can do this
instead:

    foo.not.or(bar)

Yorick Peterse 2eb12eced6 XPath compiler support for all operators
Some specs still fail due to true()/false() not being implemented but
the operators themselves should work just fine.
