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)

XPath compiler Support for following-sibling
...
This is a direct port of the same handler used in the Evaluator class.
The code is a bit rough on the edges but this will be cleaned up in
upcoming commits.

Basic compiler support for descendant-or-self

The generated code isn't entirely correct which considering the tests do
pass means the tests need to be fixed too.

Use "node" for axis variables

XPath compiler support for operators in predicates

Previously the operator methods would ignore any blocks set by the
on_predicate family of methods.

Cleaned up compiler handling of axes/calls
...
Function call handlers don't receive a single AST node, instead they
receive the XPath arguments as separate method arguments.

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.

XPath::Compiler#compile specifies blocks for paths
...
Previously the on_path method itself would specify a block to use when a
node was matched. This makes it impossible to customize this behaviour
which is needed when a path is used in an operator or predicate. By
letting the #compile() method specify the block other handlers can
overwrite it.

Use each_ancestor for ancestor-or-self in XPath

The XPath compiler now uses XML::Node#each_ancestor for compiling the
"ancestor-or-self" axis.
2015-08-19 20:14:20 +02:00
52741a3b78
Added XML::Node#each_ancestor

This method can be used to walk through the ancestor tree of a Node.

db39b25546
XPath compiler support for ancestor-or-self
...
This also comes with some changes to the specs as the old behaviour of
the Evaluator was incorrect. The Evaluator would bail after matching a
single node but instead it's meant to continue until it runs out of
parent nodes.

XPath compiler support for predicates
...
This currently supports index predicates (e.g. "foo[10]") and predicates
using paths (e.g. foo[bar/baz]). The usage of boolean operators and more
complex expressions has not yet been tested as these are not yet
supported in the first place.
