Fixed node() type test for the XPath compiler
...
This ensures the handler behaves the same as in the old XPath evaluator.

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

This ensures that any nested code uses the right 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.

Removed useless YARD docs from the XPath compiler

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.

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.

Basic support for compiling XPath to Ruby
...
This currently comes with exactly 0% test coverage. Once I've
implemented all required handler methods I'll be updating the current
evaluator tests to use the compiler instead. This removes the need for
writing an entirely new set of tests.
Currently the compiler is only capable of compiling basic expressions
such as "foo", "foo/bar" and "foo[@x="y"]/bar".
