Properly fixed AST for first-of-type/last-of-type
...
This requires keeping track of the current element being processed. This in turn
allows the usage of count() + preceding-sibling/following-sibling.

Evaluate XPath predicates for every context node.
...
Instead of evaluating a predicate once for all context nodes, they should
instead be evaluated separately per context node.

Functions can't be used in combination with axes, so I'll just need to fix the
position() function to work properly.

Fixed XPath AST for :last-of-type

This should count following nodes, not merely the position.

Fixed CSS evaluation of :first-of-type
...
The old XPath "position() = 1" would work in Nokogiri due to the way they
retrieve descendants. In Oga however this would simply always return the first
node.
To fix this Oga now counts the amount of preceding siblings that match the same
full name.

Wrap predicate AST nodes _around_ other nodes.
...
This means that "foo[1]" uses this AST:
(predicate (test nil "foo") (int 1))
Instead of this AST:
(test nil "foo" (int 1))
This makes it easier for the XPath evaluator to process predicates correctly.

duplication and odd context blocks.

Added XML::NodeSet#==
...
This method can be used to compare two NodeSet instances. By using
XML::NodeSet#equal_nodes?() the need for exposing the "nodes" instance variable
is also removed.

Removed support for CSS such as "|X"
...
This expression could be used to get all elements that _don't_ have any
namespace. The problem is that this can't be expressed as just a node test,
instead the resulting XPath would have to look something like the following:
X[local-name() = name()]
However, since the XPath predicates are already created for pseudo classes and
such, also injecting the above into it would be a real big pain. As such I've
decided not to support it.

XPath idents can't start with a star.

That is, names such as "*foo" are not valid. This was most likely a typo in the
first place.

Allow XPath idents to start with an underscore.

This is valid in XML so XPath should support it as well.

Use the descendant axis for CSS selectors.
...
Instead of using "descendant-or-self" Oga will use "descendant". This ensures
that expressions such as "foo *" don't return a set also including the "foo"
element.
Nokogiri solves this problem in a somewhat different way by using //foo//* for
the CSS expression "foo *". While this works in Nokogiri the expression
"descendant-or-self::node()" is slow as a snail in Oga (due to its nature of
retrieving _all_ nodes first). By using "descendant" we can work around this
problem.
2014-11-05 00:22:09 +01:00
602f2fe8bb
Apply node() type tests to the document too.
...
When running XPath queries such as "self::node()" the result should be a set
containing the document itself. This in turn fixes expressions such as
descendant-or-self::node()/a.
