The previous setup would consume too much. For example the following HTML:
<a><!--foo--><b><!--bar--></b></a>
would result in the following T_COMMENT token:
"foo--><b><!--bar"
The new setup requires the marking of a start position. I'm not a huge fan of
this but there doesn't appear to be a way around this.
Namespaces aren't scoped per document but instead per element, thus this method
doesn't make that much sense. This also fixes the remaining, failing XPath test.
The method XPath::Evaluator#node_matches? now has a special case to handle
"type-test" nodes. This in turn fixes a bunch of failing tests such as those for
the XPath query "parent::node()".
Unlike what I thought before syntax such as "node()" is not a function call.
Instead this is a special node test that tests the *types* of nodes, not their
names.
The lexer doesn't lex things correctly due to "//" and "/" both being separate
rules. As a result the lexer emits two T_SLASH tokens for queries such as
".//foo".
This separates namespace handling into namespace names and namespace objects.
The namespace objects are retrieved from the element an attribute belongs to.
Once retrieved the namespace is cached, due to the overhead of retrieving
namespaces in large documents.
The old code used for generating Object#inspect values has been ripped out (for
the most part). The result is a non indented but far more compact #inspect
output. The code for this is also easier and doesn't break the signature of
Object#inspect.
This also comes with some small cleanups regarding
XPath::Evaluator#node_matches?. This change removes the need to, every time,
also use can_match_node?() to prevent NoMethodError errors from popping up.
The previous commit was nonsense as I didn't understand XPath's "following" axis
properly. This commit introduces proper tests and a note for future me so that I
can implement it properly.
