Proper handling of decimals for string() calls.
...
When calling the string() XPath function floats with zero decimals (10.0, 5.0,
etc) should result in a string without any decimals. Ruby converts 10.0 to
"10.0" whereas XPath expects "10".

Revert "Return XPath integers as actual integers."
...
The particular case of string(10) having to return "10" instead of "10.0" will
be handled separately. Returning integers breaks behaviour/expectations
elsewhere.
This reverts commit 431a253000

Support for the XPath concat() function.
2014-08-23 20:24:18 +02:00
431a253000
Return XPath integers as actual integers.
...
This is to ensure that calls such as string(10) return "10" and not "10.0". It
also saves integer -> float conversions when they're not needed.
2014-08-23 20:22:58 +02:00

Support for the XPath local-name() function.
2014-08-21 10:21:02 +02:00
2deb7a6d84
Support for the XPath id() function.
...
This comes with the limitation that it *always* uses the "id" attribute. This is
due to Oga not supporting DTD parsing/evaluation.
2014-08-20 21:06:35 +02:00
d351bc26cc
Support for the XPath count() function.
2014-08-20 10:16:06 +02:00

XPath support for last() + evaluator docs.

I really dislike using a stack as it introduces an internal state. Sadly there
doesn't seem to be an easy way around this.

Fixed lexing of XML CDATA tags.
2014-08-15 20:47:58 +02:00
81edce2eb8
Fixed lexing of XML comments.
...
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.
2014-08-15 20:42:32 +02:00
4d7f224892
Support for the XPath text() type test.
2014-08-15 10:46:00 +02:00

Use a new base class for XML text nodes.

The classes Text, Cdata and Comment now extend CharacterData instead of Text.

Added XML::Element#text_nodes.

This method returns all the text nodes directly nested in an element.
2014-08-15 10:07:49 +02:00
d0092b434d
Removed Document#available_namespaces.
...
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.
2014-08-14 23:12:33 +02:00
d34e4697de
Match node types in node_matches?
...
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()".
2014-08-14 22:54:19 +02:00

6ad5170476
Support for lexing/parsing XPath type tests.
...
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.
2014-08-14 21:51:58 +02:00

Basic support for the XPath node() function.
2014-08-14 18:17:08 +02:00
f2fe2a4b47
Failing XPath spec for double slashes.
...
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 is still a bit rough on the edges but already way better than the broken
setup I had before.
2014-08-11 00:41:36 +02:00
04cbbdcf9e
Proper namespace support for attributes.
...
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.

Ripped out inspect fuckery.
...
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.

The usage of `parent::node()` is not yet supported.
2014-08-05 09:34:57 +02:00
a1f80b4995
Support for the "following-sibling" axis.
...
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.
2014-08-04 21:51:51 +02:00

Parse bare XPath node tests as child axes.
...
When parsing a bare node test such as "A" this is now parsed as following:
(axis "child" (test nil "A"))
Instead of this:
(test nil "A")
According to the XPath specification both are identical and this simplifies some
of the code in the XPath evaluator.

Revert "Lex XPath axes without a node test."
...
Upon further investigation this change turned out to be useless. Nokogiri/libxml
does not allow the use of long axes without tests, instead it ends up
lexing/parsing such a value as a simple node test.
This reverts commit f699b0d097

Use XML::Attribute for element attributes.
...
Instead of using a raw Hash Oga now uses the XML::Attribute class for storing
information about element attributes.
Attributes are stored as an Array of XML::Attribute instances. This allows the
attributes to be more easily modified. If they were stored as a Hash you'd not
only have to update the attributes themselves but also the Hash that contains
them.
While using an Array has a slight runtime cost in most cases the amount of
attributes is small enough that this doesn't really pose a problem. If webscale
performance is desired at some point in the future Oga could most likely cache
the lookup of an attribute. This however is something for the future.
