Yorick Peterse 1fdf876a93 Tweaked docs of the XPath code a bit. 2014-09-04 10:17:32 +02:00
Yorick Peterse d8e2b97031 Tweaked docs of the XML parsers. 2014-09-04 09:34:59 +02:00

Yorick Peterse 404ae51fd5 Added a basic set of examples on using Oga. 2014-09-04 00:24:13 +02:00
Yorick Peterse 6c90749ec6 Updated XPath node in the README. 2014-09-04 00:15:41 +02:00
Yorick Peterse fbf3ae6e36 Manually increment XPath indexes.
This ensures that the index is only incremented for elements that match a node
test.

Yorick Peterse 81a62a6f00 Added XML::Attribute#text
This allows attributes to also be used for axes such as "=".

Yorick Peterse 9b8e9f49c6 Support for lexing empty attribute values.
This ensures that Oga can lex the following properly:

    <input value="" />

Previously Ragel would stop upon finding the empty string. This was caused due
to the string rules being declared as following:

    string_dquote = (dquote ^dquote+ dquote);
    string_squote = (squote ^squote+ squote);

These rules only match strings _with_ content, not without. Since Ragel stops
consuming input the moment it finds unhandled data this resulted in incorrect
tokens being emitted.

Yorick Peterse dc5874f5aa Show XML parsing errors when using IO as input.
Previously this wouldn't display anything due to the IO object being exhausted.
To fix this the input has to be wound back to the start, which means re-reading
it. Sadly I can't think of a way around this that doesn't require buffering
lines while parsing them (which massively increases memory usage).

Yorick Peterse d67f43508d Use #each_line instead of #lines.
IO#each_line is deprecated so lets not rely on it.

Yorick Peterse bd31379c85 Fixed processing of nested predicates.
This ensures that nested predicates and functions that depend on predicates are
processed correctly.

Yorick Peterse 3196050978 Specs for nested predicates & self axis. 2014-09-03 20:55:55 +02:00
Yorick Peterse e858b54c58 Use nested node stacks for predicates.
This ensures the current context node is set correctly when using the "self"
axis inside a path that's inside a predicate, e.g.

    foo/bar[baz/. = "something"]

Here the "self" axis should refer to foo/bar/baz, _not_ foo/bar.

Yorick Peterse 2b96d65103 XPath "self" axis inside predicates.
The "self" axis should use the current context node when inside a predicate.

Yorick Peterse 49ddebf358 Tighten lexing of T_TEXT nodes.
Thanks to some heavy rubberducking with @whitequark the lexer is now a little
bit better at lexing T_TEXT nodes. For example, previously the following could
not be lexed properly:

    "foo < bar"

There might still be some tweaking to do but we're getting there.

Yorick Peterse 84d6ba96c2 Benchmarks for comparing Oga with others.
This includes two benchmarks: one for parsing XML and one for evaluating XPath.

Benjamin Klotz 0b096dfe25 Use proper create_makefile
Using create_makefile('liboga/liboga') will compile liboga.so into
path-to-gem/lib/liboga/ and therefore require_relative in oga.rb will fail.
Therefore the right parameter for create_makefile is 'liboga' ->
path-to-gem/lib/liboga.so
