Added require() for StringIO.
...
This is needed since the lexer checks if the input is a StringIO instance.

First pass at using the NodeSet class.
...
The documentation still leaves a lot to be desired and so does the API. There
also appears to be a problem where NodeSet#remove doesn't properly remove all
nodes from a set. Outside of that we're making slow progress towards a proper
DOM API.

Indexing of NodeSet instances.

Similar to arrays the NodeSet class now allows one to retrieve nodes for a
given index.

NodeSet#push should not take node ownership.
2014-06-26 09:37:30 +02:00
15fa7a2068
Remove explicit index tracking of NodeSet.
...
Instead the various nodes can use NodeSet#index (aka Array#index) instead. This
has a slight performance overhead on very large (millions) of nodes but should
be fine in most other cases.

Corrected XPath operator precedence.
...
The previous commit didn't fully change the operator precedence according to
the XPath 1.0 specification. Also thanks to @whitequark for clearing up a few
things about Racc's operator precedence system.
2014-06-23 00:30:42 +02:00
a440d3f003
Fixed XPath operator precedence.
...
Apparently using multiple `left` rules with T_AND and T_OR being separate
solves this problem. Riiiiight....
2014-06-23 00:15:43 +02:00

Parsing support for more XPath operators.

This still messes up some tests due to botched token precedence (by the looks
of it).

Lex XPath operators using individual tokens.

Instead of lexing every operator as T_OP they now use individual tokens such as
T_EQ and T_LT.

Support for lexing XPath wildcard expressions.

To support this we need to require whitespace around the "*" operator. This is
not ideal but it will do for now.
2014-06-01 23:01:24 +02:00

Basic working XPath lexer.

This doesn't lex everything of the XPath specification just yet and needs more
tests.

Rewind IO input upon resetting the lexer.
2014-05-26 00:33:20 +02:00
629dcd3fe6
Support for IO inputs in the lexer.
...
Using IO/StringIO objects one can parse large XML files without first having to
read the entire file into memory. This can potentially save a lot of memory at
the cost of a slightly slower runtime.
For IO like instances the lexer will consume the input line by line. If a
String is given it's consumed as a whole instead. A small side effect of
reading the input line by line is that text such as "foo\nbar" will be lexed as
two tokens instead of one.
Fixes #19 .

6b9d65923a
Use a method for getting input in the XML lexer.
...
Instead of directly accessing the `data` instance variable the C/Java code now
uses the method `read_data`. This is part of one of the various steps required
to allow Oga to read data from IO like instances. It also means I can freely
change the name of the instance variable without also having to change the
C/Java code.

The tokens T_COMMENT_START, T_TEXT and T_COMMENT_END have been merged into a
single token: T_COMMENT. This simplifies both the lexer and the parser.

This comes with a little bit of memory overhead but this should be minor in
most cases.

This process is quite a bit slower compared to setting instance variables
directly.

Manually bootstrap JRuby after all.

After discussing this with @headius I've decided to do this the manual way
anyway. Apparently the basic load service stuff is deprecated and not very
reliable.
