Yorick Peterse b688c6dc1b Support for the XPath concat() function. 2014-08-23 20:24:18 +02:00
Yorick Peterse 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.

Yorick Peterse b316fd3e1c Support for the XPath string() function. 2014-08-22 11:06:10 +02:00
Yorick Peterse ff8a4ad3aa Ignore comment nodes in NodeSet#text. 2014-08-22 11:05:39 +02:00
Yorick Peterse 99be3182ae Support for evaluating XPath floats. 2014-08-22 10:59:03 +02:00
Yorick Peterse 6ac3408a71 Match all node types when using node()
Previously this would only match element and text nodes.
2014-08-22 10:58:36 +02:00
Yorick Peterse da09f1296c Support for using namespace-uri() with attributes. 2014-08-21 22:36:18 +02:00
Yorick Peterse 0d41693bfc Support for using name() with attributes. 2014-08-21 21:05:06 +02:00
Yorick Peterse acc056eea4 Support for using local-name() on attributes. 2014-08-21 21:03:28 +02:00
Yorick Peterse 1dd6416bea Basic support for the XPath name() function. 2014-08-21 20:47:20 +02:00
Yorick Peterse e7019ceb4c Renamed context_node to function_node. 2014-08-21 19:06:14 +02:00
Yorick Peterse 8cc0db2283 Support for the XPath namespace-uri() function. 2014-08-21 19:02:41 +02:00
Yorick Peterse 9e20b5ca3e Support for the XPath local-name() function. 2014-08-21 10:21:02 +02:00
Yorick Peterse 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
Yorick Peterse d351bc26cc Support for the XPath count() function. 2014-08-20 10:16:06 +02:00
Yorick Peterse 709fa365e0 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.

Yorick Peterse e0895be675 Better setup for XPath predicates.
This allows filtering of nodes by indexes (e.g. using last() or a literal
number) and uses the correct index range (1 to N in XPath). The function
position() is not yet supported as this requires access to the current node,
which isn't passed down the call stack just yet.
2014-08-19 19:56:56 +02:00
Yorick Peterse 202f74a8eb on_call_last() should return an index, not a node. 2014-08-19 19:56:41 +02:00
Yorick Peterse 423af37422 Basic support for the XPath last() function. 2014-08-18 19:00:32 +02:00
Yorick Peterse 2817784e6b Support for the XPath pipe operator. 2014-08-17 22:04:08 +02:00
Yorick Peterse d1735750c1 Only store unique nodes in XML::NodeSet.
It's called a "set" after all.
2014-08-17 22:03:44 +02:00
Yorick Peterse bb503728af XPath support for processing instructions. 2014-08-16 22:37:57 +02:00
Yorick Peterse 56341b5585 Cleaned up lexing of comments/cdata.
Thanks to @whitequark for suggesting the use of the "--" operator.

Yorick Peterse 0d7609da88 Support for parsing XML processing instructions. 2014-08-15 22:23:26 +02:00
Yorick Peterse 2c488f92be Cleaned up marking of comments/cdata tags. 2014-08-15 22:05:09 +02:00
Yorick Peterse 8f4eaf3823 Lexing of XML processing instructions. 2014-08-15 22:04:45 +02:00
Yorick Peterse ccd95d69d8 Support for the XPath comment() test. 2014-08-15 20:49:13 +02:00
Yorick Peterse 4e8cca258c Fixed lexing of XML CDATA tags. 2014-08-15 20:47:58 +02:00
Yorick Peterse 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
Yorick Peterse 4d7f224892 Support for the XPath text() type test. 2014-08-15 10:46:00 +02:00
Yorick Peterse 14aa420091 Use a new base class for XML text nodes.
The classes Text, Cdata and Comment now extend CharacterData instead of Text.
2014-08-15 10:43:16 +02:00
Yorick Peterse 24bc84e15e 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
Yorick Peterse 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
Yorick Peterse 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
Yorick Peterse a437d67573 Renamed node_type to type_test. 2014-08-14 22:35:41 +02:00
Yorick Peterse 05f6fc2f8d Implement node() as a type test, not a function. 2014-08-14 22:30:14 +02:00
Yorick Peterse 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
Yorick Peterse 23441bb5a4 Basic support for the XPath node() function. 2014-08-14 18:17:08 +02:00
Yorick Peterse a133b923a2 Only emit extra T_SLASH tokens for "//". 2014-08-13 01:28:43 +02:00
Yorick Peterse 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".
2014-08-13 00:37:12 +02:00
Yorick Peterse f4ae83498e Eval specs for the self axis short form. 2014-08-11 09:35:01 +02:00
Yorick Peterse ffcefa92a7 Eval specs for the descendant-or-self short axis.
This currently fails due to the node() function not being implemented just yet.
2014-08-11 09:33:09 +02:00
Yorick Peterse aef3e0f27e Evaluator specs for the attribute axis short form. 2014-08-11 09:32:45 +02:00
Yorick Peterse 4d956c9ef0 Support for the XPath "namespace" axis. 2014-08-11 00:58:57 +02:00
Yorick Peterse 873bd82273 Stricted matching of namespaced elements. 2014-08-11 00:47:07 +02:00
Yorick Peterse 78da274452 Updated XPath specs for better namespace handling. 2014-08-11 00:42:06 +02:00
Yorick Peterse 33c28f633b Proper namespace support for elements.
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
Yorick Peterse 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.

Yorick Peterse fe8f77cf45 Basic work for supporting namespace URIs. 2014-08-08 19:03:42 +02:00
Yorick Peterse f002061aaa Extra type validation for XML::Element options. 2014-08-07 21:10:01 +02:00
