## 0.1.3 - 2014-09-24
|
|
|
|
|
|
|
|
This release fixes a problem with serializing attributes using the namespace
|
|
|
|
prefix "xmlns". See <https://github.com/YorickPeterse/oga/issues/47> for more
|
|
|
|
information.

### SAX API
|
|
|
|
|
2014-09-16 12:49:42 +00:00
|
|
|
A SAX parser/API has been added. This API is useful when even the overhead of
|
2014-09-16 13:01:38 +00:00
|
|
|
the pull-parser is too much memory wise. Example:
|
|
|
|
|
|
|
|
class ElementNames
|
|
|
|
attr_reader :names
|
|
|
|
|
|
|
|
def initialize
|
|
|
|
@names = []
|
|
|
|
end
|
|
|
|
|
|
|
|
def on_element(namespace, name, attrs = {})
|
|
|
|
@names << name
|
|
|
|
end
|
|
|
|
end
|
|
|
|
|
|
|
|
handler = ElementNames.new
|
|
|
|
|
|
|
|
Oga.sax_parse_xml(handler, '<foo><bar></bar></foo>')
|
|
|
|
|
|
|
|
handler.names # => ["foo", "bar"]
|
|
|
|
|
|
|
|
### Racc Gem
|
2014-09-16 12:49:42 +00:00
|
|
|
|
|
|
|
Oga will now always use the Racc gem instead of the version shipped with the
|
|
|
|
Ruby standard library.
|
|
|
|
|
2014-09-16 13:01:38 +00:00
|
|
|
### Error Reporting
|
|
|
|
|
2014-09-16 12:49:42 +00:00
|
|
|
XML parser errors have been made a little bit more user friendly, though they
|
|
|
|
can still be quite cryptic.
|
|
|
|
|
2014-09-16 13:01:38 +00:00
|
|
|
### Serializing Elements
|
|
|
|
|
2014-09-16 12:49:42 +00:00
|
|
|
Elements serialized to XML/HTML will use self-closing tags whenever possible.
|
|
|
|
When parsing HTML documents only HTML void elements will use self-closing tags
|
2014-09-16 13:01:38 +00:00
|
|
|
(e.g. `<link>` tags). Example:
|
|
|
|
|
|
|
|
Oga.parse_xml('<foo></foo>').to_xml # => "<foo />"
|
|
|
|
Oga.parse_html('<script></script>').to_xml # => "<script></script>"
|
|
|
|
|
|
|
|
### Default Namespaces
|
2014-09-16 12:49:42 +00:00
|
|
|
|
|
|
|
Namespaces are no longer removed from the attributes list when an element is
|
|
|
|
created.
|
|
|
|
|
|
|
|
Default XML namespaces can now be registered using `xmlns="..."`. Previously
|
2014-09-16 13:01:38 +00:00
|
|
|
this would be ignored. Example:
|
|
|
|
|
|
|
|
document = Oga.parse_xml('<root xmlns="baz"></root>')
|
|
|
|
root = document.children[0]
|
2014-09-16 12:49:42 +00:00
|
|
|
|
2014-09-16 13:01:38 +00:00
|
|
|
root.namespace # => Namespace(name: "xmlns" uri: "baz")
|
|
|
|
|
|
|
|
### Lexing Incomplete Input
|
|
|
|
|
|
|
|
Oga can now lex input such as `</` without entering an infinite loop. Example:
|
|
|
|
|
|
|
|
Oga.parse_xml('</') # => Document(children: NodeSet(Text("</")))
|
|
|
|
|
|
|
|
### Absolute XPath Paths
|
2014-09-16 12:49:42 +00:00
|
|
|
|
|
|
|
Oga can now parse and evaluate the XPath expression "/" (that is, just "/").
|
2014-09-16 13:01:38 +00:00
|
|
|
This will return the root node (usually a Document instance). Example:
|
|
|
|
|
|
|
|
document = Oga.parse_xml('<root></root>')
|
|
|
|
|
|
|
|
document.xpath('/') # => NodeSet(Document(children: NodeSet(Element(name: "root"))))
|
|
|
|
|
|
|
|
### Namespace Ordering
|
2014-09-16 12:49:42 +00:00
|
|
|
|
|
|
|
Namespaces available to an element are now returned in the correct order.
|
|
|
|
Previously outer namespaces would take precedence over inner namespaces, instead
|
2014-09-16 13:01:38 +00:00
|
|
|
of it being the other way around. Example:
|
|
|
|
|
|
|
|
document = Oga.parse_xml <<-EOF
|
|
|
|
<root xmlns:foo="bar">
|
|
|
|
<container xmlns:foo="baz">
|
|
|
|
<foo:text>Text!</foo:text>
|
|
|
|
</container>
|
|
|
|
</root>
|
|
|
|
EOF
|
|
|
|
|
|
|
|
foo = document.at_xpath('root/container/foo:text')
|
|
|
|
|
|
|
|
foo.namespace # => Namespace(name: "foo" uri: "baz")
|
|
|
|
|
|
|
|
### Parsing Capitalized HTML Void Elements
|
2014-09-16 12:49:42 +00:00
|
|
|
|
|
|
|
Oga is now capable of parsing capitalized HTML void elements (e.g. `<BR>`).
|
|
|
|
Previously it could only parse lower-cased void elements. Thanks to Tero Tasanen
|
2014-09-16 13:01:38 +00:00
|
|
|
for fixing this. Example:
|
|
|
|
|
|
|
|
Oga.parse_html('<BR>') # => Document(children: NodeSet(Element(name: "BR")))
|
|
|
|
|
|
|
|
### Node Type Method Removed
|
2014-09-16 12:49:42 +00:00
|
|
|
|
2014-09-13 13:09:52 +00:00
|
|
|
The `node_type` method has been removed and its purpose has been moved into
|
|
|
|
the `XML::PullParser` class itself. This method was solely used by the pull
|
|
|
|
parser to provide shorthands for node classes. As such it doesn't make sense to
|
|
|
|
expose this as a method to the outside world as a public method.
|
|

|
|
|
## 0.1.1 - 2014-09-13
|
|
|
|
|
|
|
|
This release fixes a problem where element attributes were not separated by
|
|
|
|
spaces. Thanks to Jonathan Rochkind for reporting it and Bill Dueber providing
|
|
|
|
an initial patch for this problem.
|
|
|
|
|
2014-09-11 21:41:46 +00:00
|
|
|
## 0.1.0 - 2014-09-12
|
|
|
|
|
|
|
|
The first public release of Oga. This release contains support for parsing XML,
|
|
|
|
basic support for parsing HTML, support for querying documents using XPath and
|
|
|
|
more.
