# Changelog This document contains details of the various releases and their release dates. Dates are in the format `yyyy-mm-dd`. ## 0.1.3 - 2014-09-24 This release fixes a problem with serializing attributes using the namespace prefix "xmlns". See for more information. ## 0.1.2 - 2014-09-23 ### SAX API A SAX parser/API has been added. This API is useful when even the overhead of 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, '') handler.names # => ["foo", "bar"] ### Racc Gem Oga will now always use the Racc gem instead of the version shipped with the Ruby standard library. ### Error Reporting XML parser errors have been made a little bit more user friendly, though they can still be quite cryptic. ### Serializing Elements 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 (e.g. `` tags). Example: Oga.parse_xml('').to_xml # => "" Oga.parse_html('').to_xml # => "" ### Default Namespaces Namespaces are no longer removed from the attributes list when an element is created. Default XML namespaces can now be registered using `xmlns="..."`. Previously this would be ignored. Example: document = Oga.parse_xml('') root = document.children[0] root.namespace # => Namespace(name: "xmlns" uri: "baz") ### Lexing Incomplete Input Oga can now lex input such as ` Document(children: NodeSet(Text("') document.xpath('/') # => NodeSet(Document(children: NodeSet(Element(name: "root")))) ### Namespace Ordering Namespaces available to an element are now returned in the correct order. Previously outer namespaces would take precedence over inner namespaces, instead of it being the other way around. Example: document = Oga.parse_xml <<-EOF Text! EOF foo = document.at_xpath('root/container/foo:text') foo.namespace # => Namespace(name: "foo" uri: "baz") ### Parsing Capitalized HTML Void Elements Oga is now capable of parsing capitalized HTML void elements (e.g. `
`). Previously it could only parse lower-cased void elements. Thanks to Tero Tasanen for fixing this. Example: Oga.parse_html('
') # => Document(children: NodeSet(Element(name: "BR"))) ### Node Type Method Removed 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. ## 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.
