This is a shortcut for "!foo". Using this method one doesn't have to
worry about how the "!" operator binds. For example, this:
!foo.or(bar)
would be parsed/evaluated as this:
!(foo.or(bar))
when instead we want it to be this:
(!foo).or(bar)
Using explicit parenthesis leads to ugly code, so now we can do this
instead:
foo.not.or(bar)
This also comes with some changes to the specs as the old behaviour of
the Evaluator was incorrect. The Evaluator would bail after matching a
single node but instead it's meant to continue until it runs out of
parent nodes.
Prevents a superfluous end tag of a self-closing HTML tag from
closing its parent element prematurely, for example:
```html
<object><param></param><param></param></object>
```
(note <param> is self closing) being turned into:
```html
<object><param/></object><param/>
```
This is a Nokogiri extension (as far as I'm aware) but it's useful
enough to also include in Oga. Selectors such as "foo:nth(2)" are simply
compiled to XPath "descendant::foo[position() = 2]".
Fixes#123
This allows for parsing of HTML such as:
<a href=lol("javascript")></a>
Here the "href" attribute would have its value set to:
lol("javascript")
Fixes#119
```
element = Oga::XML::Element.new(:name => 'div')
some_node.replace(element)
```
You can also pass a `String` to `replace` and it will be replaced with
a `Oga::XML::Text` node
```
some_node.replace('this will replace the current node with a text node')
```
closes#115
Currently this only disabled the automatic insertion of closing tags, in
the future this may also disable other features if deemed worth the
effort.
Fixes#107
This allows the lexer to process input such as:
<a href=foo"></a>
For XML input the lexer still expects properly opened/closed attribute
values.
Fixes#109
This ensures that entities such as "½" are decoded properly.
Previously this would be ignored as the regular expression used for this
only matched [a-zA-Z].
This was adapted from PR #111.
Previous HTML such as this would be lexed incorrectly:
<div>
<ul>
<li>foo
</ul>
inside div
</div>
outside div
The lexer would see this as the following instead:
<div>
<ul>
<li>foo</li>
inside div
</ul>
outside div
</div>
This commit exposes the name of the closing tag to
XML::Lexer#on_element_end (omitted for self closing tags). This can be
used to automatically close nested tags that were left open, ensuring
the above HTML is lexer correctly.
The new setup ignores namespace prefixes as these are not used in HTML,
XML in turn won't even run the code to begin with since it doesn't allow
one to leave out closing tags.
