Hubbub binding for libdom
=========================
-Overview
---------
-
- This is an example binding of hubbub to libdom. It consists of two,
- orthogonal, parts:
-
- 1) hubbub parser wrapper
- 2) hubbub-specific DOMImplementationSource for libdom
-
-Push parser wrapper
--------------------
-
This is a wrapper around hubbub's parser API, to facilitate
construction of a libdom DOM tree. The basic premise is that the wrapper
intercepts the SAX-like events emitted by hubbub's tokeniser then builds
a libdom DOM tree from them.
-DOMImplementationSource
------------------------
-
- The DOMImplementationSource exposes the APIs needed to create a new
- document based upon the hubbub binding. It also provides the utility
- functions that libdom uses when performing some operations (such as
- document normalization). This is needed as libdom is document language
- agnostic; therefore, it requires support from the binding to perform
- some operations.

LibXML binding for libdom
=========================
-Overview
---------
-
- This is an example binding of libxml2 to libdom. It consists of two,
- orthogonal, parts:
-
- 1) libxml push parser wrapper
- 2) libxml-specific DOMImplementationSource for libdom
-
-Push parser wrapper
--------------------
-
This is a wrapper around libxml's push parser API, to facilitate
construction of a libdom DOM tree. The basic premise is that the wrapper
intercepts the SAX events emitted by libxml's tokeniser then invokes

DOM tree using libxml api, should it need to (e.g. for normalization
purposes).
-DOMImplementationSource
------------------------
-
- The DOMImplementationSource exposes the APIs needed to create a new
- document based upon the libxml binding. It also provides the utility
- functions that libdom uses when performing some operations (such as
- document normalization). This is needed as libdom is document language
- agnostic; therefore, it requires support from the binding to perform
- some operations.

For example, implementations should raise an implementation-dependent exception if a<code>null</code>argument is passed.</p><p>Some languages and object systems do not support the concept of exceptions. For such systems, error conditions may be indicated using native error reporting mechanisms. For some bindings, for example, methods may return error codes similar to those listed in the corresponding method descriptions.</p></descr><component id="ID-146F692A" name="code"><typename>unsigned short</typename></component></exception>

+ <interface name="DocumentFragment" inherits="Node" id="ID-B63ED1A3"><descr><p><code>DocumentFragment</code>is a "lightweight" or "minimal"<code>Document</code>object. It is very common to want to be able to extract a portion of a document's tree or to create a new fragment of a document. Imagine implementing a user command like cut or rearranging a document by moving fragments around. It is desirable to have an object which can hold such fragments and it is quite natural to use a Node for this purpose. While it is true that a<code>Document</code>object could fulfill this role, a<code>Document</code>object can potentially be a heavyweight object, depending on the underlying implementation. What is really needed for this is a very lightweight object.<code>DocumentFragment</code>is such an object.</p><p>Furthermore, various operations -- such as inserting nodes as children of another<code>Node</code>-- may take<code>DocumentFragment</code>objects as arguments; this results in all the child nodes of the<code>DocumentFragment</code>being moved to the child list of this node.</p><p>The children of a<code>DocumentFragment</code>node are zero or more nodes representing the tops of any sub-trees defining the structure of the document.<code>DocumentFragment</code>nodes do not need to be<termref def="dt-well-formed">well-formed XML documents</termref>(although they do need to follow the rules imposed upon well-formed XML parsed entities, which can have multiple top nodes). For example, a<code>DocumentFragment</code>might have only one child and that child node could be a<code>Text</code>node. Such a structure model represents neither an HTML document nor a well-formed XML document.</p><p>When a<code>DocumentFragment</code>is inserted into a<code>Document</code>(or indeed any other<code>Node</code>that may take children) the children of the<code>DocumentFragment</code>and not the<code>DocumentFragment</code>itself are inserted into the<code>Node</code>. This makes the<code>DocumentFragment</code>very useful when the user wishes to create nodes that are<termref def="dt-sibling">siblings</termref>; the<code>DocumentFragment</code>acts as the parent of these nodes so that the user can use the standard methods from the<code>Node</code>interface, such as<code>insertBefore</code>and<code>appendChild</code>.</p></descr></interface>
+ <interface name="Document" inherits="Node" id="i-Document"><descr><p>The<code>Document</code>interface represents the entire HTML or XML document. Conceptually, it is the<termref def="dt-root-node">root</termref>of the document tree, and provides the primary access to the document's data.</p><p>Since elements, text nodes, comments, processing instructions, etc. cannot exist outside the context of a<code>Document</code>, the<code>Document</code>interface also contains the factory methods needed to create these objects. The<code>Node</code>objects created have a<code>ownerDocument</code>attribute which associates them with the<code>Document</code>within whose context they were created.</p></descr><attribute readonly="yes" name="doctype" type="DocumentType" id="ID-B63ED1A31"><descr><p>The Document Type Declaration (see<code>DocumentType</code>) associated with this document. For HTML documents as well as XML documents without a document type declaration this returns<code>null</code>.

Typically the allowable values for the attribute are defined in a document type definition.</p><p><code>Attr</code>objects inherit the<code>Node</code>interface, but since they are not actually child nodes of the element they describe, the DOM does not consider them part of the document tree. Thus, the<code>Node</code>attributes<code>parentNode</code>,<code>previousSibling</code>, and<code>nextSibling</code>have a<code>null</code>value for<code>Attr</code>objects. The DOM takes the view that attributes are properties of elements rather than having a separate identity from the elements they are associated with; this should make it more efficient to implement such features as default attributes associated with all elements of a given type. Furthermore,<code>Attr</code>nodes may not be immediate children of a<code>DocumentFragment</code>. However, they can be associated with<code>Element</code>nodes contained within a<code>DocumentFragment</code>.

+ <interface name="CDATASection" inherits="Text" id="ID-667469212"><descr><p>CDATA sections are used to escape blocks of text containing characters that would otherwise be regarded as markup. The only delimiter that is recognized in a CDATA section is the "]]&gt;" string that ends the CDATA section. CDATA sections cannot be nested. Their primary purpose is for including material such as XML fragments, without needing to escape all the delimiters.</p><p>The<code>DOMString</code>attribute of the<code>Text</code>node holds the text that is contained by the CDATA section. Note that this<emph>may</emph>contain characters that need to be escaped outside of CDATA sections and that, depending on the character encoding ("charset") chosen for serialization, it may be impossible to write out some characters as part of a CDATA section.</p><p>The<code>CDATASection</code>interface inherits from the<code>CharacterData</code>interface through the<code>Text</code>interface. Adjacent<code>CDATASection</code>nodes are not merged by use of the<code>normalize</code>method of the<code>Node</code>interface.</p><note><p>Because no markup is recognized within a<code>CDATASection</code>, character numeric references cannot be used as an escape mechanism when serializing. Therefore, action needs to be taken when serializing a<code>CDATASection</code>with a character encoding where some of the contained characters cannot be represented. Failure to do so would not produce well-formed XML.</p><p>One potential solution in the serialization process is to end the CDATA section before the character, output the character using a character reference or entity reference, and open a new CDATA section for any further characters in the text node. Note, however, that some code conversion libraries at the time of writing do not return an error or exception when a character is missing from the encoding, making the task of ensuring that data is not corrupted on serialization more difficult.</p></note></descr></interface>
