|
---|
| 72 | * OMDocumentFragment is a "lightweight" or "minimal"
|
---|
| 73 | * DOMDocument object.
|
---|
| 74 | *
|
---|
| 75 | * It is very common to want to be able to
|
---|
| 76 | * extract a portion of a document's tree or to create a new fragment of a
|
---|
| 77 | * document. Imagine implementing a user command like cut or rearranging a
|
---|
| 78 | * document by moving fragments around. It is desirable to have an object
|
---|
| 79 | * which can hold such fragments and it is quite natural to use a DOMNode for
|
---|
| 80 | * this purpose. While it is true that a <code>DOMDocument</code> object could
|
---|
| 81 | * fulfil this role, a <code>DOMDocument</code> object can potentially be a
|
---|
| 82 | * heavyweight object, depending on the underlying implementation. What is
|
---|
| 83 | * really needed for this is a very lightweight object.
|
---|
| 84 | * <code>DOMDocumentFragment</code> is such an object.
|
---|
| 85 | * <p>Furthermore, various operations -- such as inserting nodes as children
|
---|
| 86 | * of another <code>DOMNode</code> -- may take <code>DOMDocumentFragment</code>
|
---|
| 87 | * objects as arguments; this results in all the child nodes of the
|
---|
| 88 | * <code>DOMDocumentFragment</code> being moved to the child list of this node.
|
---|
| 89 | * <p>The children of a <code>DOMDocumentFragment</code> node are zero or more
|
---|
| 90 | * nodes representing the tops of any sub-trees defining the structure of the
|
---|
| 91 | * document. <code>DOMDocumentFragment</code> nodes do not need to be
|
---|
| 92 | * well-formed XML documents (although they do need to follow the rules
|
---|
| 93 | * imposed upon well-formed XML parsed entities, which can have multiple top
|
---|
| 94 | * nodes). For example, a <code>DOMDocumentFragment</code> might have only one
|
---|
| 95 | * child and that child node could be a <code>DOMText</code> node. Such a
|
---|
| 96 | * structure model represents neither an HTML document nor a well-formed XML
|
---|
| 97 | * document.
|
---|
| 98 | * <p>When a <code>DOMDocumentFragment</code> is inserted into a
|
---|
| 99 | * <code>DOMDocument</code> (or indeed any other <code>DOMNode</code> that may take
|
---|
| 100 | * children) the children of the <code>DOMDocumentFragment</code> and not the
|
---|
| 101 | * <code>DOMDocumentFragment</code> itself are inserted into the
|
---|
| 102 | * <code>DOMNode</code>. This makes the <code>DOMDocumentFragment</code> very
|
---|
| 103 | * useful when the user wishes to create nodes that are siblings; the
|
---|
| 104 | * <code>DOMDocumentFragment</code> acts as the parent of these nodes so that the
|
---|
| 105 | * user can use the standard methods from the <code>DOMNode</code> interface,
|
---|
| 106 | * such as <code>insertBefore()</code> and <code>appendChild()</code>.
|
---|
| 107 | *
|
---|
| 108 | * @since DOM Level 1
