    public class QDomNode

extends QtJambiObject
implements java.lang.Cloneable

The `QDomNode` class is the base class for all the nodes in a DOM tree. Many functions in the DOM return a `QDomNode`.

You can find out the type of a node using `isAttr()`, `isCDATASection()`, `isDocumentFragment()`, `isDocument()`, `isDocumentType()`, `isElement()`, `isEntityReference()`, `isText()`, `isEntity()`, `isNotation()`, `isProcessingInstruction()`, `isCharacterData()` and `isComment()`.

A `QDomNode` can be converted into one of its subclasses using `toAttr()`, `toCDATASection()`, `toDocumentFragment()`, `toDocument()`, `toDocumentType()`, `toElement()`, `toEntityReference()`, `toText()`, `toEntity()`, `toNotation()`, `toProcessingInstruction()`, `toCharacterData()` or `toComment()`. You can convert a node to a null node with `clear()`.

Copies of the `QDomNode` class share their data using explicit sharing. This means that modifying one node will change all copies. This is especially useful in combination with functions which return a `QDomNode`, e.g. `firstChild()`. You can make an independent (deep) copy of the node with `cloneNode()`.

A `QDomNode` can be null, much like a null pointer. Creating a copy of a null node results in another null node. It is not possible to modify a null node, but it is possible to assign another, possibly non-null node to it. In this case, the copy of the null node will remain null. You can check if a `QDomNode` is null by calling `isNull()`. The empty constructor of a `QDomNode` (or any of the derived classes) creates a null node.

Nodes are inserted with `insertBefore()`, `insertAfter()` or `appendChild()`. You can replace one node with another using `replaceChild()` and remove a node with `removeChild()`.

To traverse nodes use `firstChild()` to get a node's first child (if any), and `nextSibling()` to traverse. `QDomNode` also provides `lastChild()`, `previousSibling()` and `parentNode()`. To find the first child node with a particular node name use `namedItem()`.

To find out if a node has children use `hasChildNodes()` and to get a list of all of a node's children use `childNodes()`.

The node's name and value (the meaning of which varies depending on its type) is returned by `nodeName()` and `nodeValue()` respectively. The node's type is returned by `nodeType()`. The node's value can be set with `setNodeValue()`.

The document to which the node belongs is returned by `ownerDocument()`.

Adjacent `QDomText` nodes can be merged into a single node with `normalize()`.

`QDomElement` nodes have attributes which can be retrieved with attributes().

`QDomElement` and `QDomAttr` nodes can have namespaces which can be retrieved with `namespaceURI()`. Their local name is retrieved with `localName()`, and their prefix with `prefix()`. The prefix can be set with `setPrefix()`.

You can write the XML representation of the node to a text stream with `save()`.

The following example looks for the first element in an XML document and prints the names of all the elements that are its direct children.

        QDomDocument d = new QDomDocument();
        d.setContent(someXML);
        QDomNode n = d.firstChild();
        while (!n.isNull()) {
            if (n.isElement()) {
                QDomElement e = n.toElement();
                System.out.printf("Element name: %s\n", e.tagName());
                break;
            }
            n = n.nextSibling();
        }

For further information about the Document Object Model see Level 1 and Level 2 Core. For a more general introduction of the DOM implementation see the `QDomDocument` documentation.

Constructor Detail

### QDomNode

    public QDomNode()

  Constructs a `null` node.

### QDomNode

    public QDomNode(QDomNode arg__1)

  Constructs a copy of `n`.

  The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use `cloneNode()`.

Method Detail

### appendChild

    public final QDomNode appendChild(QDomNode newChild)

  Appends `newChild` as the node's last child.

  If `newChild` is the child of another node, it is reparented to this node. If `newChild` is a child of this node, then its position in the list of children is changed.

  If `newChild` is a `QDomDocumentFragment`, then the children of the fragment are removed from the fragment and appended.

  If `newChild` is a `QDomElement` and this node is a `QDomDocument` that already has an element node as a child, `newChild` is not added as a child and a null node is returned.

  Calling this function on a null node(created, for example, with the default constructor) does nothing.

  The DOM specification disallow inserting attribute nodes, but due to historical reasons `QDom` accept them nevertheless.

See also:
  `insertBefore()`, `insertAfter()`, `replaceChild()`, and `removeChild()`.

### childNodes

    public final QDomNodeList childNodes()

  Returns a list of all direct child nodes.

  Most often you will call this function on a `QDomElement` object.

  For example, if the XML document looks like this:

          <body>
          <h1>Heading</h1>
          <p>Hello <b>you</b></p>
          </body>

  Then the list of child nodes for the "body"-element will contain the node created by the <h1> tag and the node created by the <p> tag.

  The nodes in the list are not copied; so changing the nodes in the list will also change the children of this node.

See also:
  `firstChild()`, and `lastChild()`.

### clear

    public final void clear()

  Converts the node into a null node; if it was not a null node before, its type and contents are deleted.

See also:
  `isNull()`.

### cloneNode

    public final QDomNode cloneNode()

  Creates a deep (not shallow) copy of the `QDomNode`.

  If `deep` is true, then the cloning is done recursively which means that all the node's children are deep copied too. If `deep` is false only the node itself is copied and the copy will have no child nodes.

### cloneNode

    public final QDomNode cloneNode(boolean deep)

  Creates a deep (not shallow) copy of the `QDomNode`.

  If `deep` is true, then the cloning is done recursively which means that all the node's children are deep copied too. If `deep` is false only the node itself is copied and the copy will have no child nodes.

### columnNumber

    public final int columnNumber()

  For nodes created by `QDomDocument::setContent()`, this function returns the column number in the XML document where the node was parsed. Otherwise, -1 is returned.

See also:
  `lineNumber()`, and `QDomDocument::setContent()`.

### firstChild

    public final QDomNode firstChild()

  Returns the first child of the node. If there is no child node, a `null node` is returned. Changing the returned node will also change the node in the document tree.

See also:
  `lastChild()`, and `childNodes()`.

### firstChildElement

    public final QDomElement firstChildElement()

  Returns the first child element with tag name `tagName` if `tagName` is non-empty; otherwise returns the first child element. Returns a null element if no such child exists.

See also:
  `lastChildElement()`, `previousSiblingElement()`, and `nextSiblingElement()`.

### firstChildElement

    public final QDomElement firstChildElement(java.lang.String tagName)

  Returns the first child element with tag name `tagName` if `tagName` is non-empty; otherwise returns the first child element. Returns a null element if no such child exists.

See also:
  `lastChildElement()`, `previousSiblingElement()`, and `nextSiblingElement()`.

### hasAttributes

    public final boolean hasAttributes()

  Returns true if the node has attributes; otherwise returns false.

See also:
  attributes().

### hasChildNodes

    public final boolean hasChildNodes()

  Returns true if the node has one or more children; otherwise returns false.

### insertAfter

    public final QDomNode insertAfter(QDomNode newChild,
                                      QDomNode refChild)

  Inserts the node `newChild` after the child node `refChild`. `refChild` must be a direct child of this node. If `refChild` is `null` then `newChild` is appended as this node's last child.

  If `newChild` is the child of another node, it is reparented to this node. If `newChild` is a child of this node, then its position in the list of children is changed.

  If `newChild` is a `QDomDocumentFragment`, then the children of the fragment are removed from the fragment and inserted after `refChild`.

  Returns a new reference to `newChild` on success or a `null node` on failure.

  The DOM specification disallow inserting attribute nodes, but due to historical reasons `QDom` accept them nevertheless.

See also:
  `insertBefore()`, `replaceChild()`, `removeChild()`, and `appendChild()`.

### insertBefore

    public final QDomNode insertBefore(QDomNode newChild,
                                       QDomNode refChild)

  Inserts the node `newChild` before the child node `refChild`. `refChild` must be a direct child of this node. If `refChild` is `null` then `newChild` is inserted as the node's first child.

  If `newChild` is the child of another node, it is reparented to this node. If `newChild` is a child of this node, then its position in the list of children is changed.

  If `newChild` is a `QDomDocumentFragment`, then the children of the fragment are removed from the fragment and inserted before `refChild`.

  Returns a new reference to `newChild` on success or a `null node` on failure.

  The DOM specification disallow inserting attribute nodes, but due to historical reasons `QDom` accept them nevertheless.

### nodeName

    public final java.lang.String nodeName()

  Returns the name of the node.

  The meaning of the name depends on the subclass:

  `QDomProcessingInstruction` | The target of the processing instruction
  `QDomText` | The string "#text"

  Note: This function does not take the presence of namespaces into account when processing the names of element and attribute nodes. As a result, the returned name can contain any namespace prefix that may be present. To obtain the node name of an element or attribute, use `localName()`; to obtain the namespace prefix, use `namespaceURI()`.

See also:
  `nodeValue()`.

### nodeType

    public final QDomNode.NodeType nodeType()

  Returns the type of the node.

See also:
  `toAttr()`, `toCDATASection()`, `toDocumentFragment()`, `toDocument()`, `toDocumentType()`, `toElement()`, `toEntityReference()`, `toText()`, `toEntity()`, `toNotation()`, `toProcessingInstruction()`, `toCharacterData()`, and `toComment()`.

### nodeValue

    public final java.lang.String nodeValue()

  Returns the value of the node.

  The meaning of the value depends on the subclass:

  Name | Meaning
  --- | ---
  `QDomAttr` | The attribute value
  `QDomCDATASection` | The content of the CDATA section
  `QDomComment` | The comment
  `QDomProcessingInstruction` | The data of the processing instruction
  `QDomText` | The text

  All the other subclasses do not have a node value and will return an empty string.

See also:
  `setNodeValue()`, and `nodeName()`.

### normalize

    public final void normalize()

  Calling `normalize()` on an element converts all its children into a standard form. This means that adjacent `QDomText` objects will be merged into a single text object (`QDomCDATASection` nodes are not merged).

### writeTo

    public final void writeTo(QTextStream arg__1)

  Writes thisQDomNode

### ownerDocument

    public final QDomDocument ownerDocument()

  Returns the document to which this node belongs.

### parentNode

    public final QDomNode parentNode()

  Returns the parent node. If this node has no parent, a null node is returned (i.e. a node for which `isNull()` returns true).

### prefix

    public final java.lang.String prefix()

  Returns the namespace prefix of the node or an empty string if the node has no namespace prefix.

  Only nodes of type `ElementNode` or `AttributeNode` can have namespaces. A namespace prefix must be specified at creation time. If a node was created with a namespace prefix, you can change it later with `setPrefix()`.

  If you create an element or attribute with `QDomDocument::createElement()` or `QDomDocument::createAttribute()`, the prefix will be an empty string. If you use `QDomDocument::createElementNS()` or `QDomDocument::createAttributeNS()` instead, the prefix will not be an empty string; but it might be an empty string if the name does not have a prefix.

  `QDomDocument::createElementNS()``QDomDocument::createAttributeNS()`

See also:
  `setPrefix()`, `localName()`, and `namespaceURI()`.

### previousSibling

    public final QDomNode previousSibling()

  Returns the previous sibling in the document tree. Changing the returned node will also change the node in the document tree.

  For example, if you have XML like this:

          <h1>Heading</h1>
          <p>The text...</p>
          <h2>Next heading</h2>

  and this `QDomNode` represents the <p> tag, `previousSibling()` will return the node representing the <h1> tag.

See also:
  `nextSibling()`.

### previousSiblingElement

    public final QDomElement previousSiblingElement()

  Returns the previous sibilng element with tag name `tagName` if `tagName` is non-empty; otherwise returns any previous sibling element. Returns a null element if no such sibling exists.

See also:
  `firstChildElement()`, `nextSiblingElement()`, and `lastChildElement()`.

### previousSiblingElement

    public final QDomElement previousSiblingElement(java.lang.String tagName)

  Returns the previous sibilng element with tag name `tagName` if `tagName` is non-empty; otherwise returns any previous sibling element. Returns a null element if no such sibling exists.

See also:
  `firstChildElement()`, `nextSiblingElement()`, and `lastChildElement()`.

### removeChild

    public final QDomNode removeChild(QDomNode oldChild)

  Removes `oldChild` from the list of children. `oldChild` must be a direct child of this node.

  Returns a new reference to `oldChild` on success or a `null node` on failure.

See also:
  `insertBefore()`, `insertAfter()`, `replaceChild()`, and `appendChild()`.

### replaceChild

    public final QDomNode replaceChild(QDomNode newChild,
                                       QDomNode oldChild)

  Replaces `oldChild` with `newChild`. `oldChild` must be a direct child of this node.

  If `newChild` is the child of another node, it is reparented to this node. If `newChild` is a child of this node, then its position in the list of children is changed.

  If `newChild` is a `QDomDocumentFragment`, then `oldChild` is replaced by all of the children of the fragment.

  Returns a new reference to `oldChild` on success or a `null node` an failure.

See also:
  `insertBefore()`, `insertAfter()`, `removeChild()`, and `appendChild()`.

### save

    public final void save(QTextStream arg__1,
                           int arg__2)

  Writes the XML representation of the node and all its children to the stream `str`. This function uses `indent` as the amount of space to indent the node.

  If this node is a document node, the encoding of text stream `str`'s encoding is set by treating a processing instruction by name "xml" as an XML declaration, if such a one exists, and otherwise defaults to UTF-8. XML declarations are not processing instructions, but this behavior exists for historical reasons. If this node is not a document node, the text stream's encoding is used.

  If the document contains invalid XML characters or characters that cannot be encoded in the given encoding, the result and behavior is undefined.

### save

    public final void save(QTextStream arg__1,
                           int arg__2,
                           QDomNode.EncodingPolicy arg__3)

  If `encodingPolicy` is `QDomNode::EncodingFromDocument` , this function behaves as save(`QTextStream` &str, int indent).

  If `encodingPolicy` is `EncodingFromTextStream` and this node is a document node, this function behaves as save(`QTextStream` &str, int indent) with the exception that the encoding specified in the text stream `str` is used.

  If the document contains invalid XML characters or characters that cannot be encoded in the given encoding, the result and behavior is undefined.

### setNodeValue

    public final void setNodeValue(java.lang.String arg__1)

  Sets the node's value to `v`.

See also:
  `nodeValue()`.

### setPrefix

    public final void setPrefix(java.lang.String pre)

  If the node has a namespace prefix, this function changes the namespace prefix of the node to `pre`. Otherwise this function does nothing.

  Only nodes of type `ElementNode` or `AttributeNode` can have namespaces. A namespace prefix must have be specified at creation time; it is not possible to add a namespace prefix afterwards.

  `QDomDocument::createElementNS()``QDomDocument::createAttributeNS()`

See also:
  `prefix()`, `localName()`, and `namespaceURI()`.
