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();
    }

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.

See also:
insertAfter(), replaceChild(), removeChild(), and appendChild().

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.

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.

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.

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.
