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(). + + \l 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. + \snippet doc/src/snippets/code/src_xml_dom_qdom.cpp 1 + + For further information about the Document Object Model see + \l{http://www.w3.org/TR/REC-DOM-Level-1/}{Level 1} and + \l{http://www.w3.org/TR/DOM-Level-2-Core/}{Level 2 Core}. + For a more general introduction of the DOM implementation see the + QDomDocument documentation. +*/ + +/*! + Constructs a \link isNull() null\endlink node. +*/ +QDomNode::QDomNode() +{ + impl = 0; +} + +/*! + Constructs a copy of \a n. + + The data of the copy is shared (shallow copy): modifying one node + will also change the other.

The node objects created have an ownerDocument() function + which associates them with the document within whose context they + were created. The DOM classes that will be used most often are + QDomNode, QDomDocument, QDomElement and QDomText. + + The parsed XML is represented internally by a tree of objects that + can be accessed using the various QDom classes. All QDom classes + only \e reference objects in the internal tree. The internal + objects in the DOM tree will get deleted once the last QDom + object referencing them and the QDomDocument itself are deleted. + + Creation of elements, text nodes, etc. is done using the various + factory functions provided in this class. Using the default + constructors of the QDom classes will only result in empty + objects that cannot be manipulated or inserted into the Document. + + The QDomDocument class has several functions for creating document + data, for example, createElement(), createTextNode(), + createComment(), createCDATASection(), + createProcessingInstruction(), createAttribute() and + createEntityReference(). Some of these functions have versions + that support namespaces, i.e. createElementNS() and + createAttributeNS(). The createDocumentFragment() function is used + to hold parts of the document; this is useful for manipulating for + complex documents. + + The entire content of the document is set with setContent(). This + function parses the string it is passed as an XML document and + creates the DOM tree that represents the document. The root + element is available using documentElement().
