.SH DESCRIPTION
The TQDomNode class is the base class for all the nodes in a DOM tree.
.PP
Many functions in the DOM return a TQDomNode.
.PP
You can find out the type of a node using isAttr(), isCDATASection(), isDocumentFragment(), isDocument(), isDocumentType(), isElement(), isEntityReference(), isText(), isEntity(), isNotation(), isProcessingInstruction(), isCharacterData() and isComment().
.PP
A TQDomNode 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().
.PP
Copies of the TQDomNode 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 TQDomNode, e.g. firstChild(). You can make an independent (deep) copy of the node with cloneNode().
.PP
Nodes are inserted with insertBefore(), insertAfter() or appendChild(). You can replace one node with another using replaceChild() and remove a node with removeChild().
.PP
To traverse nodes use firstChild() to get a node's first child (if any), and nextSibling() to traverse. TQDomNode also provides lastChild(), previousSibling() and parentNode(). To find the first child node with a particular node name use namedItem().
.PP
To find out if a node has children use hasChildNodes() and to get a list of all of a node's children use childNodes().
.PP
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().
.PP
The document to which the node belongs is returned by ownerDocument().
.PP
Adjacent TQDomText nodes can be merged into a single node with normalize().
.PP
TQDomElement nodes have attributes which can be retrieved with attributes().
.PP
TQDomElement and TQDomAttr 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().
.PP
You can write the XML representation of the node to a text stream with save().
.PP
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.
.PP
.nf
.br
TQDomDocument d;
.br
d.setContent( someXML );
.br
TQDomNode n = d.firstChild();
.br
while ( !n.isNull() ) {
.br
if ( n.isElement() ) {
.br
TQDomElement e = n.toElement();
.br
cout << "Element name: " << e.tagName() << endl;
.br
break;
.br
}
.br
n = n.nextSibling();
.br
}
.br
.fi

.SH MEMBER FUNCTION DOCUMENTATION
.SH "TQDomNode::TQDomNode ()"
Constructs a null node.
.SH "TQDomNode::TQDomNode ( const TQDomNode & n )"
Constructs a copy of \fIn\fR.
.PP
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().
.SH "TQDomNode::~TQDomNode ()\fC [virtual]\fR"
Destroys the object and frees its resources.
.SH "TQDomNode TQDomNode::appendChild ( const TQDomNode & newChild )\fC [virtual]\fR"
Appends \fInewChild\fR as the node's last child.
.PP
If \fInewChild\fR is the child of another node, it is reparented to this node. If \fInewChild\fR is a child of this node, then its position in the list of children is changed.
.PP
If \fInewChild\fR is a TQDomDocumentFragment, then the children of the fragment are removed from the fragment and appended.
.PP
Returns a new reference to \fInewChild\fR.
.PP
See also insertBefore(), insertAfter(), replaceChild(), and removeChild().
.SH "TQDomNamedNodeMap TQDomNode::attributes () const\fC [virtual]\fR"
Returns a named node map of all attributes. Attributes are only provided for TQDomElements.
.PP
Changing the attributes in the map will also change the attributes of this TQDomNode.
.PP
Reimplemented in TQDomElement.
.SH "TQDomNodeList TQDomNode::childNodes () const\fC [virtual]\fR"
Returns a list of all direct child nodes.
.PP
Most often you will call this function on a TQDomElement object.
.PP
For example, if the XML document looks like this:
.PP
.nf
.br
<body>
.br
<h1>Heading</h1>
.br
<p>Hello <b>you</b></p>
.br
</body>
.br
.fi
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.
.PP
The nodes in the list are not copied; so changing the nodes in the list will also change the children of this node.
.PP
See also firstChild() and lastChild().
.SH "void TQDomNode::clear ()"
Converts the node into a null node; if it was not a null node before, its type and contents are deleted.
.PP
See also isNull().
.SH "TQDomNode TQDomNode::cloneNode ( bool deep = TRUE ) const\fC [virtual]\fR"
Creates a deep (not shallow) copy of the TQDomNode.
.PP
If \fIdeep\fR is TRUE, then the cloning is done recursively which means that all the node's children are deep copied too. If \fIdeep\fR is FALSE only the node itself is copied and the copy will have no child nodes.
.SH "TQDomNode TQDomNode::firstChild () const\fC [virtual]\fR"
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.
.PP
See also lastChild() and childNodes().
.PP
Example: xml/outliner/outlinetree.cpp.
.SH "bool TQDomNode::hasAttributes () const\fC [virtual]\fR"
Returns TRUE if the node has attributes; otherwise returns FALSE.
.PP
See also attributes().
.SH "bool TQDomNode::hasChildNodes () const\fC [virtual]\fR"
Returns TRUE if the node has one or more children; otherwise returns FALSE.
.SH "TQDomNode TQDomNode::insertAfter ( const TQDomNode & newChild, const TQDomNode & refChild )\fC [virtual]\fR"
Inserts the node \fInewChild\fR after the child node \fIrefChild\fR. \fIrefChild\fR must be a direct child of this node. If \fIrefChild\fR is null then \fInewChild\fR is appended as this node's last child.
.PP
If \fInewChild\fR is the child of another node, it is reparented to this node. If \fInewChild\fR is a child of this node, then its position in the list of children is changed.
.PP
If \fInewChild\fR is a TQDomDocumentFragment, then the children of the fragment are removed from the fragment and inserted after \fIrefChild\fR.
.PP
Returns a new reference to \fInewChild\fR on success or a null node on failure.
.PP
See also insertBefore(), replaceChild(), removeChild(), and appendChild().
.SH "TQDomNode TQDomNode::insertBefore ( const TQDomNode & newChild, const TQDomNode & refChild )\fC [virtual]\fR"
Inserts the node \fInewChild\fR before the child node \fIrefChild\fR. \fIrefChild\fR must be a direct child of this node. If \fIrefChild\fR is null then \fInewChild\fR is inserted as the node's first child.
.PP
If \fInewChild\fR is the child of another node, it is reparented to this node. If \fInewChild\fR is a child of this node, then its position in the list of children is changed.
.PP
If \fInewChild\fR is a TQDomDocumentFragment, then the children of the fragment are removed from the fragment and inserted before \fIrefChild\fR.
.PP
Returns a new reference to \fInewChild\fR on success or a null node on failure.
.PP
See also insertAfter(), replaceChild(), removeChild(), and appendChild().

.PP
See also setNodeValue() and nodeName().
.PP
Example: xml/outliner/outlinetree.cpp.
.SH "void TQDomNode::normalize ()\fC [virtual]\fR"
Calling normalize() on an element converts all its children into a standard form. This means that adjacent TQDomText objects will be merged into a single text object (TQDomCDATASection nodes are not merged).
.SH "bool TQDomNode::operator!= ( const TQDomNode & n ) const"
Returns TRUE if \fIn\fR and this DOM node are not equal; otherwise returns FALSE.
.SH "TQDomNode & TQDomNode::operator= ( const TQDomNode & n )"
Assigns a copy of \fIn\fR to this DOM node.
.PP
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().
.SH "bool TQDomNode::operator== ( const TQDomNode & n ) const"
Returns TRUE if \fIn\fR and this DOM node are equal; otherwise returns FALSE.
.SH "TQDomDocument TQDomNode::ownerDocument () const\fC [virtual]\fR"
Returns the document to which this node belongs.
.SH "TQDomNode TQDomNode::parentNode () const\fC [virtual]\fR"
Returns the parent node. If this node has no parent, a null node is returned (i.e. a node for which isNull() returns TRUE).
.SH "TQString TQDomNode::prefix () const\fC [virtual]\fR"
Returns the namespace prefix of the node or TQString::null if the node has no namespace prefix.
.PP
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().
.PP
If you create an element or attribute with TQDomDocument::createElement() or TQDomDocument::createAttribute(), the prefix will be TQString::null. If you use TQDomDocument::createElementNS() or TQDomDocument::createAttributeNS() instead, the prefix will not be TQString::null; but it might be an empty string if the name does not have a prefix.
.PP
See also setPrefix(), localName(), namespaceURI(), TQDomDocument::createElementNS(), and TQDomDocument::createAttributeNS().
.SH "TQDomNode TQDomNode::previousSibling () const\fC [virtual]\fR"
Returns the previous sibling in the document tree. Changing the returned node will also change the node in the document tree.
.PP
For example, if you have XML like this:
.PP
.nf
.br
<h1>Heading</h1>
.br
<p>The text...</p>
.br
<h2>Next heading</h2>
.br
.fi
and this TQDomNode represents the <p> tag, previousSibling() will return the node representing the <h1> tag.
.PP
See also nextSibling().
.SH "TQDomNode TQDomNode::removeChild ( const TQDomNode & oldChild )\fC [virtual]\fR"
Removes \fIoldChild\fR from the list of children. \fIoldChild\fR must be a direct child of this node.
.PP
Returns a new reference to \fIoldChild\fR on success or a null node on failure.
.PP
See also insertBefore(), insertAfter(), replaceChild(), and appendChild().
.SH "TQDomNode TQDomNode::replaceChild ( const TQDomNode & newChild, const TQDomNode & oldChild )\fC [virtual]\fR"
Replaces \fIoldChild\fR with \fInewChild\fR. \fIoldChild\fR must be a direct child of this node.
.PP
If \fInewChild\fR is the child of another node, it is reparented to this node. If \fInewChild\fR is a child of this node, then its position in the list of children is changed.
.PP
If \fInewChild\fR is a TQDomDocumentFragment, then \fIoldChild\fR is replaced by all of the children of the fragment.
.PP
Returns a new reference to \fIoldChild\fR on success or a null node an failure.
.PP
See also insertBefore(), insertAfter(), removeChild(), and appendChild().
.SH "void TQDomNode::save ( TQTextStream & str, int indent ) const"
Writes the XML representation of the node and all its children to the stream \fIstr\fR. This function uses \fIindent\fR as the amount of space to indent the node.
.SH "void TQDomNode::setNodeValue ( const TQString & v )\fC [virtual]\fR"
Sets the node's value to \fIv\fR.
.PP
See also nodeValue().
.SH "void TQDomNode::setPrefix ( const TQString & pre )\fC [virtual]\fR"
If the node has a namespace prefix, this function changes the namespace prefix of the node to \fIpre\fR. Otherwise this function does nothing.
.PP
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.
.PP
See also prefix(), localName(), namespaceURI(), TQDomDocument::createElementNS(), and TQDomDocument::createAttributeNS().
.SH "TQDomAttr TQDomNode::toAttr ()"

.PP
See also isAttr().
.SH "TQDomCDATASection TQDomNode::toCDATASection ()"
Converts a TQDomNode into a TQDomCDATASection. If the node is not a CDATA section, the returned object will be null.
.PP
See also isCDATASection().
.SH "TQDomCharacterData TQDomNode::toCharacterData ()"
Converts a TQDomNode into a TQDomCharacterData. If the node is not a character data node the returned object will be null.
.PP
See also isCharacterData().
.SH "TQDomComment TQDomNode::toComment ()"
Converts a TQDomNode into a TQDomComment. If the node is not a comment the returned object will be null.
.PP
See also isComment().
.SH "TQDomDocument TQDomNode::toDocument ()"
Converts a TQDomNode into a TQDomDocument. If the node is not a document the returned object will be null.
.PP
See also isDocument().

Converts a TQDomNode into a TQDomDocumentType. If the node is not a document type the returned object will be null.
.PP
See also isDocumentType().
.SH "TQDomElement TQDomNode::toElement ()"
Converts a TQDomNode into a TQDomElement. If the node is not an element the returned object will be null.
.PP
See also isElement().
.PP
Example: xml/outliner/outlinetree.cpp.
.SH "TQDomEntity TQDomNode::toEntity ()"
Converts a TQDomNode into a TQDomEntity. If the node is not an entity the returned object will be null.
.PP
See also isEntity().
.SH "TQDomEntityReference TQDomNode::toEntityReference ()"
Converts a TQDomNode into a TQDomEntityReference. If the node is not an entity reference, the returned object will be null.
.PP
