DESCRIPTION
       The QDomElement class represents one element in the DOM tree.

       Elements have a tagName() and zero or more attributes associated with
       them. The tag name can be changed with setTagName().

       Element attributes are represented by QDomAttr objects that can be
       queried using the attribute() and attributeNode() functions. You can
       set attributes with the setAttribute() and setAttributeNode()
       functions. Attributes can be removed with removeAttribute(). There are
       namespace-aware equivalents to these functions, i.e. setAttributeNS(),
       setAttributeNodeNS() and removeAttributeNS().

       If you want to access the text of a node use text(), e.g.

	   QDomElement e = //...
	   //...
	   QString s = e.text()
       The text() function operates recursively to find the text (since not
       all elements contain text). If you want to find all the text in all of
       a node's children, iterate over the children looking for QDomText
       nodes, e.g.

	   QString text;
	   QDomElement element = doc.documentElement();
	   for( QDomNode n = element.firstChild(); !n.isNull(); n = n.nextSibling() )
	   {
	       QDomText t = n.toText();
	       if ( !t.isNull() )
		   text += t.data();
	   }
       Note that we attempt to convert each node to a text node and use text()
       rather than using firstChild().toText().data() or n.toText().data()
       directly on the node, because the node may not be a text element.

       You can get a list of all the decendents of an element which have a
       specified tag name with elementsByTagName() or elementsByTagNameNS().

       Level-2-Core/. For a more general introduction of the DOM
       implementation see the QDomDocument documentation.

MEMBER FUNCTION DOCUMENTATION
QDomElement::QDomElement ()
       Constructs an empty element. Use the QDomDocument::createElement()
       function to construct elements with content.

QDomElement::QDomElement ( const QDomElement & x )
       Constructs a copy of x.

       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().

QDomElement::~QDomElement ()
       Destroys the object and frees its resources.

QString QDomElement::attribute ( const QString & name, const QString &
       defValue = QString::null ) const
       Returns the attribute called name. If the attribute does not exist
       defValue is returned.

       See also setAttribute(), attributeNode(), setAttributeNode(), and
       attributeNS().

QString QDomElement::attributeNS ( const QString nsURI, const QString &
       localName, const QString & defValue ) const
       Returns the attribute with the local name localName and the namespace
       URI nsURI. If the attribute does not exist defValue is returned.

       See also setAttributeNS(), attributeNodeNS(), setAttributeNodeNS(), and
       attribute().

QDomAttr QDomElement::attributeNode ( const QString & name )
       Returns the QDomAttr object that corresponds to the attribute called
       name. If no such attribute exists a null attribute is returned.

       See also setAttributeNode(), attribute(), setAttribute(), and
       attributeNodeNS().

QDomAttr QDomElement::attributeNodeNS ( const QString & nsURI, const QString &
       localName )
       Returns the QDomAttr object that corresponds to the attribute with the
       local name localName and the namespace URI nsURI. If no such attribute
       exists a null attribute is returned.

       See also setAttributeNode(), attribute(), and setAttribute().

QDomNamedNodeMap QDomElement::attributes () const [virtual]
       Returns a QDomNamedNodeMap containing all this element's attributes.

       See also attribute(), setAttribute(), attributeNode(), and
       setAttributeNode().

       Reimplemented from QDomNode.

QDomNodeList QDomElement::elementsByTagName ( const QString & tagname ) const
       [virtual]
       Returns a QDomNodeList containing all descendent elements of this
       element that are called tagname. The order they are in the node list is
       the order they are encountered in a preorder traversal of the element
       tree.

       See also elementsByTagNameNS() and QDomDocument::elementsByTagName().

QDomNodeList QDomElement::elementsByTagNameNS ( const QString & nsURI, const
       QString & localName ) const [virtual]
       Returns a QDomNodeList containing all the descendent elements of this
       element with the local name localName and the namespace URI nsURI. The
       order they are in the node list is the order they are encountered in a
       preorder traversal of the element tree.

       See also elementsByTagName() and QDomDocument::elementsByTagNameNS().

bool QDomElement::hasAttribute ( const QString & name ) const
       Returns TRUE if this element has an attribute called name; otherwise
       returns FALSE.

bool QDomElement::hasAttributeNS ( const QString & nsURI, const QString &
       localName ) const
       Returns TRUE if this element has an attribute with the local name
       localName and the namespace URI nsURI; otherwise returns FALSE.

bool QDomElement::isElement () const [virtual]
       Returns TRUE.

       Reimplemented from QDomNode.

QDomNode::NodeType QDomElement::nodeType () const [virtual]
       Returns ElementNode.

       Reimplemented from QDomNode.

QDomElement & QDomElement::operator= ( const QDomElement & x )
       Assigns x to this DOM element.

       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().

void QDomElement::removeAttribute ( const QString & name )
       Removes the attribute called name name from this element.

       See also setAttribute(), attribute(), and removeAttributeNS().

void QDomElement::removeAttributeNS ( const QString & nsURI, const QString &
       localName )
       Removes the attribute with the local name localName and the namespace
       URI nsURI from this element.

       See also setAttributeNS(), attributeNS(), and removeAttribute().

QDomAttr QDomElement::removeAttributeNode ( const QDomAttr & oldAttr )
       Removes the attribute oldAttr from the element and returns it.

       See also attributeNode() and setAttributeNode().

void QDomElement::setAttribute ( const QString & name, const QString & value )

       Adds an attribute called name with value value. If an attribute with
       the same name exists, its value is replaced by value.

       See also attribute(), setAttributeNode(), and setAttributeNS().

void QDomElement::setAttribute ( const QString & name, int value )
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

void QDomElement::setAttribute ( const QString & name, uint value )
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

void QDomElement::setAttribute ( const QString & name, long value )
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

void QDomElement::setAttribute ( const QString & name, ulong value )
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

void QDomElement::setAttribute ( const QString & name, double value )
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

void QDomElement::setAttributeNS ( const QString nsURI, const QString & qName,
       const QString & value )
       Adds an attribute with the qualified name qName and the namespace URI
       nsURI with the value value. If an attribute with the same local name
       and namespace URI exists, its prefix is replaced by the prefix of qName
       and its value is repaced by value.

       Although qName is the qualified name, the local name is used to decide
       if an existing attribute's value should be replaced.

       See also attributeNS(), setAttributeNodeNS(), and setAttribute().

void QDomElement::setAttributeNS ( const QString nsURI, const QString & qName,
       int value )
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

void QDomElement::setAttributeNS ( const QString nsURI, const QString & qName,
       uint value )
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

void QDomElement::setAttributeNS ( const QString nsURI, const QString & qName,
       long value )
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

void QDomElement::setAttributeNS ( const QString nsURI, const QString & qName,
       ulong value )
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

void QDomElement::setAttributeNS ( const QString nsURI, const QString & qName,
       double value )
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

QDomAttr QDomElement::setAttributeNode ( const QDomAttr & newAttr )
       Adds the attribute newAttr to this element.

       If the element has another attribute that has the same name as newAttr,
       this function replaces that attribute and returns it; otherwise the
       function returns a null attribute.

       See also attributeNode(), setAttribute(), and setAttributeNodeNS().

QDomAttr QDomElement::setAttributeNodeNS ( const QDomAttr & newAttr )
       Adds the attribute newAttr to this element.

       If the element has another attribute that has the same local name and
       namespace URI as newAttr, this function replaces that attribute and
       returns it; otherwise the function returns a null attribute.

       See also attributeNodeNS(), setAttributeNS(), and setAttributeNode().

void QDomElement::setTagName ( const QString & name )
       Sets this element's tag name to name.

       See also tagName().

QString QDomElement::tagName () const
       Returns the tag name of this element. For an XML element like this:

	   <img src="myimg.png">
       the tagname would return "img".

       See also setTagName().

QString QDomElement::text () const
       Returns the element's text or QString::null.

       Example:

	   <h1>Hello <b>Qt</b> <![CDATA[<xml is cool>]]></h1>

       The function text() of the QDomElement for the <h1> tag, will return
       "Hello Qt <xml is cool>".

       Comments are ignored by this function. It only evaluates QDomText and
       QDomCDATASection objects.
