DESCRIPTION
The QDomElement class represents one element in the DOM
tree.
Elements have a name() and zero or more attributes
associated with them.
Attributes of the element 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.
For further information about the Document Objct Model see
http://www.w3.org/TR/REC-DOM-Level-1/. For a more general
introduction of the DOM implementation see the
QDomDocument documentation.
MEMBER FUNCTION DOCUMENTATIONTrolltech AS 13 June 2001 1
QDomElement(3qt)QDomElement(3qt)QDomElement::QDomElement ()
Constructs an empty element. Use the
QDomDocument::createElement() function to construct
elements with content.
QDomElement::QDomElement ( const QDomElement & x )
Copy constructor.
The data of the copy is shared: modifying one will also
change the other. If you want to make a real copy, use
cloneNode() instead.
QDomElement::~QDomElement ()
Destructor.
QString QDomElement::attribute ( const QString & name, const
QString & defValue = QString::null ) const
Returns the attribute with the name name. If the attribute
does not exist defValue is returned.
See also setAttribute(), attributeNode() and
setAttributeNode().
QDomAttr QDomElement::attributeNode ( const QString & name )
Returns the QDomAttr object that corresponds to the
attribute with the name name. If no such attribute exists
a null object is returned.
See also setAttributeNode(), attribute() and
setAttribute().
QDomNamedNodeMap QDomElement::attributes () const [virtual]
Returns a QDomNamedNodeMap containing all attributes for
this element.
See also attribute(), setAttribute(), attributeNode() and
setAttributeNode().
Reimplemented from QDomNode.
QDomNodeList QDomElement::elementsByTagName ( const QString &
tagname ) const [virtual]
Returns a QDomNodeList containing all descendant elements
of this element with the name tagname. The order they are
in the node list, is the order they are encountered in a
preorder traversal of the element tree.
bool QDomElement::hasAttribute ( const QString & name ) const
Returns TRUE is this element has an attribute with the
name name, otherwise FALSE.
bool QDomElement::isElement () const [virtual]
Returns TRUE.

QDomElement(3qt)QDomElement(3qt)
Reimplemented from QDomNode.
QDomNode::NodeType QDomElement::nodeType() const [virtual]
Returns ElementNode.
Reimplemented from QDomNode.
void QDomElement::normalize ()
Calling normalize() on an element brings all its children
into a standard form. This means, that adjacent QDomText
objects will be merged to one text object
(QDomCDATASection nodes are not merged).
QDomElement& QDomElement::operator= ( const QDomElement & x )
Assignment operator.
The data of the copy is shared: modifying one will also
change the other. If you want to make a real copy, use
cloneNode() instead.
void QDomElement::removeAttribute ( const QString & name )
Removes the attribute with the name name from this
element.
See also setAttribute() and attribute().
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 )
Sets the attribute with the name name to the string value.
If the attribute does not exist, a new one is created.
void QDomElement::setAttribute ( const QString & name, double
value )
This is an overloaded member function, provided for
convenience. It differs from the above function only in
what argument(s) it accepts.
void QDomElement::setAttribute ( const QString & name, int value
)
This is an overloaded member function, provided for
convenience. It differs from the above function only in
what argument(s) it accepts.
void QDomElement::setAttribute ( const QString & name, uint value
)
This is an overloaded member function, provided for
convenience. It differs from the above function only in
Trolltech AS 13 June 2001 3
QDomElement(3qt)QDomElement(3qt)
what argument(s) it accepts.
QDomAttr QDomElement::setAttributeNode ( const QDomAttr & newAttr
)
Adds the attribute newAttr to this element.
If an attribute with the name newAttr exists in the
element, the function returns this attribute; otherwise
the function returns a null attribute.
See also attributeNode().
void QDomElement::setTagName ( const QString & name )
Sets the tag name of this element.
See also tagName().
QString QDomElement::tagName () const
Returns the tag name of this element. For an XML element
like
<img src="myimg.png">
the tagname would return "img".
See also setTagName().
QString QDomElement::text () const
Returns the text contained inside this element.
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 evaluates only
QDomText and QDomCDATASection objects.
