DESCRIPTION

30       The QDomAttr class represents one attribute of a QDomElement.
31
32       For example, the following piece of XML produces an element with no
33       children, but two attributes:
34
35           <link href="http://www.trolltech.com" color="red" />
36
37       You can access the attributes of an element with code like this:
38
39           QDomElement e = //...
40           //...
41           QDomAttr a = e.attributeNode( "href" );
42           cout << a.value() << endl;                // prints "http://www.trolltech.com"
43           a.setValue( "http://doc.trolltech.com" ); // change the node's attribute
44           QDomAttr a2 = e.attributeNode( "href" );
45           cout << a2.value() << endl;               // prints "http://doc.trolltech.com"
46
47       This example also shows that changing an attribute received from an
48       element changes the attribute of the element. If you do not want to
49       change the value of the element's attribute you must use cloneNode() to
50       get an independent copy of the attribute.
51
52       QDomAttr can return the name() and value() of an attribute. An
53       attribute's value is set with setValue(). If specified() returns TRUE
54       the value was either set in the document or set with setValue();
55       otherwise the value hasn't been set. The node this attribute is
56       attached to (if any) is returned by ownerElement().
57

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

MEMBER FUNCTION DOCUMENTATION

QDomAttr::QDomAttr ()

67       Constructs an empty attribute.
68

QDomAttr::QDomAttr ( const QDomAttr & x )

70       Constructs a copy of x.
71
72       The data of the copy is shared (shallow copy): modifying one node will
73       also change the other. If you want to make a deep copy, use
74       cloneNode().
75

QDomAttr::~QDomAttr ()

77       Destroys the object and frees its resources.
78

bool QDomAttr::isAttr () const [virtual]

80       Returns TRUE.
81
82       Reimplemented from QDomNode.
83

QString QDomAttr::name () const [virtual]

85       Returns the attribute's name.
86

QDomNode::NodeType QDomAttr::nodeType () const [virtual]

88       Returns AttributeNode.
89
90       Reimplemented from QDomNode.
91

QDomAttr & QDomAttr::operator= ( const QDomAttr & x )

93       Assigns x to this DOM attribute.
94
95       The data of the copy is shared (shallow copy): modifying one node will
96       also change the other. If you want to make a deep copy, use
97       cloneNode().
98

QDomElement QDomAttr::ownerElement () const [virtual]

100       Returns the element node this attribute is attached to or a null node
101       if this attribute is not attached to any element.
102

void QDomAttr::setValue ( const QString & v ) [virtual]

104       Sets the attribute's value to v.
105
106       See also value().
107

bool QDomAttr::specified () const [virtual]

109       Returns TRUE if the attribute has either been expicitly specified in
110       the XML document or was set by the user with setValue(). Returns FALSE
111       if the value hasn't been specified or set.
112
113       See also setValue().
114

QString QDomAttr::value () const [virtual]

116       Returns the value of the attribute or QString::null if the attribute
117       has not been specified.
118
119       See also specified() and setValue().
