.SH DESCRIPTION
|
|
The QDomNodeList class is a list of QDomNode objects.
|
|
.PP
|
|
Lists can be obtained by QDomDocument::elementsByTagName() and QDomNode::childNodes(). The Document Object Model (DOM) requires these lists to be "live": whenever you change the underlying document, the contents of the list will get updated.
|
|
.PP
|
|
You can get a particular node from the list with item(). The number of items in the list is returned by count() (and by length()).
|
|
.PP
|
|
For further information about the Document Object Model see http://www.w3.org/TR/REC-DOM-Level-1/ and http://www.w3.org/TR/DOM-Level-2-Core/. For a more general introduction of the DOM implementation see the QDomDocument documentation.
|
|
.PP
|
|
See also QDomNode::childNodes(), QDomDocument::elementsByTagName(), and XML.
|
|
.SH MEMBER FUNCTION DOCUMENTATION
|
|
.SH "QDomNodeList::QDomNodeList ()"
|
|
Creates an empty node list.
|
|
.SH "QDomNodeList::QDomNodeList ( const QDomNodeList & n )"
|
|
Constructs a copy of \fIn\fR.
|
|
.SH "QDomNodeList::~QDomNodeList ()\fC [virtual]\fR"
|
|
Destroys the object and frees its resources.
|
|
.SH "uint QDomNodeList::count () const"
|
|
Returns the number of nodes in the list.
|
|
.PP
|
|
This function is the same as length().
|
|
.SH "QDomNode QDomNodeList::item ( int index ) const\fC [virtual]\fR"
|
|
Returns the node at position \fIindex\fR.
|
|
.PP
|
|
If \fIindex\fR is negative or if \fIindex\fR >= length() then a null node is returned (i.e. a node for which QDomNode::isNull() returns TRUE).
|
|
.PP
|
|
See also count().
|
|
.SH "uint QDomNodeList::length () const\fC [virtual]\fR"
|
|
Returns the number of nodes in the list.
|
|
.PP
|
|
This function is the same as count().
|
|
.SH "bool QDomNodeList::operator!= ( const QDomNodeList & n ) const"
|
|
Returns TRUE the node list \fIn\fR and this node list are not equal; otherwise returns FALSE.
|
|
.SH "QDomNodeList & QDomNodeList::operator= ( const QDomNodeList & n )"
|
|
Assigns \fIn\fR to this node list.
|
|
.SH "bool QDomNodeList::operator== ( const QDomNodeList & n ) const"
|
|
Returns TRUE if the node list \fIn\fR and this node list are equal;
|
|
otherwise returns FALSE.
