Detailed Description

The QDomText class represents text data in the parsed XML document.

Note
This class or function is reentrant.
Attention
Module: QtXml

You can split the text in a QDomText object over two QDomText objecs with splitText().

For further information about the Document Object Model see Level 1 and Level 2 Core. For a more general introduction of the DOM implementation see the QDomDocument documentation.

Constructors and Destructors

◆ QDomText() [1/3]

QDomText::QDomText ( )

Constructs an empty QDomText object.

To construct a QDomText with content, use QDomDocument::createTextNode().

Definition at line 5356 of file qdom.cpp.

5357  : QDomCharacterData()
5358 {
5359 }
QDomCharacterData()
Constructs an empty character data object.
Definition: qdom.cpp:4056

◆ QDomText() [2/3]

QDomText::QDomText ( const QDomText 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().

Definition at line 5368 of file qdom.cpp.

5369  : QDomCharacterData(x)
5370 {
5371 }
QDomCharacterData()
Constructs an empty character data object.
Definition: qdom.cpp:4056

◆ QDomText() [3/3]

QDomText::QDomText ( QDomTextPrivate n)
private

Definition at line 5373 of file qdom.cpp.

5374  : QDomCharacterData(n)
5375 {
5376 }
QDomCharacterData()
Constructs an empty character data object.
Definition: qdom.cpp:4056

Functions

◆ nodeType()

QDomNode::NodeType QDomText::nodeType ( ) const
inline

Returns TextNode.

Definition at line 545 of file qdom.h.

545 { return TextNode; }

◆ operator=()

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

Assigns x to this DOM text.

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().

Definition at line 5385 of file qdom.cpp.

5386 {
5387  return (QDomText&) QDomNode::operator=(x);
5388 }
The QDomText class represents text data in the parsed XML document.
Definition: qdom.h:534
QDomNode & operator=(const QDomNode &)
Assigns a copy of n to this DOM node.
Definition: qdom.cpp:2096

◆ splitText()

QDomText QDomText::splitText ( int  offset)

Splits this DOM text object into two QDomText objects.

This object keeps its first offset characters and the second (newly created) object is inserted into the document tree after this object with the remaining characters.

The function returns the newly created object.
