Detailed Description

\reentrant

The QDomCharacterData class represents a generic string in the DOM.

\inmodule QtXml

Character data as used in XML specifies a generic data string. More specialized versions of this class are QDomText, QDomComment and QDomCDATASection.

The data string is set with setData() and retrieved with data(). You can retrieve a portion of the data string using substringData(). Extra data can be appended with appendData(), or inserted with insertData(). Portions of the data string can be deleted with deleteData() or replaced with replaceData(). The length of the data string is returned by length().

The node type of the node containing this character data is returned by nodeType().

Constructor & Destructor Documentation

◆ QDomCharacterData() [1/2]

QDomCharacterData::QDomCharacterData ( )

Constructs an empty character data object.

Definition at line 3422 of file qdom.cpp.

◆ QDomCharacterData() [2/2]

QDomCharacterData::QDomCharacterData ( const QDomCharacterData & 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 3433 of file qdom.cpp.

◆ appendData()

void QDomCharacterData::appendData ( const QString & arg )

Appends the string arg to the stored string.

◆ data()

QString QDomCharacterData::data ( ) const

Returns the string stored in this object.

If the node is a \l{isNull()}{null node}, it will return an empty string.

		unsigned long	count
	)

Deletes a substring of length count from position offset.

◆ length()

int QDomCharacterData::length ( ) const

Definition at line 3477 of file qdom.cpp.

References IMPL, and QDomNode::impl.

◆ nodeType()

QDomNode::NodeType QDomCharacterData::nodeType ( ) const

Returns the type of node this object refers to (i.e.

TextNode, CDATASectionNode, CommentNode or CharacterDataNode). For a \l{isNull()}{null node}, returns CharacterDataNode.

Here is the call graph for this function:

◆ operator=()

QDomCharacterData & QDomCharacterData::operator= ( const QDomCharacterData & )

default

Assigns x to this character data.

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().

◆ replaceData()

void QDomCharacterData::replaceData	(	unsigned long	offset,
		unsigned long	count,
		const QString &	arg
	)

Replaces the substring of length count starting at position offset with the string arg.

◆ setData()

void QDomCharacterData::setData ( const QString & v )

Sets this object's string to v.

Here is the call graph for this function:

◆ substringData()

QString QDomCharacterData::substringData	(	unsigned long	offset,
		unsigned long	count
	)

Returns the substring of length count from position offset.
