详细描述

The QDomCharacterData class represents a generic string in the DOM.

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 ().

方法文档编制

QDomCharacterData.init ( self )

Constructs an empty character data object.

QDomCharacterData.init ( self , QDomCharacterData x )

构造副本为 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 ().

QDomCharacterData.appendData ( self , QString arg )

Appends the string arg to the stored string.

QString QDomCharacterData.data ( self )

Returns the string stored in this object.

If the node is a null 节点 , it will return an empty string.

另请参阅 setData ().

QDomCharacterData.deleteData ( self , int offset , int count )

Deletes a substring of length count from position offset .

QDomCharacterData.insertData ( self , int offset , QString arg )

Inserts the string arg into the stored string at position offset .

int QDomCharacterData.length ( self )

Returns the length of the stored string.

QDomNode.NodeType QDomCharacterData.nodeType ( self )

Returns the type of node this object refers to (i.e. TextNode , CDATASectionNode , CommentNode or CharacterDataNode ). For a null 节点 , returns CharacterDataNode .

QDomCharacterData.replaceData ( self , int offset , int count , QString arg )

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

QDomCharacterData.setData ( self , QString)

Sets this object's string to v .

另请参阅 data ().

QString QDomCharacterData.substringData ( self , int offset , int count )

Returns the substring of length count from position offset .
