Question

请教setText和addText的区别

Answer 1

javadoc
引用setText(Stringtext)
SetsthetextdataofthisnodeorthismethodwillthrowanUnsupportedOperationExceptionifitisread-only.

addText(Stringtext)
AddsanewTextnodewiththegiventexttothiselement.

实现
publicElementaddText( www.hnnedu.com Stringtext){Textnode=getDocumentFactory().createText(text);addNewNode(node);returnthis;}

publicvoidsetText(Stringtext){ListallContent=contentList();if(allContent!=null){Iteratorit=allContent.iterator();while(it.hasNext()){Nodenode=(Node)it.next();switch(node.getNodeType()){case3:case4:case5:it.remove();}}}addText(text);}

如果是Element的话没什么区别
