拼XML的工具类

public class XmlStringer {
	public XmlStringer() {
		builder=new StringBuilder();
	}
	
	private StringBuilder builder;
	public XmlStringer startNode(String name){
		builder.append("<"+name+">");
		return this;
	}
	public XmlStringer endNode(String name){
		builder.append("</"+name+">");
		return this;
	}
	public XmlStringer attribute(String name,String value){
		builder.replace(builder.length()-1, builder.length(), " "+name+"='"+value+"'>");
		return this;
	}
	public XmlStringer attribute(String name,int value){
		builder.replace(builder.length()-1, builder.length(), " "+name+"='"+value+"'>");
		return this;
	}
	
	public XmlStringer text(String text){
		builder.append(text);
		return this;
	}
	public XmlStringer text(int text){
		builder.append(text);
		return this;
	}
	public XmlStringer text(boolean text){
		builder.append(text);
		return this;
	}
	public XmlStringer text(byte[] data) {
		builder.append(new String(data));
		return this;
		
	}
	public void clear(){
		builder.delete(0, builder.length());
	}
	@Override
	public String toString() {
		return builder.toString();
	}
}

用法：

public static void main(String[] args) {
		XmlStringer stringer=new XmlStringer();
		stringer.startNode("tobacco");
		stringer.attribute("action", "tasksave");
		stringer.attribute("taskid", "000000000018878");
			stringer.startNode("taskstatus");
			stringer.text("2");
			stringer.endNode("taskstatus");
		
		
			stringer.startNode("subtask");
			stringer.attribute("subtaskid", "77777777777");
			stringer.attribute("subtaskstatus", "9");
			stringer.attribute("type", "m2_0");
			
				stringer.startNode("biaozhun");
				
					stringer.startNode("appraise");
					
						stringer.startNode("selected_index");
						stringer.text("0");
						stringer.endNode("selected_index");
						
						stringer.startNode("comment");
						stringer.text(1);
						stringer.endNode("comment");
					
					stringer.endNode("appraise");
				
				stringer.endNode("biaozhun");
			
			
			
			stringer.endNode("subtask");
		
		stringer.endNode("tobacco");
		System.out.println(stringer.toString());
	}
