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());

	}
