java 生成xml并转为字符串的方法

java 生成xml并转为字符串的方法

如下所示：

import javax.xml.parsers.DocumentBuilderFactory;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.transform.TransformerFactory;

import javax.xml.transform.OutputKeys;

import javax.xml.transform.Transformer;

import javax.xml.transform.dom.DOMSource;

import javax.xml.transform.stream.StreamResult;

import org.apache.commons.io.output.ByteArrayOutputStream;

import org.w3c.dom.Document;

import org.w3c.dom.Element;

public class test {

private String createXml() {

String xmlString = "";

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

try {

DocumentBuilder builder = factory.newDocumentBuilder();

Document document = builder.newDocument();

document.setXmlStandalone(true);

Element itemInfo = document.createElement("ItemInfo");

document.appendChild(itemInfo);

Element itemStatistics = document.createElement("ItemStatistics");

itemStatistics.setTextContent("商品统计");

itemInfo.appendChild(itemStatistics);

Element items = document.createElemenhttp://t("Items");

itemInfo.appendChild(items);

// 此处可以循环添加

Element item = document.createElement("Item");

items.appendChild(item);

Element itemName = document.createElement("ItemName");

itemName.setTextContent("iPhone");

item.appendChild(itemName);

Element itemNum = document.createElement("ItemNum");

itemNum.setTextContent("3");

item.appendChild(itemNum);

Element itemValue = document.createElement("ItemValue");

itemValue.setTextContent("1000000");

item.appendChild(itemValue);

Element remark = document.createElement("Remark");

remark.setTextContent("配送");

itemInfo.appendChild(redajBeUpFJmark);

TransformerFactory transFactory = TransformerFactory.newInstance();

Transformer transformer = transFactory.newTransformer();

transformer.setOutputProperty(OutputKeys.INDENT, "yes");

DOMSource domSource = new DOMSource(document);

// xml transform String

ByteArrayOutputStream bos = new ByteArrayOutputStream();

transformer.transform(domSource, new StreamResult(bos));

xmlString = bos.toString();

System.out.println(xmlString);

} catch (Exception e) {

e.printStackTrace();

}

return xmlString;

}

}

结果：

商品统计

iPhone

3

1000000

配送

去掉头文件

的办法暂时只能想到：

xmlString.substring(38)
