java 生成xml并转为字符串的方法
如下所示：
importjavax.xml.parsers.DocumentBuilderFactory;
importjavax.xml.parsers.DocumentBuilder;
importjavax.xml.transform.TransformerFactory;
importjavax.xml.transform.OutputKeys;
importjavax.xml.transform.Transformer;
importjavax.xml.transform.dom.DOMSource;
importjavax.xml.transform.stream.StreamResult;
importorg.apache.commons.io.output.ByteArrayOutputStream;
importorg.w3c.dom.Document;
importorg.w3c.dom.Element;
publicclasstest{
privateStringcreateXml(){
StringxmlString="";
DocumentBuilderFactoryfactory=DocumentBuilderFactory.newInstance();
try{
DocumentBuilderbuilder=factory.newDocumentBuilder();
Documentdocument=builder.newDocument();
document.setXmlStandalone(true);
ElementitemInfo=document.createElement("ItemInfo");
document.appendChild(itemInfo);
ElementitemStatistics=document.createElement("ItemStatistics");
itemStatistics.setTextContent("商品统计");
itemInfo.appendChild(itemStatistics);
Elementitems=document.createElement("Items");
itemInfo.appendChild(items);
//此处可以循环添加
Elementitem=document.createElement("Item");
items.appendChild(item);
ElementitemName=document.createElement("ItemName");
itemName.setTextContent("iPhone");
item.appendChild(itemName);
ElementitemNum=document.createElement("ItemNum");
itemNum.setTextContent("3");
item.appendChild(itemNum);
ElementitemValue=document.createElement("ItemValue");
itemValue.setTextContent("1000000");
item.appendChild(itemValue);
Elementremark=document.createElement("Remark");
remark.setTextContent("配送");
itemInfo.appendChild(remark);
TransformerFactorytransFactory=TransformerFactory.newInstance();
Transformertransformer=transFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT,"yes");
DOMSourcedomSource=newDOMSource(document);
//xmltransformString
ByteArrayOutputStreambos=newByteArrayOutputStream();
transformer.transform(domSource,newStreamResult(bos));
xmlString=bos.toString();
System.out.println(xmlString);
}catch(Exceptione){
e.printStackTrace();
}
returnxmlString;
}
}
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)
