如何从java创建xml文件
我正在构建一个简单的java程序来创建XML文件。 我正在构建此代码：如何从java创建xml文件,java,xml,xml-parsing,Java,Xml,Xml Parsing,我正在构建一个简单的java程序来创建XML文件。 我正在构建此代码： public static void creaXMLOrdine(OrdiniNuovo ordine,String codiceNegozio, String pathFile){ try{ DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();

<ORDER>
<INFO>
<Id>123456</Id>
<Value>99999</Value>

</OTHERS>
</ORDER>
哪一行可能是Utility.creaXMLOrdineUtility.java:142？英文变量名会使代码更容易理解。
