[移动开发]Android DOM解析XML文件 最简单的例子

最简单的例子了

待解析的zzk.xml文件，只有一个参数utc。

<?xml version="1.0" encoding="UTF-8"?>
	<zzk>
    	<config utc = "1625043055"></config>
	</zzk>

解析函数

    public static String queryXML(String path)
    {
        try {
            DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder dbBuilder = dbFactory.newDocumentBuilder();
            Document doc = dbBuilder.parse(new FileInputStream(path));
            NodeList nList = doc.getElementsByTagName("config");
            Element ielement = (Element) nList.item(0);
            return ielement.getAttribute("utc");
        } catch (Exception e) {
            e.printStackTrace();
        }
        return "";
    }

使用

	String path = getStoragePath(mContext);
	String strFilePath = path + "/zzk.xml";
	utc_xml =queryXML(strFilePath);	//得到xml里的utc
