我已经编写了一个解析器,用于从HttpURLConnection解析XML文件.这很好.
问题:我需要重写此文件,以便从本地资源而不是从Internet加载xml文件,但是我无法使它正常工作…只是让您了解原始Web解析器的外观:
InputStream in=null;
URLConnection connection = url.openConnection();
HttpURLConnection httpconnection = (HttpURLConnection)connection;
int responseCode = httpconnection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
in = httpconnection.getInputStream();
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document dom = db.parse(in);
Element docEle = dom.getDocumentElement();
NodeList nl = docEle.getChildNodes();
for (int i = 0; i < nl.getLength(); i++) {
Node node = nl.item(i);
//START PARSING......
现在,这里是我用来尝试从位于资源文件夹中xml / myfile.xml的本地资源解析的代码:
InputStream in=null;
in = mParentActivity.getResources().openRawResource(R.xml.myfile);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document dom = builder.parse(in); // THIS IS WHERE I GET AN SAXParseException
Element root = dom.getDocumentElement();
NodeList nl = root.getChildNodes();
for (int i = 0; i < nl.getLength(); i++) {
Node node = nl.item(i);
//START PARSING......
本地xml文件和Web文件完全相同…如果有人看一下:http://agens.no/Eniro/Android/SEWheel/Category2.plist.xml
这是堆栈跟踪:
02-01 16:08:45.546:WARN / System.err(19703):org.xml.sax.SAXParseException:预期名称(java.io.InputStreamReader@47668728中的位置START_TAG @ 1:309)
非常感谢您的帮助:)
解决方法:
找到了答案.当文件是res / xml文件夹时,inputstream显示了很多无效字符.当我将它放在res / raw文件夹中时,它工作正常.
