我已经编写了一个解析器,用于解析HttpURLConnection中的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文件和网络文件完全相同…如果有人看的话: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:期望的名称(位置:java.io.InputStreamReader@476687中的START_TAG @ 1:309)
非常感谢您的帮助:)
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。
