I tried that meanwhile ;-) and it "works". But this is the stream that comes
directly from the Google Reader service and the standard SDK works with it.
But that means parsing each line ... or writing my own decorator to clean it
up, wouldn't it.
static Document parseXMLfromInputStream(InputStream is, Context context)
throws ParserConfigurationException, FactoryConfigurationError, IOException,
SAXException {
Timing t = U.startTiming("parseXMLFromInputStream");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = dbf.newDocumentBuilder();
StringBuilder sb = new StringBuilder();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(is,
"UTF-8"), 8 * 1024);
String line;
while ((line = bufferedReader.readLine()) != null) {
sb.append(line.replaceAll("]]>", "]]>") + "\n");
}
bufferedReader.close();
//PrintWriter pw = new PrintWriter(new
FileWriter("/data/data/com.newsrob/files/test.output.xml"));
//pw.print(sb);
//pw.close();
//BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"),
8 * 1024);
//BufferedReader br = new BufferedReader(new
FileReader("/data/data/com.newsrob/files/test.output.xml"));
Document d = null;
try {
d = builder.parse(new InputSource(new StringReader(sb.toString())));
} catch (SAXParseException e) {
Log.e(TAG, "Exception during parsing:", e);
Intent i = new Intent();
i.setClass(context, ShowGoogleErrorActivity.class);
[..]
}
//br.close();
t.stop();
return d;
}
