My code was working fine yesterday, but I start it up again today and am getting the error

org.apache.harmony.xml.ExpatParser$ParseException: At line 1, column 0: not well-formed (invalid token)

The xml in question doesn’t have any funky characters. It is stored in a String variable called “xml”. To be fair, I wasn’t really sure how to deal with that and was just going off of some tutorials, but here was my attempt.

out = new PrintWriter(mySocket.getOutputStream(), true);
BufferedReader br = new BufferedReader(new InputStreamReader(mySocket.getInputStream(), "US-ASCII"));
InputStream is = mySocket.getInputStream();

...
String xml = the stuff that was read in with br.read();
...

SAXParserFactory saxPF = SAXParserFactory.newInstance();
SAXParser saxP = saxPF.newSAXParser();
XMLReader xmlR = saxP.getXMLReader();

DataHandler myDataHandler = new DataHandler();
xmlR.setContentHandler(myDataHandler);
xmlR.parse(new InputSource(new StringReader(xml)));
myData = myDataHandler.getData();

Where did I go wrong?

Update: The xml starts with

<?xml version="1.0" standalone="yes"?>

so it doesn’t seem that “line 1, column 0” actually has anything wrong with it.

Update 2: I found that is.available() is returning 0…. How do I make do with the fixing?

    I’m not sure what the problem was in the end, but I changed several things and have it somewhat working. Here’s what I changed:

    I changed

    BufferedReader br = new BufferedReader(new InputStreamReader(mySocket.getInputStream(), "US-ASCII"));
InputStream is = mySocket.getInputStream();

    to

    BufferedInputStream in = new BufferedInputStream(mySocket.getInputStream());

    And I didn’t include this in the original question (it was part of the “…”), but I got rid of the condition

    if(in.available()>0)

    because it was returning 0 even though read() worked just find without it. This is probably just a temporary hack though, and I’ll need to figure out why it’s returning 0 and find a legitimate fix…
