DOMParser problem

Question

I have a servlet that does a stock quote lookup from a service and it worked perfectly. Unfortunately this site was for personal use only. The code looked like this:
DOMParser parser = new DOMParser();
URL url = new URL("http://www.xignite.com/xQuotes.asmx/GetQuotes?Symbol=" + symbol);
URLConnection connection = url.openConnection();
connection.connect();
parser.parse(new InputSource(connection.getInputStream()));
Document document = parser.getDocument();
Node n = document.getLastChild();
NodeList nodeList=document.getElementsByTagName("Quote");
I found another service that is free for personal or commercial use and I'm trying to do the same thing. Unfortunately I'm not getting the results. Seems like it's coming back as null. The code is pretty much the same:
DOMParser parser = new DOMParser();
URL url = new URL("http://www.webservicex.net/stockquote.asmx/GetQuote?symbol=" + symbol);
URLConnection connection = url.openConnection();
connection.connect();
parser.parse(new InputSource(connection.getInputStream()));
Document document = parser.getDocument();
Node n = document.getLastChild();
NodeList nodeList=document.getElementsByTagName("Stock");
The interesting thing I found was the difference when looking at the source of the returned pages when hitting them directly with a browser. The first one is nicely formatted and looks like this:
<?xml version="1.0" encoding="utf-8"?>
<ArrayOfQuote xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.xignite.com/services/">
<Quote>

<Previous_Close>28.35</Previous_Close>
<Bid>28.35</Bid>
<Bid_Size>200</Bid_Size>
<Ask>28.35</Ask>
<Ask_Size>100</Ask_Size>
<High_52_Weeks>30.00</High_52_Weeks>
<Low_52_Weeks>24.01</Low_52_Weeks>
</Quote>
</ArrayOfQuote>
The second, the one I can't get to work, looks like this, except the <> are actually "& l t ;" and "& g t ;" (no spaces of course....).
<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://www.webserviceX.NET/"><StockQuotes><Stock><Symbol>GETQUOTE?SYMBOL=PKG</Symbol><Last>4.84</Last><Date>6/21/2004</Date><Time>2:48pm</Time><Change>-0.01</Change><Open>4.94</Open><High>4.94</High><Low>4.79</Low><Volume>346739</Volume><MktCap>330.8M</MktCap><PreviousClose>4.85</PreviousClose><PercentageChange>-0.21%</PercentageChange><AnnRange>4.46 - 12.00</AnnRange><Earns>0.49</Earns><P-E>9.90</P-E><Name>WESTELL TECH A</Name></Stock></StockQuotes></string>
Could that be causing the problem?
Any suggestions on how to handle it?
Any help is greatly appreciated.

Yep, when I look at the source I see the escape
characters. (how did you get them to show up instead
of showing up as <>? I tried code and pre tags.)Simple I just put &amp;lt; and so on.

I've wasted a ton of time messing around with, don't
suppose you could give me a hint or a little boost on
how to put it through a filter and substitute the
escapes.
I don't know of any prebuilt solution. I think you'll have to write your own filter.
Perhaps simplest to use ByteArrayInputStream / ByteArrayOutputStream to buffer the data and a simple state based lexical processor.
