parse() is not returning a document

In my app, I am retrieving an xml file from the web, I want to parse it, display the title and the date and then later the body.

Variable ‘target’ is the web address of a specific xml file – at this point the variable ‘target’ has held the correct value
Variable ‘line’ is a string contain the body of the xml file

Code:

---

        public static <Uri> String getXML(String target){
                        String line = null;
                        try {
                                DefaultHttpClient httpClient = new DefaultHttpClient();
                                HttpPost httpPost = new HttpPost(target);
                                HttpResponse httpResponse = httpClient.execute(httpPost);
                                HttpEntity httpEntity = httpResponse.getEntity();
                                line = EntityUtils.toString(httpEntity);
                        } catch (UnsupportedEncodingException e) {
                                line = "<results status=\"error\"><msg>Can't connect to server</msg></results>";
                        } catch (MalformedURLException e) {
                                line = "<results status=\"error\"><msg>Can't connect to server</msg></results>";
                        } catch (IOException e) {
                                line="<results status=\"error\"><msg>Can't connect to server</msg></results>";
                        }
                        return line;
                }

---

It then goes to the following call Document doc = XMLfunctions.XMMLfromString(xml)

Upon access Variable ‘target’ still contains the characters of the xml file in a string format

The program then goes to XMLfromString(String xml) where xml is the returned value by getXML – this value is the actual xml file as a string – variable watching shows the correct characters in the string

Code:

---

public final static Document XMLfromString(String xml){
               
                Document doc = null;
                        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
try {
                                DocumentBuilder db = dbf.newDocumentBuilder();
                        InputSource is = new InputSource();
                        is.setCharacterStream(new StringReader(xml));

---

/* this fails, the string ‘is’ contains the correct characters from the xml file

Code:

---

doc = db.parse(is);

---

after parsing the variable watch shows a value of "doc = DocumentImpl(ID=83##########)+

Code:

---

                } catch (ParserConfigurationException e) {
                        System.out.println("XML parse error: " + e.getMessage());
                        return null;
                } catch (SAXException e) {
                        System.out.println("Wrong XML file structure: " + e.getMessage());
return null;
                } catch (IOException e) {
                        System.out.println("I/O exception: " + e.getMessage());
                        return null;
                }
                     
        return doc;
}

Any ideas or help would be greatly appreciated.
