Referring to this: XmlPullParser

Are you searching something like this:

if(eventType == XmlPullParser.TEXT) 
{
    String text = xpp.getText();
    if( text.contains("&") )
        text = text.replace("&", "&amp;");
    if( text.contains("<" ) )
        text = text.replace("<", "&lt;");
}

EDIT: Here's how you can fetch the xml in a String:

String xmlStr = "";

HttpGet uri = new HttpGet(params[0]);

DefaultHttpClient client = new DefaultHttpClient();

HttpResponse resp = client.execute(uri);
StatusLine status = resp.getStatusLine();
if( status.getStatusCode() == 200 )
{
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = factory.newDocumentBuilder();
    Document doc = builder.parse(resp.getEntity().getContent());

    TransformerFactory transformerfactory = TransformerFactory.newInstance();
    Transformer transformer = transformerfactory.newTransformer();
    transformer.setOutputProperty(OutputKeys.INDENT, "yes");

    StringWriter stringWriter = new StringWriter();
    transformer.transform(new DOMSource(doc), new StreamResult(stringWriter));  

    // Now you can fix the invalid characters in your xml and put it in the parser  
    xmlStr = stringWriter.toString();
}
