How to ignore Fatal Errors using java Sax Parer

Question

I am parsing html using java sax parser, its mostly well formatted but not all tags are terminated,
unfortunately I cannot change the source.
Is it possible to tell the java Sax Parser to ignore Fatal Errors ?

Errors like:

SAXParseException; 
The entity "nbsp" was referenced, but not declared.
The element type "img" must be terminated by the matching end-tag "</img>". 
The element type "meta" must be terminated by the matching end-tag "</meta>".

This is the code I am using:

           DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
           factory.setIgnoringComments(true);
           //factory.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, false);
           // factory.setNamespaceAware(true);
            DocumentBuilder builder = factory.newDocumentBuilder();
            InputSource is = new InputSource(new StringReader(xml));
            Document doc = builder.parse(is);
