String xml = "<div><img href=""></div>";

and not converted to document object through below code

DocumentBuilderFactory factory =
DocumentBuilderFactory.    DocumentBuilder builder;
builder = factory.newDocumentBuilder();  
Document doc = builder.parse(xml); 

the error is

The markup in the document preceding the root element must be well-formed.

Answer 1

The error message means exactly what it says. End tags in XML are not optional; your input is therefore not well-formed XML, and therefore the parser rejects it.
