XML String to Document

[Paulo Carvalho]

Hello

I have a XML String which I want to convert to a Document object. To do so I made a method "stringToDocument(final String xmlSource)".

public static Document stringToDocument(final String xmlSource) 
    	throws SAXException, ParserConfigurationException, IOException {
		DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
		DocumentBuilder builder = factory.newDocumentBuilder();
		
		return builder.parse(new InputSource(new StringReader(xmlSource)));
	}

However I have a problem. My XML String have the following header:

<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>

When I convert my XML String to a Document object, if I print the resulting Document into a String it has the following header:

<?xml version="1.0" encoding="UTF-8"?>

This causes me problems for next processes that I apply to the generated XML.

How can I convert my XML String to a Document keeping the original header?

Thanks
Regards

"Keeping the original header" isn't a reasonable requirement. The prolog is supposed to describe the document it is attached to, and that should be your requirement. So the encoding should declare the actual encoding of the document, and you should only have a "standalone" attribute in your prolog if the document is standalone.
