public static Document parse ( Path path , boolean validation ) throws IOException , SAXException , IllegalArgumentException { return parse ( path . toFile ( ) , validation ) ; }
Parses XML to a W3C Document object with activated or deactivated validation.
In case of validation, a correct header is needed. Therefore, we try to fix the
header before we try to parse the input. Also, an error handler is activated
that throws {@link SAXException} if an error due the validation or parsing process
will be thrown.
<p>
In case of deactivated validation, there will be no SAXException occur!

@param path       to a XML file
@param validation turn validation on or off
@return Document of XML object.
@throws IOException              if an IO error occurs
@throws SAXException             only occurs when validation is on and an error due parsing the document occurred.
@throws IllegalArgumentException if the argument is null
