        public void startElement​(java.lang.String uri,
                         java.lang.String localName,

        Receive notification of the start of an element. Caches the element as currentElement, so that it will be stored as a map key when the corresponding value will be read.
        Specified by:
        startElement in interface org.xml.sax.ContentHandler
        Overrides:
        startElement in class org.xml.sax.helpers.DefaultHandler
        Parameters:
        uri - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.
        localName - The local name (without prefix), or the empty string if Namespace processing is not being performed.
        qName - The qualified name (with prefix), or the empty string if qualified names are not available.
        attributes - The attributes attached to the element. If there are no attributes, it shall be an empty Attributes object.
        Throws:
        org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
