Non-text Event child nodes not supported about python-mpegdash

[davemevans]

In case it helps anyone, I solved it as follows in the application code. Note this only considers the BinaryType child type ie urn:scte:scte35:2014:xml+bin for Signal, not SpliceInfoSectionType as we had no need for that.

def __init__(self):
    self.signals = None                                   # Signal
    self.message_data = None                              # xs:string
    self.presentation_time = None                         # xs:unsignedLong
    self.duration = None                                  # xs:unsignedLong
    self.id = None                                        # xs:unsignedInt

def parse(self, xmlnode):
    self.signals = parse_child_nodes(xmlnode, 'Signal', Signal)
    self.message_data = parse_attr_value(xmlnode, 'messageData', str)
    self.presentation_time = parse_attr_value(xmlnode, 'presentationTime', int)
    self.duration = parse_attr_value(xmlnode, 'duration', int)
    self.id = parse_attr_value(xmlnode, 'id', int)

def write(self, xmlnode):
    write_child_node(xmlnode, 'Signal', self.signals)
    write_attr_value(xmlnode, 'messageData', self.message_data)
    write_attr_value(xmlnode, 'presentationTime', self.presentation_time)
    write_attr_value(xmlnode, 'duration', self.duration)
    write_attr_value(xmlnode, 'id', self.id)

class Binary:
    def __init__(self):
        self.binary_value = None
        self.signal_type = None

    def parse(self, xmlnode):
        self.binary_value = parse_node_value(xmlnode, str)
        self.signal_type = parse_attr_value(xmlnode, "signalType", str)

    def write(self, xmlnode):
        write_node_value(xmlnode, self.binary_value)
        write_attr_value(xmlnode, 'signalType', self.signal_type)

class Signal:
    def __init__(self):
        self.xmlns = None
        self.binarys = None

    def parse(self, xmlnode):
        self.xmlns = parse_attr_value(xmlnode, 'xmlns', str)
        self.binarys = parse_child_nodes(xmlnode, 'Binary', XsStringElement)

    def write(self, xmlnode):
        write_attr_value(xmlnode, 'xmlns', self.xmlns)
        write_child_node(xmlnode, 'Binary', self.binarys)

Event.__init__ == __init__
Event.parse = parse
Event.write = write
