Parameters

• name (Tuple[Optional[str], str]) –

• qname (Any) –

• attrs (Dict) –

endElementNS(name, qname)

End element notification receiver.

The receiver will flush any previous active element and set the next element to be flushed.

Converts name and attribute keys to fully qualified tags to respect the main parser api, eg (foo, bar) -> {foo}bar

Parameters

• name (Tuple) –

• qname (Any) –

characters(content)

Proxy for the data notification receiver.

Parameters

content (str) –

startPrefixMapping(prefix, uri)

Start element prefix-URI namespace mapping.
