Log Message:
py-lxml: updated to 4.6.1

4.6.1 (2020-10-18)

Bugs fixed

A vulnerability was discovered in the HTML Cleaner by Yaniv Nizry, which allowed \ 
JavaScript to pass through. The cleaner now removes more sneaky \ 
"style" content.

4.6.0 (2020-10-17)

Features added

lxml.html.InputGetter supports __len__() to count the number of input fields. \ 
Patch by Aidan Woolley.
lxml.html.InputGetter has a new .items() method to ease processing all input fields.
lxml.html.InputGetter.keys() now returns the field names in document order.
The API documentation is now generated using sphinx-apidoc. Patch by Chris Mayo.

Bugs fixed

C14N 2.0 serialisation failed for unprefixed attributes when a default namespace \ 
was defined.
TreeBuilder.close() raised AssertionError in some error cases where it should \ 
have raised XMLSyntaxError. It now raises a combined exception to keep up \ 
backwards compatibility, while switching to XMLSyntaxError as an interface.
