[lxml-dev] Explicit type checking and zope.security

[Christian Zagrodnick]

Hi,

lxml does quite some explicit type checking. For instance:

    object_path.addattr(root, value)

gives me an error if root is security proxied:

      File "objectpath.pxi", line 74, in lxml.objectify.ObjectPath.addattr
    TypeError: Argument 'root' has incorrect type (expected 
lxml.etree._Element, got zope.security._proxy._Proxy)


Is this explicit checking really necessary? It's quite annoying to have 
to unwrap everything (and eventually check manually for security) 
before putting it into lxml's hands.


Any other ideas?

Regards,
