Nick Coghlan added the comment: Since parsers don't support changing the target after creation, I think it makes sense to deprecate passing in a parser *instance*, and instead require passing in a callback that accepts the target to use and *returns* an appropriate parser object. The "parser can only use the default TreeBuilder as a target." line in the iterparse docs is a sign that this is a more appropriate API - if iterparse needs a particular kind of target, the API should be designed so iterparse *provides* that target instead of saying "please don't use a custom target type".
However, I don't think it makes sense to provide such a callback based API until it is actually possible to implement the streaming event API using a custom target object with XMLParser. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17741> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
