lxml - a sane Python wrapper for libxml
%center
Martijn Faassen, Infrae
faassen@infrae.com
%page
The C library libxml has huge benefits
Standards-compliant XML support
full-featured
actively maintained by XML exports
fast. fast! FAST!
%page
Features of libxml
Parsing
Tree based (DOM-ish) XML structure
XPath support
XSLT support (libxslt)
Relax NG (schema) support
And more
%page
But libxml already has Python bindings!
very low level and C-ish (not Pythonic)
underdocumented. huge, you get lost in them
works with UTF-8, not native Python unicode
can cause segfaults from Python
have to do manual memory management!
%page
lxml is a new Python binding for libxml
Aims (read: TODOS)
Pythonic API
Documented
Use Python unicode strings in API
Safe (no segfaults)
No manual memory management!
%page
Tradeoffs
Slower because of better wrapping.
But libxml is so fast this likely doesn't matter much.
Not all features of libxml exposed (unless you help)
%page
What is there now - Proof of concept
Automatic destruction of documents (refcounted)
Start of ElementTree style API for tree
%page
Future
Fix bugs, add features
Moving into svn repository on codespeak.net
Help!
