magictree

magictree is a Python module to easily create ElementTree with automatic Element factories.

Developer comments

Creating tree structures like those used for HTML and XML should be dead easy. The xml.etree.ElementTree library goes quite far in creating a simple to use library for creating and modifying such structures. I'd like to go a step further, building on top of ElementTree:

from magictree import html, head, title, body, h1, p
doc = html(
 head(
 title('Chapter 1: Greeting')),
 body(
 h1('Chapter 1: Greeting'),
 p('Hello, world!')))

from xml.etree import ElementTree as et
et.dump(doc)

Results in this: (added some whitespace for formatting)

< html >
 < head >
 < title >Chapter 1: Greeting< /title >
 < /head >
 < body >
 < h1 >Chapter 1: Greeting< /h1 >
 < p >Hello, world!< /p >
 < /body >
< /html >

This works by replacing this module with a wrapper object in sys.modules that creates factory functions for elements based on their name.
