Python KML library

=========
PyKML
=========
PyKML is a Python package for parsing and authoring KML documents. It is based
on the lxml.objectify API (http://codespeak.net/lxml/objectify.html) which
provides Pythonic access to XML documents.

Dependencies

* lxml

Installation
------------
PyKML can be installed from the Python Package Index, using either easy_install
or pip:

$ sudo easy_install pykml

or

$ sudo pip install pykml

Usage
------

KML documents can be constructed by using element factory objects. The
following example uses two factory objects, corresponding to the OGC KML and
ATOM namespaces:

>>> from pykml.kml_ogc.factory import KML_ElementMaker as KML
>>> from pykml.kml_ogc.factory import ATOM_ElementMaker as ATOM
>>> doc = KML.kml(
... KML.Document(
... ATOM.author(
... ATOM.name("J. K. Rowling")
... ),
... ATOM.link(href="http://www.harrypotter.com"),
... KML.Placemark(
... KML.name("Hogwarts"),
... KML.Point(
... KML.coordinates("1,1")
... )
... )
... )
... )

Constructed documents can be converted to a string respresentation:

>>> from lxml import etree
>>> etree.tostring(doc)

and can be validated against the official KML XML Schema:

>>> from pykml.kml_ogc import schema
>>> print schema.validate(doc)

Existing KML documents can also be parsed:

>>> import urllib2
>>> from pykml.kml_ogc.parser import parse
>>> url = 'http://code.google.com/apis/kml/documentation/KML_Samples.kml'
>>> fileobject = urllib2.urlopen(url)
>>> tree = parse(fileobject, validate=True)

Documents that make use of the Google Extension namespace elements can be
created by importing the appropriate factory objects:

>>> from pykml.kml_gx import schema
>>> from pykml.kml_gx.factory import KML_ElementMaker as K
>>> from pykml.kml_gx.factory import ATOM_ElementMaker as ATOM
>>> from pykml.kml_gx.factory import GX_ElementMaker as GX
>>> doc = K.kml(
... GX.Tour(
... GX.Playlist(
... GX.SoundCue(
... K.href("http://dev.keyhole.com/codesite/cntowerfacts.mp3")
... ),
... GX.Wait(
... GX.duration(10)
... ),
... GX.FlyTo(
... GX.duration(5),
... GX.flyToMode("bounce"),
... K.LookAt(
... K.longitude(-79.387),
... K.latitude(43.643),
... K.altitude(0),
... K.heading(-172.3),
... K.tilt(10),
... K.range(1200),
... K.altitudeMode("relativeToGround"),
... )
... )
... )
... )
... )
>>> print schema.validate(doc)
