This is an example script on how to do XSLT transformations in Python 2.6 through the Gnome libxml XML C parser and toolkit. The relative fast C library is available on multiple platforms but you will also need Python bindings for libxml2 and libxslt. There is a handy libxml2 and libxslt Python bindings installer for Windows which also includes the C libraries in DLL form.

This is a Python example script for importing GeoNetwork Metadata Exchange Format 1.1 (MEF) archives to GeoNetwork 2.4.2's mef.import service. The mef.import service requires a multipart/form-data POST through a modified MultipartPostHandler.py library which now supports Unicode (urllib2). It has been tested in Windows XP and Python 2.6.

Attached is an example XSLT1 script to transform a WMS GetCapabilities 1.1.1 response to a CSW Insert transaction. The script is based on deegree's wms2iso19119.xsl (http://www.deegree.org/).
Note that currently it only supports WMS version 1.1.1 (<WMT_MS_Capabilities>) responses because it chokes on 1.3.0 (<WMS_Capabilities>) responses.

Following is a presentation on XML Extract-Transform-Load (ETL) we did at the Geoscience Data Preservation Techniques Workshop, Indiana Geological Survey, Bloomington, IN on July 2009.

Although this presentation was geared towards National Geological and Geophysical Data Preservation Program (NGGDPP) metadata, the same tools can be used for other ETL needs.
