Navigational XPath queries on EU proceedings

Geplaatst op 23-08-2010 door Maarten Marx | Uncategorized | | comment image Geen reacties »

Most XPath tutorials and lessons use data-centric XML data files. For instance, the queries on the CIA-Factbook/Mondial database for first year Information Science at UvA.

We created a set of queries on the XML version of the proceedings of the European Parliament in English.

The queries can all be expressed in XPath 1.0. The level is introductory. Students can make try out their queries in an Exist sandbox and immediately see the results. The set of queries is available as a Google form.

Teachers who want to use this form are welcome. If you want to get the results of your students doe the following:

  1. Think up a good unique code XX for your test. Tell it to your students and let them fill it in in the first question
  2. Sent Maarten Marx an email requesting for the answers to the XPath test for code XX.

You obtain the answers as a csv file as soon as possible.

Model answers are also available by request.
