This package provides an implementation of a query language for Python. The query language is based on Python's generator expression. A query in this language looks like this:

>>> from xotl.ql import these, parent

>>> query = these(child 
...               for parent in this
...               if parent.children & parent.age > 32
...               for child in parent.children
...               if child.age < 6)

The resultant query is an object that "describes" at the syntactical level the query expression above.

Full documentation kept at Read the doc.
