SXPath

XPath engine in Scheme. For usage and examples, please refer to http://www196.pair.com/lisovsky/query/ .

The code in the Askemos sources has been modified to become more data model agnostic and more efficient. Besides the Askemos data model, it should still work with SXML.

TODO The adantage of the SXPath engine is it's clear source code structure. At the other hand it's too straight it does eager evaluation and lot of superflous calls and eventually violates document order (see here).

XLink

See http://modis.ispras.ru/Lizorkin/ for XLink extensions to SXPath.

Please Note

• These are not yet integrated with the main ball code.
• The traverse:: axis corresponds roughly to DSSSLfetch.
