Rael Dornfest has released PRAX,
a PHP implementation of RAX, a simple API for accessing
database-like XML.
RAX was conceived by Sean McGrath, and described in
XML.com earlier this year. Dornfest's PHP version is a
port of XML::RAX,
a Perl implementation by Robert Hanson.
PRAX can read recordsets from either XML in a string or a
file. It requires the XML module enabled in PHP.
