Generate XML from MySQL
Using MySQL and want to use the data stored there elsewhere? Dump XML out of a MySQL database and then transform it with XSLT.
MySQL (http://www.mysql.com) is a popular, nearly ubiquitous, multiplatform database engine, available under both open source and commercial licenses. It is commonly used as a data store for web sites. This hack shows you how to examine a MySQL database, dump its contents as XML, and then use XSLT to transform and refine the result.
