Database creating from XML file

Hello PHP users, I've recently tried to find info about creating databases from XML files and didn't find anything. Since there is no php.XML I'm posting it in the general section. Does anyone know where I can find PHP source code that will parse an XML file and generate SQL queries that would create tables based on the structure described on the XML? Something like: xml = " <Database name='db1'> <Table name='Table1'> <Attribute name='foo1' type='int4' /> </Table> </Database> "; and some function func(xml) would return a set of SQL queries that would create that database in a particular DB (say PostgreSQL or MySQL). Anything similar would help already. Thanks in advance, Bernardo de Barros Franco
