<?xml version="1.0"?> <connectiondefs xmlns="http://www.dabodev.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.dabodev.com conn.xsd" xsi:noNamespaceSchemaLocation = "http://dabodev.com/schema/conn.xsd"><connection dbtype="MySQL"> <name>Demo</name> <host>dabodev.com</host> <database>webtest</database> <user>webuser</user> <password>KEDO74U81O5DM5CD0AX01L13</password> <port>3306</port> </connection> </connectiondefs>
