Given this document:

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE datasources SYSTEM "datasources.dtd">
<datasources>
	<datasource>
		<name>a name</name>
		<host>localhost</host>
		<port>3306</port>
		<database>database1</database>
		<username>someusername</username>
		<password>somepassword</password>
	</datasource>
	<datasource>
		<name>another name</name>
		<host>localhost</host>
		<port>3306</port>
		<database>database2</database>
		<username>itsusername</username>
		<password>andthepassword</password>
	</datasource>
</datasources>

I would do something like this:

  d = {}
  for event, element in ET.iterparse("thefile.xml"):
      if element.tag == "datasource":
          d[element.find("name")] = tuple([ el.text for el in element ])
