* Input Array =
* array('children' => array(
* 'child' => array(
* array('name' => 'Wendy Darling'),
* array('name' => 'John Darling'),
* array('name' => 'Michael Darling')
* )
* ))

* Output XML =
* <children>
* <child><name>Wendy Darling</name></child>
* <child><name>John Darling</name></child>
* <child><name>Michael Darling</name></child>
* </children>
