* @function all_tags_from_xml()

*
* @param $xml (object): The an XML object containing the relevant children
* obtained from the XML. Could be obtained by XML->children('oml', true)
* or something similar, to get all childeren in the OML namespace.
* @param $configuration (2d string array): an array configuring which fields to be
* included in the return value. $configuration can contain 4 sub arrays, 'array',
* 'csv', 'plain' and 'string'. Putting a field in one of these sub arrays, deter-
* mines
* @param $return_array (string array): The base array to add tags to. Usually, when
* some fields are already set, these can be joined with the fields to
* be set within this function.
*
* @return (MULTIPLE VALUES array): asociative array containing all selected tag-names
* as keys and all tag content as the values.
