## GET_SOURCE_URL_LIST

[Next Routine] [List of Routines]

     FUNCTION: GET_SOURCE_URL_LIST
       url_out=get_source_url_list(url_in, xmldir, xmlfile)

     PURPOSE:
       Gets URLs of data files from the metadata database.

     KEYWORDS:
       url_in = Query in the OpenSearch format
       xmldir = Directory where XML file will be downloaded to.
       xmlfile = Returned XML file for search result
       url_out = URLs of data files returned by the Metadata databese

     EXAMPLE:
       url_in='http://search.iugonet.org/iugonet/open-search/request?'+$
              'query=nipr_1sec_fmag_syo_20100101_v02.cdf'
       url_out=get_source_url_list(url_in, './', 'tmp.xml')
