sfeed_xmlenc — get
text-encoding from XML
sfeed_xmlenc reads XML data from stdin and
writes the found text-encoding to stdout. It converts characters in the
encoding-name to lowercase and strips characters which are not allowed in an
encoding-name.
The sfeed_xmlenc utility exits 0 on
success, and >0 if an error occurs.
