Well I got a bit carried away with some regular expressions (which you
should never do on a Sunday) and came up with:

2>/dev/null curl http://esw.w3.org/SparqlEndpoints | grep -A6 '^<tr>$'  |
awk '{  i++  ;  if (i==3 ) print $0 " ." ; if (i==1) print "\n<#endpoint"
p++ ">\n" $0 " ;" ; if ( $1 == "<tr>" ) i = 0; }' | sed 's/<td>
<b>/<dct:description> /' | sed 's/<.td><td>/<void:sparqlEndpoint> /' | sed
's/<void.*href="\([^"]*\).*/<void:sparqlEndpoint> <\1> ./' | sed
's/<dct:description>.*">\(.*\)<.a.*/<dct:description> "\1" ;/'
