Printing authconfig output as XML

Just a quick followup to my post about bringing Openfiler up-to-date.  Here is a script which takes the output of 'authconfig --test' and formats it as XML.

#!/bin/bash
authconfig $* --test | sed 's/ is \| are /=/
s/ = /=/
s/ by default\|always \| (.*)//
y/ +/__/
s/^_/ /
s/_or_.*=/=/
/="/! s/=/="/
/"$/! s/$/"/
/.=/! d
s/=/\#/' | awk -- '
BEGIN {
   FS="#";
   printf("<?xml version=\"1.0\"?>\n");
   printf("<authconfig>\n");
   printf("  <globals>\n");
   SETTING="false";
}
!/^ / {
   if (NR>1) {
   if (SETTING=="true")
      { printf("/>\n");
        printf("    </key>\n") }
   else
      { printf("/>\n") }
   }
   SETTING="false";
   printf("    <key name=\"%s\" value=%s",$1,$2)
}
/^ / {
   if (SETTING=="false")
      { printf(">\n");
        printf("      <settings")
   }
   printf("%s=%s",$1,$2);
   SETTING="true";
}
END {
   if (SETTING=="true")
      { printf("/>\n");
        printf("    </key>\n") }
   else
      { printf("/>\n") }
   printf("  </globals>\n");
   printf("</authconfig>\n");
}'
