Hi David,

Yes. I am sure. The function returns a variable of type string:

for i=0,nglobatts-1 do begin
    HDF_SD_ATTRINFO,sd_id,i,name=n,type=t,count=c,data=d
    if (t eq 'STRING' ) then print,strtrim(n),t,c,d[0,0],FORMAT=FS
else $
    if (t eq 'FLOAT' )  then print,strtrim(n),t,c,d[0,0],FORMAT=FF
else $
    if (t eq 'DOUBLE' ) then print,strtrim(n),t,c,d[0,0],FORMAT=FD
else $
    print,strtrim(n),t,c,d[0,0],FORMAT=FI
endfor

ENVI> help, d
D STRING = '
GROUP = ARCHIVEDMETADATA
GROUPTYPE = MASTERGROUP

The actual string returned is roughly 11000 chars long, which
indicates it holds all the individual tags. When printed, the string
is structures in an XML kind-a structure (Nested meta data format).

Any suggestions?

Cheers,

Jelle.
