Re^5: Building SQL Query on the fly

If you provide a snippet of real data from the table, and a snippet of what you want the XML to look like, I expect others will have no trouble pointing you in the right direction. But you might very well figure it out on your own first.

In the meantime, I'll just say that your loop over the fetched database rows will be building (array elements within) a hash structure, and the structure will be passed to the XMLout method of your XML::Simple object. I'm not sure, but your structure loading loop might be something like this:

my %xml_hash = ( rootnode => [] ); # top XML node has an empty array_r
+ef as value

while ( my $row = $sth->fetchrow_hashref ) {
    push @{$xml_hash{rootnode}}, $row;
}

print $xmlobj->XMLout( \%xml_hash );

I'm probably missing some important details there, and I'm sorry that the XML::Simple docs are so huge. Good luck, and good night.

Thanks! The following seems to work. I appreciate all the help! `$sth->execute(@bind); my %xml_hash = ( dataset => [ ] ); while (my $row = $sth->fetchrow_hashref ){ push @{$xml_hash{dataset}}, $row; } my $cgi = CGI->new; print $cgi->header('text/xml'); my $testxml = XMLout( \%xml_hash, NoAttr => 1, RootName => data +set, ); print $testxml; $sth->finish();` [download]	[reply] [d/l]

$sth->execute(@bind);
        my %xml_hash = ( dataset => [ ] );

        while (my $row = $sth->fetchrow_hashref ){
                push @{$xml_hash{dataset}}, $row;
        }

        my $cgi = CGI->new;
        print $cgi->header('text/xml');
       my $testxml = XMLout( \%xml_hash, NoAttr => 1, RootName => data
+set, );
        print $testxml;
        $sth->finish();
