x =
for (type, hostname, ipaddr, t) in dnsdata:
ncgi.hdf.setValue("Entry.%d.type" % x, type)
ncgi.hdf.setValue("Entry.%d.hostname" % x, hostname)
ncgi.hdf.setValue("Entry.%d.ipaddr" % x, ipaddr)
ncgi.hdf.setValue("Entry.%d.time" % x, t)

Then, in the template:

<form action=>
<?cs each:entry = Entry ?>
<input type=text name="entry.<?cs var:name(entry) ?>.type"
value="<?cs var:html_escape(entry.type) ?>">
<input type=text name="entry.<?cs var:name(entry) ?>.hostname"
value="<?cs var:html_escape(entry.hostname) ?>">
<input type=text name="entry.<?cs var:name(entry) ?>.ipaddr"
value="<?cs var:html_escape(entry.ipaddr) ?>">
<input type=text name="entry.<?cs var:name(entry) ?>.time"
value="<?cs var:html_escape(entry.time) ?>">
<?cs /each ?>
</form>

And then, to read them back:

node = ncgi.hdf.getChild("Query.entry")
dnslist = []
while node != None:
dtype = node.getValue("type", "")
hostname = node.getValue("hostname", "")
ipaddr = node.getValue("ipaddr", "")
t = node.getValue("time", "")
dnslist.append( (dtype, hostname, ipaddr, t) )
node = node.next()

Obviously, you'll probably use different input elements, and you
need to actually validate the results, but that's the basic gist.
