xpmmetaget
This queries the default metadata from messages that are produced by
xpmId
.
xpmmetaget ?-rw | -ro | -all? xpmId ?key?
-rw
and -ro
restrict the list to the read-write, or modifiable, and read-only key
lists.
If you do not specify a key
value, then
the available metadata keys are returned.
If you specify a key
value, then the
metadata that is associated with that key returns.
Manipulating data
You can manipulate metadata in the Translation tool, so that an xlate can configure HTTP headers/URL and modify DRIVERCTL during xlate.
This, and other metadata fields, is accessed in xlate using the xpmmetaget and xpmmetaset commands.
Example:
set udata [xpmmetaget $xlateId USERDATA]
