—snap—

“%%HOSTNAME%%” is used as placeholder within the XML to fill in asked results.

$HOSTNAME is assigned the $VAL and used by sed command to replace and create the modified.xml.

To process 2 asks or more you need to run a script for each.

Note, # and ## work from the left end (beginning) of string,

# % and %% work from the right end.

Another example with several ask:
