Using the ruby UI wrapper (for DIALOG), such command could take the
query = TextMate::UI.request_string(:prompt => "XPath Query:")
TextMate.exit_discard if query.to_s.empty?
# output HTML based on stdin and query…
You can mix this with the suggestion by Hans-Jörg, i.e. let the
generated HTML include a text field prepopulated with the query string,
allowing the user to change the query.
If so, you may want to allow an initial empty query string, for that,
change ‘query.to_s.empty?’ → ‘query.nil?’ in the above. This
will still allow the user to abort the command (and never see the HTML
output window) via the Cancel button (or ⌘,) but if they just press
return, the window will appear.
