If polling a url n times and breaking if response is 'completed', is the best to approach to use try catch and error() to get around immutability? I need the full response on complete so I redo the last http get. It is not a biggie requesting twice. Adam

What hooks does BaseX provide for XProc? Where can I find examples of BaseX use in an XProc pipeline?

The hof:until function may help you [1]. Don’t hesitate to supply us with a minimized code snippet.
In general, it’s almost always a good advice not to use try/catch unless you need to catch real errors.

Hi Christian - many thanks for the pointer. hof:until works well and without a double http:send-request.
let $pollingResult := hof:until(function($result) {$result?3//status/text()= 'done'},function ($input){[$input?1 + 1,prof:sleep(5000),http:send-request($requestPolling)]}, [1,0,http:send-request($requestPolling)])

Slight improvement let $polling := hof:until(function($result) {$result?3//status/text()= 'done' or $result?1 > 10},function ($input){[$input?1 + 1,prof:sleep(5000),http:send-request($requestPolling)]}, [1,0,http:send-request($requestPolling)])
