[ambrus]: (I haven't found an idle event.)
[ambrus]: However, I also looked at the internals, and found two interesting things:
[marto]: stupid xpath question, I have a xpath copied from the browser, is the * wildcard supposed to work for IDs? e.g. '//*[@id="*"]/ div/div/header/p/a '?
[ambrus]: The main loop for unixish systems is in https://metacpan. org/source/ KARASIK/Prima-1. 49/unix/apc_app.c. It is a hand-rolled select loop, but also always spins at least once every 0.2 seconds for some reason.
[ambrus]: marto: no, not that way. if you just want to test for an existing id attribute, then write *[@id] , or you can match a regexp to the value of that attribute like *[@id=~/something/ ]
[marto]: ambrus, thanks I ended up going with '//*[starts- with(@id, "thread_")]...
[ambrus]: Sometimes it's easier to just match elements in ways other than xpath, like directly with perl code.
