. How much time would you estimate it would take to convert your card system to a computerized database? :-)

But why? What benefit would be served? Not everything has to be done in bits & bytes. Sometimes pencil & paper, or post-its, or scribbles on a whiteboard, are the best tools for the job. In this case, having to go into a computer to enter the information probably DECREASES the likelihood that the data will be captured.

This time tracking task is not necessarily a nail for the computer hammer.

[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.
