Re^2: accessing root tags when using XML::Twig and twig

If I use a start_tag_handler for the root element, then I can't have "roots" that are a subset of the whole document.

If I set the "roots" within the first callback, what happens to the printout? I have a partial open going on and it hasn't started printing outside of roots yet. Whatever happens, will it be well-behaved?

Couldn't you do two passes against the file? First create a twig with the start_tag_handler to get whatever it is you need. Then use that information to create a second twig for the actual processing. Would that work or am I missing something? As mirod mentions some sample code and data might help clear things up.	[reply]

Yes, that is an option, now that I know how to quit once I find what was needed. Someone said that `die` from a handler will do the trick, presumably without leaving the module in a funny state.	[reply] [d/l]

What did you try? I find it easier to get some code to work than to answer questions like these ;--(	[reply]
