i recently needed to deal with a ~4G xml file.. i tried a parser but after waiting thirty minutes for it to load i decided to parse out the bits i needed manually with a bash script knowing my needs i could easily account for all possible muck ups and avoid the instances where ambiguity could play a part i was then able to use the bits i pulled out of the ~4G file, now 16M, in the parser with all of its assurances sure, edge cases justify using a tried and true library for generics, but there are also edge cases that justify mocking up your own naive implementation.. if only, like in my case, to make the dada usable in such a library
