I am joining @christhekeele here – f.ex. using :xmerl is maddening because it has a nice low-level streaming interface (among others!) because on the one hand, 95% of the code is exactly the same… but the other 5% vary every frakkin time. This really makes it very difficult to extract out libraries. I entertained the idea but ultimately concluded it would add too little value for what would basically be just one instance of a SAX parser with the ability to pass “callbacks” to it… something everyone can roll in literal one hour maximum.
