I have some kind of XML conversion gateway, and it accepts XML in one format and gives it to another from sources that I probably would not trust. Now these transformations can be either trivial, as in changing the pair of attrs here and there, or quite complex when I need to parse all the input and build the output from scratch. So basically I have two problems:
XML parsing. It should be fast (preferably) and work without blowing up a table of atoms (I look at you, xmerl), since the sources are not so reliable.
Easy access to deeply nested elements to get the information needed for recovery.
Although there are several options for parsing XML, such as fast_xmland libraries erlsom, they generate structures that are pretty hard to access because they are not comparable to xmerl_xpathand so far the only reasonable way I've found that they are deeply nested data.
So, the question is, is there a way to achieve these goals without spending a lot of time creating your own solution?
PS Jokes aside? Trying to close this question? I am not asking which library to use out of the 100 available, I am asking how to solve a problem that can occur for most people who choose to use Erlang to process XML.
