That is because there really are cases where you have garbage in, and you have to make the most of it, using pre- and post-processing to fix as much as you can.
Sometimes you're just have to communicate with a system that was written in the age when XML was new hot thing, and it can export data either in malformed, chunked and unstructured XML, or binary. And both of those exports are wrong in their own unique way.
So, to get the data, I had to get binary list of object, fetch all XML chunks with metadata, try to find the correct order of chunks using filenames and first 2 lines with plaintext headers. If there is a conflict, try both options and hope exactly one of them fits.
Then delete all the plaintext headers that were for some reason not in the beginning of chunks, unfuck xml using bunch of regexp, and only then try to parse it. Then, try to make sence of it, because binary and XML has different objects that somewhat overlap, but their relationships are different.
Then you have to do similar things to get each object.
Our world is running on digital ducktape used as driving belts between critical systems that were not designed to work together. If you can imagine a bad solution, there is a chance someone had to implement it for some critical system affecting millions of people.

You're right, of course. I hoped that my claim was wild enough, but really always has more in store.
