Great patch! You already knew that... ;)

There's one scenario that should not stored in the second level cache
using the caching framework:
When the XML parser fails with an error message (e.g. "Line x: no
element found") that result can be in the runtime cache but should not
enter the database cache. Checking whether the result of
xml2arrayProcess() is an array should be enough here...

Besides that +1 on reading and testing
