Subject: Ruby Data Structure Query Abstractions/Patterns

Hi all,

I've written a small ruby application that uses YAML and the
associated hash/array Ruby structure.

I am now looking to do some query-like actions on the basic ruby data
structure. I'm wondering if there are any packages of
query-abstractions that make sense for Ruby in a generalized sort-of
way. E.g. XPath and XQuery for XML, SQL for RDMS, etc.

Currently I've written my structure-parsing code with a few of my
cases, and I'm starting to refactor with blocks and lambdas in order
to keep duplication low and offer an easily configurable higher-level
of abstraction. Now the code is starting to pressure me to create a
simple query language. Maybe I should go to a ruby db or sqlite, but I
expect I ultimately only need the most basic functionality.

Any suggestions or recommendations?

Thanks,
Nick
