The `parse_programming_language` function extracts OPTION elements without validation. If an OPTION element is missing the `key` or `value` attribute, the xpath will return nil, which will then be used in `Map.new(&{&1.key, &1.value})`. This could create map entries with nil keys or values. Consider adding filtering to skip OPTION elements with missing required attributes, or document the expected XML structure more explicitly.
