Would it be possible to extend happymapper to accept a function for transforming element names into tagnames?

[deiga]

I dislike having to type too much and transformation form snake_case to PascalCase just doesn't seem too sensible (element :mime_type, String, :tag => 'MimeType'). Would it be possible to just add an attribute that takes a set of params (ie. what case to transform into) or a block/proc to handle the transformation?

Examples:

• element :mime_type, String, :tag_format => :pascal
• element :mime_type, String, :tag => Proc.new { |name| return "%f %s" % [5, name] }

Perhaps a simple solution is to allow automatic transformation in the opposite direction:

element String, tag: 'MimeType'

This would automatically underscore-ize the tag name, similar to the existing HappyMapper.parse method.
