Has anyone hacked Builder::XmlMarkup to dasherize underscore tags by  
default? I know I can use tag!, but I’d like to find a way for it to  
translate underscores to dashes automatically. In other words:

xml.department\_manager do  
"fred  
end

#=\> fred

I tried hacking Builder::XmlBase.method\_missing but got myself all  
twisted up!

Thanks.

Steve

xml.tag! ‘department-manger’, ‘fred’

Right, I know about ‘tag!’ but I was hoping to rig things such that  
XmlMarkup always called ‘dasherize’ on element names.
