This is a slighly modified version of the XMLUtilityNode from merb.devjavu.com/projects/merb/ticket/95 (has.sox@gmail.com)
John Nunemaker: It’s mainly just adding vowels, as I ht cd wth n vwls :) This represents the hard part of the work, all I did was change the underlying parser.
Simple xs:date Regexp.
Simple xs:dateTime Regexp.
Simple xs:time Regexp.

Converts the node into a readable HTML node.
@return <String> The HTML node in text form.
# File lib/nori/xml_utility_node.rb, line 217 def to_html attributes.merge!(:type => @type ) if @type "<#{name}#{attributes.to_xml_attributes}>#{@nil_element ? '' : inner_html}</#{name}>" end
Typecasts a value based upon its type. For instance, if node has type == “integer”, {{[node.typecast_value(“12”) #=> 12]}}
@param value<String> The value that is being typecast.
@details [:type options]
"integer":: converts +value+ to an integer with #to_i "boolean":: checks whether +value+, after removing spaces, is the literal "true" "datetime":: Parses +value+ using Time.parse, and returns a UTC Time "date":: Parses +value+ using Date.parse
@return <Integer, TrueClass, FalseClass, Time, Date, Object>
The result of typecasting +value+.
@note
If +self+ does not have a "type" key, or if it's not one of the options specified above, the raw +value+ will be returned.
# File lib/nori/xml_utility_node.rb, line 181 def typecast_value(value) return value unless @type proc = self.class.typecasts[@type] proc.nil? ? value : proc.call(value) end
