Tiny XML Builder

Description

A very simple XML builder class. + I wanted something really simple that I could easily extend myself later on if I needed to. + Ironically, in four years since I created and used TinyXml, I never needed to extend it :-) I figured, it may as well work for others in that case, so here it is.

Acknowledgements

A big thanks to Jim Weirich for his great advices on Ruby-talk. + The BlankSlate "mechanism" he describes at: http://onestepback.org/index.cgi/Tech/Ruby/BlankSlate.rdoc and which this library depends upon, is one of the first things I've learnt when started to play with Ruby DSLs.

Features/Problems

• You cannot have XML elements named __id___, _send, method_missing, instance_eval or respond_to as those are NOT undefined (on purpose) by BlankSlate mechanism;
• There are other limitations related to ``implicit receiver'' calls, e.g.:

.Explicit receiver example

puts TinyXml::Builder.new.foo {|f| f.p 'bar'}

will output:

bar

------------

while the following:

.Implicit receiver example

puts TinyXml::Builder.new.foo { p 'bar' }

will output:

"bar"

as "p" method exists in outer scope and does an entirely different thing than what (missing) methods of TinyXml do.

Synopsis

.Example Usage

builder = TinyXml::Builder.new builder.html do |xhtml| xhtml.head do |head| head.title 'Hello World' head.meta :name => :keywords, :content => 'hello, world' head.meta :name => :description, :content => 'hello world sample usage for XML class' end xhtml.body do |body| body.div :id => 'main' do |div_main| div_main.h1 "Hello World" div_main.p "Hello HTML world", "from XML" end end end

puts builder

.Alternate Example Usage

puts TinyXml::Builder.new.html { head { title 'Hello World' meta :name => :keywords, :content => 'hello, world' meta :name => :description, :content => 'hello world sample usage for XML class' }

body { div(:id => 'main') { |div| div.h1 "Hello World" div.p "Hello HTML world", "from XML" } } }

both will output:

Hello World

Hello World

Hello HTML world

from XML
