How to list all node of a template

[Tiago Matos]

Hello all!

I have posted a question, which is bothering us for a long time. I am cross-posting it from stackoverflow:

Considering the following parsed template and a loop to its root.nodelist:

text = '{% if true %}{{ "poland" | capitalize }}{% else %}{{ "portugal" | capitalize}}{% endif %}'


template = Liquid::Template.parse(text)


template.root.nodelist.each { |node| p node }

will print only:

Portugal 

(and not Poland)

How could one list all nodes (including Liquid variables, tags, etc) from a template? Especially those inside if/else logic?
