Hi folks,

I’m not sure if I’m grokking how to use Markaby correctly. I’m trying  
to render some external Markaby code as follows but get the  
ArgumentError at the end:

What would be the correct way to render the given Markaby code  
fragment? The error is bubbling up from XmlBuilder

I would have done like this:

mab = Markaby::Builder.new  
mab.instance\_eval template  
mab.to\_s

The error is in the template.

h1 “Header” do; … end

That’s invalid.

Try:

html do  
h1 “Header”  
p “Paragraph”  
end

Or, if the paragraph does really belong in the header:

html do  
h1 { “Header” + p(“Paragraph”) }  
end

The last one requires Markaby 0.4.65 or greater[1]. May good fortune  
swirl  
around in your Thermos forevermore.

[1] gem install markaby --source [code.whytheluckystiff.net](http://code.whytheluckystiff.net)

That produces the same error (In digging around in the code it  
Markaby::Template does that in the render method)
