[chef] Using the value from an XML file in a template variable

[Greg Barker < >]

I've got an xml file that is generated during a chef run by a third party utility, and I want to retrieve a value from this xml file and use it in a template variable. How should I go about doing that?

I was thinking maybe something like this, but it didn't work. other_thing ends up being a blank value:

template "/some/file.xml" do

    source "source_file.xml.erb

    variables(

        :some_thing = node["some"]["thing"],

        :other_thing = lazy {

            require "rexml/document"
            REXML::XPath.first(REXML::Document.new(File.new("#{node[:some][:dir]}/config.xml")), '//id').text

        }
    )

end
