cldbNodes = search(:node, "cldb:true")

回答1:

To summarize from the comments above, search(...) returns an array so you need to get a specific element, usually the first, before you can access node data.

Using the example above, it would be something like:

cldbNodes = search(:node, "cldb:true")

cldb = cldbNodes.first["fqdn"]

file '/tmp/test.txt' do
    content cldb
end
