You probably meant something like
names = []
XPath.each ( doc, “//lm:name”) { |element| names << element.text }

In your code the block does nothing apart from output the text - the
return value is just the collection iterated over.

invisibility = XPath.first( doc, “//lm:landmark” )
names = XPath.each( doc, “//lm:name”) { |element| puts element.text }

puts names

it’s better posting on the mailing list because if someone else has a
similar problem, they may google it and find it.
