(1) How does one retrieve an attribute from an element collected with \xmlindex{node{lpath}{n}? (2) I don't understand in xml:test \xmlcount{#1}{} giving 1 for an answer, whereas \xmlcount{#1}{*} and \xmlcount{#1}{/abc} yield 2 as is expected. (3) With the code below \xmlindex starts looping on an empty lpath, whereas like \xmltext{} react without problem. Problem is showed by \xmlindex, \xmlfirst, \xmllast, \xmlall, \xmlconcat Behaviour is not shown by \xmltext{node}{}, \xmlstripped, \xmlstrip Is this a bug in \xmlindex's underlying lua? !
