(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.

because {} is not {*} but basically self

(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?

why do you use xmlindex in this case you could use \xmlfirst{#1} or \xmlfilter{#1}{[position()=1]} (I will probably rewrite xmlindex as it's a leftover) ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
