Hi list,
I came across this old thread as I was trying to use \xmlpos{#1} to
"dynamically" create references such as \item[mystep:\xmlpos{#1}] to be
referenced when other elements of this node are parsed at a later point.
In fact, it seems that \xmlpos{#1} returns duplicate values. This might indeed
be the intended meaning of \xmlpos{#1} as it seems related to the XML query
foo/bar/index() which only looks up the position in the parent node. (I noticed
that if I run this repeatedly, I get somehow different values from times to
times. I can't say why.)
Anyways, I was wondering if there is a TeX command to access the absolute
position of an element in the tree? Similar to foo/bar[rootposition()] (or
foo/bar[order()]? – Can't make sense of the entry in the XML manual.)
Thank you for your help!
Benjamin
