Subject: [NTG-context] Re: xmlpos values doubled
Date: Tue, 21 Nov 2023 20:30:43 -0500 [thread overview]
Message-ID: <8CFD1B9D-27E6-4D80-80C8-B9C6DBDEA954@gmail.com> (raw)
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
