Hi,
may I ask another question about my new favorite topic? No? Anyway: here
comes. While processing xml, I would like to store the content of a node
in a lua table and retrieve it later. The example is silly, but
demonstrates my problem. Is there a way to have ConTeXt process and
typeset the value in lines 3 and 4? As you can see, it typesets the raw
xml instead of processing it. (I suspect I'm still a bit lost regarding
the difference between xml... and lxml... functions, but I couldn't hit
the right combination here).
Thanks, and all best
Thomas
