<br>
I would like to put a string into a box and then work on the node list.<br>
If the string were available on the TeX side I would<br>
<br>
\setbox0\hbox{...}<br>
<br>
and the use it on the Lua side<br>
<br>
tex.box[0]<br>
<br>
But what should I do if the string is generated on the Lua side and<br>
thus no available on the TeX side? Is it possible to call the TeX<br>
scanner to read this string?<br>
<br>
