you can use lua in your path expressions

[hvhm.findmypattern(text(),'whatever')]

and such

[NTG-context] searching in nodes

[Hans van der Meer]

In a Lua function called from within an \startxmlsetups..\stopxmlsetups code 
block I would like to search through the current node and all below.
Using string.match("to-be-searched”,”pattern”).
The Lua function being called through 
\def\findmypattern#1#2{\ctxlua{tex.print(hvdm.findmypattern("#1","#2",))}

But I do not seem to get the node contents in the first argument #1. Using 
\xmlverbatim{#1} fails with Lua error "hexadecimal digit expected near '"\xm’”. 
\xmlflushpure{#1} fails with Lua error "invalid escape sequence near …”

Any help?
