searching in nodes

searching in nodes

[Hans van der Meer]

[-- Attachment #1.1: Type: text/plain, Size: 595 bytes --]

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?

you can use lua in your path expressions

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

and such
