Subject: Re: Xml filtering in Lua
Date: Wed, 16 Nov 2022 20:56:00 +0100	[thread overview]
Message-ID: <4902918e-d6e1-47a7-6d22-0067262a5714@fastwebnet.it> (raw)
In-Reply-To: <e437223e-14ae-12ec-57ca-9c0003b37765@fastwebnet.it>

This works:

local metadata = xml.filter (t, '../../topics/topic[@t:id=="' .. ch_id 
.. '"]')

also this:

local lpath = string.format('../../topics/topic[@t:id=="%s"]', ch_id)

local metadata = xml.filter (t, lpath)


It looks like xml.filter supports only 2 arguments (see lxml-tex.lua), 
and so it doesn't let you use string formatting patterns like the 
"context" command does.

You can write:

context('the value of @t:id is "%s"', ch_id)

but you can't write:

xml.filter (t, '../../topics/topic[@t:id=="%s"]', ch_id)


Best wishes,

Massi
