Hello,
I'm having problem using LuaXml library with Ctx, both using Lua ver. 5.2.
LuaXml works fine with Lua standalone programs/scripts;
but something weird occurs when used from within Ctx (e.g. a .xml file
can be read successfully from standalone Lua with LuaXml lib; but the
same code doesn't give the desired result when used in combination with
Ctx; a problem might be version mismatch - I'm still using both Lua 5.1
and 5.2 including 3rd party modules in my scripts - but my latest tests
with Ctx & LuaXml should have avoid this; or namespace mismatch...?).
I don't know (and as we have quite some code on-board I don't care too
much either about clashes in namespaces).
Anyway, does native Ctx XML API (has it its own namespace, like
'context.xml'?) provide a function to load a .xml file and to return its
XML tree as a table, with nodes (as a table with node attributes as
table members) in a proper sequence... something like LuaXml's
'xml.load("file.xml")' does?
I assume that you also want the content of elements, not just the
attributes.
Or how to achieve this in a best way under Ctx: XML file -> Lua table/tree?
It all depends on what kin dof table you want (if the content is an
indexed table and attributes keys then you have the problem that the
element cannot be a key too as it can clash) .. anyway, it's no big deal
to provide a stupid table, so I can provide something because after all
the loaded xml file is a table already.
local x = xml.load("file.xml")
local t = xml.totable(x)
where x is an index/hash mix plus _tag, _type and _namespace fields as
well (after all I assume that you need to know that too).
(btw, I bet that you can do what you want with the existing
functionality as well, so there is not much benefit in such a table)
Probably in the next upload,
Hans
