XML and Lua/Ctx

Hello,

I've read that when Ctx is to process a XML file, the whole XML tree is loaded first and processed as wanted.

I'd need to process a XML file which represents an Excel workbook saved as .xml.

When working in pure Lua, I'm using Expat library (http://matthewwild.co.uk/projects/luaexpat/index.html) which allow to create a parser with callbacks (e.g. StartElement(), StopElement(), CharacterData()...).

It processes the .xml file on-the-go.

However, this solution cannot be used with Ctx as it causes Ctx to crash.

How to access a XML file loaded and parsed from within Ctx via Lua?

I attach a simple Excel XML (for those who are familiar with Excel and don't refuse using it).

As an example, I'd need process the attached .xml into a simple Lua table:

----
-- return -- Lua table as a result
{ workbooks =
   { [1] = { name = "1",
             -- No more info is necessary so far,
             -- I just need to see the way how to access XML elements
           },
     [2] = { name = "Imp",
           },
     [3] = { name = "Exp",
           },
     [4] = { name = "<Template>",
           },
   }
}
----

Could anyone experienced kindly present a way how to get such table from the attached Excel XML file?

TIA.

Best regards,

Lukas
