Hello,
Here is a implementation of David Sklar's BadgerFish [1] convention
for translating an XML document into a Lua table:
http://dev.alt.textdrive.com/browser/HTTP/XML.lua
1. Element names become table keys.
2. Text content of elements goes in the '$' key of a table.
<alice>bob</alice>
becomes
{ alice = { [ '$' ] = 'bob' } }
3. Nested elements become nested tables.
<alice><bob>charlie</bob><david>edgar</david></alice>
becomes
{ alice = { bob = { [ '$' ] = 'charlie' }, david = { [ '$' ] =
'edgar' } } }
4. Multiple elements at the same level become list elements.
<alice><bob>charlie</bob><bob>david</bob></alice>
becomes
{ alice = { bob = { { [ '$' ] = 'charlie' }, { [ '$' ] =
'david' } } } }
5. Attributes go in keys whose names begin with '@'.
<alice charlie="david">bob</alice>
becomes
{ alice: { [ '$' ] = 'bob', [ '@charlie' ] = 'david' } }
Usage example:
local XML = require( 'XML' )
local aContent = io.open( 'atom.xml', 'rb' ):read( '*a' )
local anXML = XML( aContent )
print( anXML.feed[ '@xml:base' ] )
print( anXML.feed.title[ '$' ] )
print( anXML.feed.entry[ 1 ].id[ '$' ] )
for anIndex, anItem in ipairs( anXML.feed.entry ) do
print( anIndex, anItem.title[ '$' ] )
end
Cheers,
PA.
