Argh! Nasty, nasty HTML! 8^)

Perhaps you could try LUXMLInputStream:

http://dev.alt.textdrive.com/file/lu/LUXMLInputStream.lua

Usage example:

local aContent = "<a href=\"http://www.example.com\"; alt=\"> example\"> 
example </a>"
local anInputStream = LUXMLInputStream( aContent )

for  aType, aText, aName, someAttributes in anInputStream:iterator() do
        if aType == LUXMLInputStream.Text then
                print( aType, aText )
        elseif someAttributes ~= nil then
                print( aType, aName, someAttributes )
        else
                print( aType, aName )
        end
end

Or if you simply want the textual part:

for aText in anInputStream:iterator( true ) do
        print( aText )
end
