Extract all HTML Objects from a Web Page

See more MHT / HTML Email Examples

Demonstrates how to download a Web page (at a URL) and extract all HTML objects. Eg. images, links, CSS files, JavaScript files, etc. Lua

local chilkat = require("chilkat")

-- This example assumes the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local mht = chilkat.Mht.new()

-- Download a URL into an in-memory MHT web archive contained
-- in a string variable.
-- The following URL is randomly picked and was valid at the time of writing this example:
local mhtDoc = mht:get_mht("https://www.tetonlodge.com/")
if not mht.last_method_success then
    print(mht.last_error_text)
    return
end

-- Extract the HTML and embedded objects:
local unpackDir = "C:/AAWorkarea/mhtTesting/"
local htmlFilename = "lodge.html"
local partsSubdir = "objects"

-- Extract to C:/AAWorkarea/mhtTesting/lodge.html.
-- images and other embedded objects are placed in
-- C:/AAWorkarea/mhtTesting/objects.  Directories are automatically
-- created if they don't already exist.
local success = mht:unpack_mht_string(mhtDoc, unpackDir, htmlFilename, partsSubdir)
if not success then
    print(mht.last_error_text)
else
    print("Unpacked!")
end
