Extract all HTML Objects from a Web Page

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

Download Chilkat Ruby Library

require 'chilkat'

mht = Chilkat::CkMht.new()

success = mht.UnlockComponent("30-day trial")
if (success != true)
    print "Mht component unlock failed" + "\n"
    exit
end

# Download a URL into an in-memory MHT web archive contained
# in a string variable:

mhtDoc = mht.getMHT("http://www.gopackaging.com/")
# On failure, the mhtDoc will be a zero-length string.
# Check the LastErrorText property for error information.

# Now extract the HTML and embedded objects:
unpackDir = "c:/temp/"
htmlFilename = "gopackaging.html"
partsSubdir = "objects"
# Extract to c:/temp/gopackaging.html.
# images and other embedded objects are placed in
# c:/temp/objects.  Directories are automatically
# created if they don't already exist.
success = mht.UnpackMHTString(mhtDoc,unpackDir,htmlFilename,partsSubdir)
if (success != true)
    print mht.lastErrorText() + "\n"
else
    print "Unpacked!" + "\n"
end
