2 - Bag from/to source

As we have seen in the previous chapter, a Bag is a completely dynamic structure. A Bag has a polymorphic interaction with many complex data sources, so it's possible to fill it passing

• A string representing an XML section
• A file path of an XML file
• An URI of a remore XML file
• A file path of a directory on local disk
• A pickle file
• A Bag

fromlocal= Bag('%s/test_files/standardxml.xml' %current)
fromurl= Bag('http://www.plone.org')
fromdirectory= Bag('%s/test_files' %current)

stringxml='<?xml version="1.02" encoding="UTF-8"?><a><b name="fuffy"><d>dog</d></b><c/></a>'
        
fromstringxml=Bag(stringxml)

A bag can also be serialized into different formats:

• XML
• pickle
• JSON
• etc.

In the following chapters we'll examine how to load and convert bags in many formats.
