AWS EC2 Image List Version 1

This handler will be used primarily in a loop to iterate over multiple EC2 image instances. In order to be used by the Loop handler, a single value is returned as an escaped XML string. called "Instance List".

The Instance List will have the following format: <images> <image>ari-fe916297</image> <image>ari-8b779ae2</image> <image>ari-926b8bfb<image> </instances>

To setup the Loop handler, refer to the Image List from this handler for 'Data Source' and use '/images/image'as the 'Variable Path'.

The describe_images function is the base AWS::EC2 gem call we are using for this handler and returns a multi-level hash/array nest with a top level hash key of "imagesSet".

The imagesSet has the following pseudo-xml form. Elements with the <item> tag are array members and are referenced by numerical index.

All others are hash members and are references by element/key name.

To retrieve the imageId, for example, simply flatten the above structure by removing inapplicable items

Treat items as arrays and all other members as hash keys. Doing so, we can reference imageId value in the following manner:

@base_aws_object.imagesSet.item[index].imageId
