GetHTMLElement removes content from resulting flowfiles even when destination is attribute

As noted in StackOverflow, GetHTMLElement processors cannot be chained because the success relationship clears the flowfile content even if the destination is an attribute. I propose the logic be changed to the following:

• Destination = content
• Replace the flowfile content for the success relationship
• Maintain the content for original
• Destination = attribute
• Maintain the content for success and original
• Add a property descriptor for the attribute name
• Name attributes Attribute.1 as in Extract* in the event that multiple elements are matched
