Description

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
