> NiFi provides the ability to ingest HTML but lacks the convenience to easily interact with that HTML once it has entered the flow. There should be a HTML Processing Bundle that provides mechanisms for manipulating and interacting with HTML data once it has entered the flow. Jsoup http://jsoup.org/ seems like a logical tool to use since it is mature and has a MIT license which would allow it to be incorporated into NiFi.
> “GetHTMLElement” should use the CSS selector-syntax (http://www.w3schools.com/cssref/css_selectors.asp) built into Jsoup to extract 0-N HTML elements from the original HTML input. This processor should support a delimited string of selectors allowing the user to build compound HTML element output. Each HTML element (or compound element result) extracted will create a new Flowfile where the element will be in either the Flowfile content or an attribute depending on the user configuration.
> “ModifyHTMLElement” should provide the ability to modify the original input HTML and overwrite any existing element values. The HTML element that will be modified can be selected by using the CSS selector-syntax
> “PutHTMLElement” should provide the ability to put a new HTML element anywhere in the original input HTML using CSS selector-syntax to indicate the position that the new HTML element should be placed.
> There seems to be a potential for adding more processors but this seems like a good start. Since there is a dependency on Jsoup and a potential for more processors to come I think it makes sense to add this logic as its own nar bundle but I could be wrong.
