Description:

Modifies the value of an existing HTML element. The desired element to be modified is located by using CSS selector syntax. The incoming HTML is first converted into a HTML Document Object Model so that HTML elements may be selected in the similar manner that CSS selectors are used to apply styles to HTML. The resulting HTML DOM is then “queried” using the user defined CSS selector string to find the element the user desires to modify. If the HTML element is found the element’s value is updated in the DOM using the value specified “Modified Value” property. All DOM elements that match the CSS selector will be updated. Once all of the DOM elements have been updated the DOM is rendered to HTML and the result replaces the flowfile content with the updated HTML. A more thorough reference for the CSS selector syntax can be found at “http://jsoup.org/apidocs/org/jsoup/select/Selector.html”
