Class HTMLShredder

java.lang.Object
  org.erowid.sperowider.htmlshredding.HTMLShredder

All Implemented Interfaces:

HTMLElement

public class HTMLShredder

extends Object

implements HTMLElement

Takes an InputStreamReader and turns the data so streamed into an ordered collection of HTML elements. These elements include HTMLComment, HTMLKeywordTag HTMLMetaTag, HTMLTag, and HTMLText.

It's designed to be fed text representing a page. Then you can go through the collection of elements, adjust their qualities and then get a String (using GetDisplay(), which iterates through the getDisplay() of all the contained elements) that has the modified info in it.
