public class CommentStripper
The CommentStripper class is a filter that removes all comments and processing instructions. It also concatenates text nodes that are split by comments and PIs. This follows the rules for processing stylesheets; it is also used for removing comments and PIs from the tree seen by XPath expressions used to process XSD 1.1 assertions
