Class Identity

org.codelibs.nekohtml.filters.DefaultFilter

org.codelibs.nekohtml.filters.Identity

All Implemented Interfaces:

org.apache.xerces.xni.parser.XMLComponent, org.apache.xerces.xni.parser.XMLDocumentFilter, org.apache.xerces.xni.parser.XMLDocumentSource, org.apache.xerces.xni.XMLDocumentHandler, HTMLComponent

public class Identity
extends DefaultFilter

This filter performs the identity operation of the original document event stream generated by the HTML scanner by removing events that are synthesized by the tag balancer. This operation is essentially the same as turning off tag-balancing in the parser. However, this filter is useful when you want the tag balancer to report "errors" but do not want the synthesized events in the output.

Note: This filter requires the augmentations feature to be turned on. For example:

  XMLParserConfiguration parser = new HTMLConfiguration();
  parser.setFeature("http://cyberneko.org/html/features/augmentations", true);
 

Note: This isn't exactly the identify transform because the element and attributes names may have been modified from the original document. For example, by default, NekoHTML converts element names to upper-case and attribute names to lower-case.
