Class Identity

org.cyberneko.html.filters.DefaultFilter
org.cyberneko.html.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
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.
