public class HTMLTransformer
extends AbstractSAXTransformer
implements Configurable

Converts (escaped) HTML snippets into JTidied HTML. This transformer expects a list of elements, passed as comma separated values of the "tags" parameter. It records the text enclosed in such elements and pass it thru JTidy to obtain valid XHTML.

TODO: Add namespace support.

WARNING: This transformer should be considered unstable.

endElement

public void endElement(String uri,
                       String name,
                       String raw)
                throws SAXException

React on endElement calls that contain a tag to be tidied and run Jtidy on it, otherwise passthru.

Specified by:

endElement in interface ContentHandler

Overrides:

endElement in class AbstractSAXTransformer

Parameters:

uri - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.

name - The local name (without prefix), or the empty string if Namespace processing is not being performed.

raw - The raw XML 1.0 name (with prefix), or the empty string if raw names are not available.

Throws:

SAXException

ContentHandler.endElement(java.lang.String, java.lang.String, java.lang.String)

startElement

public void startElement(String uri,
                         String name,
                         String raw,
                         Attributes attr)
                  throws SAXException

Start buffering text if inside a tag to be normalized, passthru otherwise.

Specified by:

startElement in interface ContentHandler

Overrides:

startElement in class AbstractSAXTransformer

Parameters:

uri - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.

name - The local name (without prefix), or the empty string if Namespace processing is not being performed.

raw - The raw XML 1.0 name (with prefix), or the empty string if raw names are not available.

attr - The attributes attached to the element. If there are no attributes, it shall be an empty Attributes object.

Throws:

SAXException

           throws ProcessingException,
                  SAXException,
                  IOException
