 /**
  * Proof-of-concept lexer that uses the PEAR package XML_HTMLSax3 to parse HTML.
- * 
+ *
  * PEAR, not suprisingly, also has a SAX parser for HTML.  I don't know
  * very much about implementation, but it's fairly well written.  However, that
  * abstraction comes at a price: performance. You need to have it installed,
  * and if the API changes, it might break our adapter. Not sure whether or not
  * it's UTF-8 aware, but it has some entity parsing trouble (in all areas,
  * text and attributes).
- * 
+ *
  * Quite personally, I don't recommend using the PEAR class, and the defaults
  * don't use it. The unit tests do perform the tests on the SAX parser too, but
  * whatever it does for poorly formed HTML is up to it.
- * 
+ *
  * @todo Generalize so that XML_HTMLSax is also supported.
- * 
+ *
  * @warning Entity-resolution inside attributes is broken.
