* Simple XML parser class.

|
|
* This class is a simplified version of XML_Parser2.
|
|
* In most XML applications the real action is executed,
|
|
* when a closing tag is found.
|
|
*
|
|
* XML_Parser2_Simple allows you to just implement one callback
|
|
* for each tag that will receive the tag with its attributes
|
|
* and CData.
