+ * Simple XML parser class.

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