示例1: handleSuccessfulResult
/**
* Performs checking on the parse result.
*
* The method will check if there are more text after the current cursor
* location and if so appends a new ezcTextElement object containing the
* text.
*
* It also checks if the $lastBlock contains the current program parser, if it
* does not it means the nesting in the current source code is incorrect.
*
* @param ezcTemplateCursor $lastCursor
* @param ezcTemplateCursor $cursor
*
* @throws ezcTemplateParserException if blocks are incorrectly nested.
*
* @return void
