-// The key represents the current event type, and the value represents the depth of the current parsing. You can know the parsed event according to EVENTTYPE. For example, the result 'key: value' in this example means:
-// 0(START_DOCUMENT):0(Parse to the START_DOCUMENT, and the depth is 0), 2(START_TAG):1(Parse to the START_TAG node, and the depth is 1), 10(WHITESPACE):1(Parse to the WHITESPACE space, and the depth is 1), 2(START_TAG):2(Parse to the START_TAG title, and the depth is 2), ...
