Parser.visitAllNodesWith介绍

[英]Apply the given visitor to the current page. The visitor is passed to the accept() method of each node in the page in a depth first traversal. The visitor beginParsing() method is called prior to processing the page and finishedParsing() is called after the processing.
[中]将给定的访问者应用到当前页面。在深度优先遍历中，访问者被传递到页面中每个节点的accept()方法。在处理页面之前调用visitorbeginParsing()方法，在处理之后调用finishedParsing()。
