I haven’t done any recursive calls in a long time. After reading it, I suddenly woke up!

Copy code The code is as follows:




Statistics Element nodes


Test



TR & GT; & LT; TD & GT;
& LT; Form Name = "Form1" Action = "Method =" Post "& GT;
& LT; alue = " Test" >

/tr>

Start testing





In fact, the same effect as Baidu spider crawler can also be achieved through recursive calls! This is worth a try. Maybe you can use this method to write a sitemap generator!
