以下是使用探针进行调试的解决方案

Here a solution with probe to debug

rules: [
     thru <div class="main">
     (div-count: 1)
      some [
        "<div" (probe ++ div-count) skip
      |
        "</div>" mark:  ( probe -- div-count   if div-count = 0 [insert mark "closing main div"]) skip 
      |  skip
     ]
  ]
parse/all content rules 

您的规则存在的问题是，永远不会或很少会减去div计数.解析指针会直接指向下一个打开的 div ，因为 to 始终是第一个满足的条件.

The problems with your rules are, that the div-count is never or seldom subtracted. The parse pointer goes straight to the next opening div as to is always the first fulfilled condition.

如果在成功情况后添加要结束，则可以突围或者更好地从解析中返回.如果不确定，请使用方括号将 [成功的子规则...分组]分组

You can break out or better return from parse if you add a to end after a successful condition. If you are unsure use brackets for grouping [ sucessful sub-rules ... to end ]

带有结束规则的示例

end-rule: [] ; or none
rules: [
    thru <div class="main">
    (div-count: 1)
    some [
        ["<div" (++ div-count) skip]
    |
        ["</div>"mark:  (-- div-count   if div-count = 0 [insert mark "closing main div"  end-rule: [to end]]) end-rule ]
    |  skip
]

]
