我如何计算每个章节中的小节总数。实际上，每个章节中的章节和每个章节中的小节都是如此article。基于此邮政我已尽力，但没有成功。（我是新手）。
这可能吗？有人能帮助我吗？
编辑
非常感谢您的及时回复。以下是我希望实现的一个非常简短的示例：
答案1
更新（2017/01/14）
我已将新版本上传cntperchap到 CTAN，现在称为xcntperchap，它允许通过标签和多个轨道级别进行跟踪。
编辑(2016/05/09)：更新：我发现了 中的一个奇怪的小错误xassoccnt，它导致了一些令人讨厌的值。请参阅本文底部的off-by-one新相似版本的临时版本。cntperchap
可以用于此（通常），但和cntperchap不匹配（我是这两个包的作者，所以我知道这一点并且必须（很快）纠正它）。cntperchapassoccnt
如果没有其他办法，请使用此by-pass解决方案：cntchap
