Javascript 是否可以使用XPath获取此结果集？

我有一些XML，我正在使用javascript和XPath（1.0）作为学习过程。我能处理基本的事情，但把所有的事情放在一起就是让我把头发拔出来

我的XML文件包含多本这样格式的书

<bookstore>     <!-- Added by edit -->

这使我按顺序获得了这3个元素（标题、艺术品、价格；标题、艺术品、价格等），但如果我添加self:：description/short或child:：*/short之类的内容，我就不会得到任何关于描述的返回

---

最糟糕的情况是，我可以单独访问所有部分。

如果元素名称是唯一的，您可以对

子代或self::

轴使用这种简单的方法：

/bookstore/book[@special='true' and @homepage='true']/descendant-or-self::*[self::title | self::artwork | self::price | self::short | self::score | self::amount]

其产出是：

Belgariad 1: Pawn of Prophecy

7.99 
4 
340 
An ancient prophecy & and a maimed God...--nl--Long ago, the evil God Torak fought a war to obtain an object of immense power - the Orb of Aldur.But Torak was defeated and the Orb reclaimed by Belgarath the sorcerer.

---

如果它们不是唯一的，则需要在谓词中使用

parent:：

轴指定父项：

/bookstore/book[@special='true' and @homepage='true']/descendant-or-self::*[self::title | self::artwork | self::price | self::short[parent::description] | self::score[parent::rating] | self::amount[parent::rating]]

本例中的输出应相同

---

请注意，输出的顺序是源文件顺序，而不是XPath表达式的顺序。

如果您的XPath版本支持它，则可以使用较短的表达式：

/bookstore/book[@special='true'][@homepage='true']/(title, artwork, price, //short, //score, //amount)

---

是的，就是这样。谢谢！对于最后3个项目，我尝试了genderant或self：：，但我没有想到在谓词之前使用它。一个如此接近但迄今为止的案例：（我认为我遇到的问题有一半是因为它是1.0版本，所以任何带有括号的东西，比如你的建议，最终都会出现错误。我确实为2.0或更高版本提出了一些解决方案，这些解决方案在XPath测试网站上有效，但我自己不会。

/bookstore/book[@special='true'][@homepage='true']/(title, artwork, price, //short, //score, //amount)
