xml - 从命令行列出 XML 节点的 XPath

Question

鉴于这个大型深层嵌套 XML 文档 (bookstore.xml) 的片段，我想知道 amazon 节点的完整路径。如何从命令行打印该路径？

<bookstore>
<book>
  <title lang="eng">Learning XML</title>
  <price>
    <retail>39.95</retail>
    <discounts>
      <amazon>29.99</amazon>
    </discounts>
    <currency>USD</currency>
  </price>
</book>
...
</bookstore>

理想情况下它应该是这样的:

old-gregg$ magic bookstore.xml amazon
/bookstore/book/price/discounts/amazon

Answer 1

我找到了 XMLStarlet它正是我在这里寻找的。使用 Homebrew 安装它:

$ brew update
$ brew install xmlstarlet
$ xml el bookstore.xml | grep amazon
/bookstore/book/price/discounts/amazon
