Question

我使用了xmlstarlet，用于以下

替换： xmlstarlet ed -u // author [text（）=＆＃39; Gambardella，Matthew＆＃39;] -v＆＃39; Gambardella＆＃39; bookstore.xml，位于以下XML文件中：

<?xml version="1.0"?>
<catalog>
   <book id="bk101">
      <author>Gambardella, Matthew</author>
      <title>XML Developer's Guide</title>
      <genre>Computer</genre>
      <price>44.95</price>
      <publish_date>2000-10-01</publish_date>
      <description>An in-depth look at creating applications 
      with XML.</description>
   </book>
   <book id="bk102">
      <author>Ralls, Kim</author>
      <title>Midnight Rain</title>
      <genre>Fantasy</genre>
      <price>5.95</price>
      <publish_date>2000-12-16</publish_date>
      <description>A former architect battles corporate zombies, 
      an evil sorceress, and her own childhood to become queen 
      of the world.</description>
   </book>
   <book id="bk103">
      <author>Corets, Eva</author>
      <title>Maeve Ascendant</title>
      <genre>Fantasy</genre>
      <price>5.95</price>
      <publish_date>2000-11-17</publish_date>
      <description>After the collapse of a nanotechnology 
      society in England, the young survivors lay the 
      foundation for a new society.</description>
   </book>

我如何使用book id标识符在xml文件中专门设置值而不是搜索和替换过程？

例如，对于书籍id =＆＃34; bk101＆＃34;，对于书籍id =＆＃34; bk103＆＃34;作者节点，必须成为Gambardella，无论它现在有什么（所以我们不搜索和替换，但是我们设置了值），对于book id =＆＃34; bk102＆＃34;，作者必须设置为say Clems Lebof。所以我们提供了一些逗号分隔的book id值，以及我们需要设置的相应值，因此输出最终会变为：

<?xml version="1.0"?>
<catalog>
   <book id="bk101">
      <author>Gambardella</author>
      <title>XML Developer's Guide</title>
      <genre>Computer</genre>
      <price>44.95</price>
      <publish_date>2000-10-01</publish_date>
      <description>An in-depth look at creating applications 
      with XML.</description>
   </book>
   <book id="bk102">
      <author>Clems Lebof</author>
      <title>Midnight Rain</title>
      <genre>Fantasy</genre>
      <price>5.95</price>
      <publish_date>2000-12-16</publish_date>
      <description>A former architect battles corporate zombies, 
      an evil sorceress, and her own childhood to become queen 
      of the world.</description>
   </book>
   <book id="bk103">

      <description>After the collapse of a nanotechnology 
      society in England, the young survivors lay the 
      foundation for a new society.</description>
   </book>

如何使用xmlstarlet完成上述工作？

Answer 1

更改XPath以匹配author的子book元素，其中id属性等于＆＃39; bk101＆＃39;或＆＃39; bk103＆＃39; ：

xmlstarlet ed -u "//book[@id='bk101' or @id='bk103']/author" -v 'Gambardella' bookstore.xml

xmlstarlet，更改xmlnodes，给出标识符节点列表
