Xml 使用XPath选择节点以使用JAXB绑定类的子集

简化问题： 选择属性以字符串“Notification”结尾的所有XML节点的XPath是什么。此代码段中的第一个和第三个节点：

 <events>
   <event name="CreatedNotification" />
   <event name="InfoLog" />
   <event name="UpdatedNotification" />
 </events>

到

但它不起作用

另一种方法是尝试选择所有具有子节点“order summary”和“serial number”的节点，因为我知道只有通知对象具有这些节点

更新： @Lee Greco的解决方案正确地选择了我想要的节点，但不幸的是，继承插件与多个节点不兼容：

[ERROR] XPath evaluation of "//xs:complexType[substring(@name, string-length(@name)-string-length('Notification')+1)='Notification']" results in too many (8) target nodes

最后，我只是分别列举了它们

//xs:complexType[substring(name(), string-length(name()) - 12) = 'Notification']

表达式您要求元素名称以“通知”结尾的所有元素。您确实希望请求具有以“Notification”结尾的name属性的所有元素

请尝试以下方法：

//xs:complexType[substring(@name, string-length(@name)-string-length("Notification")+1)="Notification"]

我也有同样的问题。我发现XJC使用了一个

multiple

属性来允许多节点匹配

我还希望绑定应用于每个模式位置

xs:anyURI

不起作用，但我找到了一种使用

*

令牌的方法。我添加了

required=“false”

属性，以便忽略不包含任何匹配项的模式

<jxb:bindings schemaLocation="*">
  <jxb:bindings node="//xs:complexType[substring(name(), string-length(name()) - 12) = 'Notification']" multiple="true" required="false">
    <inheritance:implements>com.google.checkout.sdk.notifications.Notification</inheritance:implements> 
  </jxb:bindings>
</jxb:bindings>

com.google.checkout.sdk.notifications.Notification

编辑：我没有阅读问题的评论就发布了这个答案。对不起。我使用maven plugin

org.codehaus.mojo:jaxb2 maven plugin:1.5

和XJC plugin

org.jvnet.jaxb2_commons:jaxb2 basics项目：0.6.4

，它似乎是这样工作的…

我最终遇到了一个类似的问题“目标节点太多（3）”然而，在任何一个站点上都找不到任何答案…发布了我在经过大量跟踪和错误后发现的解决方案…解决“太多目标节点（3）”的基本思想是给出节点的完整XPATH，该节点在XSD中是多个的
