Question

我正在尝试为每种类型的元素只创建一个适配器，所以我创建了一个bindings.xml文件：

<jxb:bindings node="//xs:attribute[@type='Id']"

所以，我的目的是解决“Id”类型的每个属性。问题是xjc告诉我“太多目标节点（3）”......但这正是我想要的!!

Answer 1

尝试添加multiple =“true”属性：

<jxb:bindings multiple="true" node="//xs:attribute[@type='Id']"

Answer 2

我最终遇到了类似的问题＆＃34;目标节点太多（3）＆＃34;然而，在任何网站上找不到任何答案......发布我经过大量追踪和错误后发现的解决方案...解决的基本思路＆＃34;太多的目标节点（3）＆＃34;是给出XSD中多个节点的完整XPATH。

以下是我的XSD：
