我有以下 XML 文件，当我使用下面的 JAVA 代码解组以下 XML 时。
我没有得到 case-manager 标签值。我使用 Innovation.getCasemanager() 获取，我得到了 NULL 值。实际上，这应该是返回 'dhocsta@umich.edu' 的值。
我实际上遇到了这个问题，因为 case-manager 标记包含 XML 属性。如果它不包含 XML 属性，那么我可以获得 case-manager 正确的值。
XML 文件：
<innovation file_number="0269">
<title>3D Static Strength Prediction Program</title>
<brief_description>3D Static Strength Prediction Program</brief_description>
<categories/>
<tags>
<tag>Healthcare</tag>
<tag>Manufacturing</tag>
<tag>_Other</tag>
</tags>
<full_description>test</full_description>
<case_manager first_name="Doug" last_name="Hockstad">dhocksta@umich.edu</case_manager>
<status>Published</status>
</innovation>
JAVA代码：
Unmarshaller unmarshaller = jc.createUnmarshaller();
unmarshaller.setSchema(schema);
unmarshaller.setEventHandler(validation);
Innovations innovation = (Innovations) unmarshaller.unmarshal(xmlSourceFileName);
