我有一个Word文档，其中包含一个内容控件XML。这是来自document.xml的内容控件的代码： [[[[]]]] 下面的单元测试表明，只有在使用命名空间前缀（例如“ ex”）的情况下，您才能将w:sdt元素绑定到具有XML命名空间（例如“ http://example.com”）的自定义XML元素。）放在w:prefixMappings元素的w:xpath和w:dataBinding属性中。不过，您的自定义XML元素不需要名称空间前缀。因此，以下两个XML文档都将起作用： <?xml version="1.0" encoding="utf-8"?> <ex:Root xmlns:ex="http://example.com"> <ex:Node>VALUE1</ex:Node> </ex:Root> <?xml version="1.0" encoding="utf-8"?> <Root xmlns="http://example.com"> <Node>VALUE1</Node> </Root> 这里是单元测试： using System;
