可以看出XMind的存储结构是由多个sheet组成的，然后每个sheet中包含一个顶端的topic，然后topic中有chillren节点用于包含子topic。至此，我们自然可以通过遍历XML文件的方式来解析Xmind文件。这种方法适用于任何的语言。

而使用Java语言进行解析的话,则有另外的方法。因为XMind核心代码是用Java进行编写的，所以我们可以直接引入XMind核心Jar来使用相应的API来解析XMind文件。如何使用XMindAPI，可以详见UsingXmindAPI.

简单示例

引入org.xmind.core Jar文件
在XMind的安装目录\plugins目录搜索org.xmind.core，找到org.xmind.core.****.jar文件引入到你的项目中，或在pom.xml中引入

<dependency>
  <groupId>com.github.eljah</groupId>
  <artifactId>xmindjbehaveplugin</artifactId>
  <version>0.8</version>
</dependency>

   IWorkbookBuilder builder = Core.getWorkbookBuilder();//初始化builder
        IWorkbook workbook = null;
        try {
            workbook = builder.loadFromPath(path);//打开XMind文件
        } catch (IOException e) {
            e.printStackTrace();
        } catch (CoreException e) {
            e.printStackTrace();
        }
        ISheet defSheet = workbook.getPrimarySheet();//获取主Sheet
      rootTopic = defSheet.getRootTopic(); //获取根Topic
