演示如何打印文档中每个 Office Math 节点的节点结构。

public void OfficeMathToText()
{
    Document doc = new Document(MyDir + "DocumentVisitor-compatible features.docx");
    OfficeMathStructurePrinter visitor = new OfficeMathStructurePrinter();

    // 当我们得到一个复合节点来接受文档访问者时，访问者访问接受节点，
    // 然后以深度优先的方式遍历该节点的所有子节点。
    // 访问者可以读取和修改每个访问过的节点。
    doc.Accept(visitor);

    Console.WriteLine(visitor.GetText());
}

/// <summary>
/// 遍历节点的子节点的非二叉树。
/// 以字符串形式创建所有遇到的 OfficeMath 节点及其子节点的映射。
/// </summary>

    public OfficeMathStructurePrinter()

    }

    /// <summary>
