和XML

<?xml version="1.0" encoding="utf-8"?>
    <form tab_name="news" upload_dir="news" enctype="multipart/form-data" action="actionfile.php">

<input type="text"      label="title"           name="title"></input>

    </form>

我必须承认，你的问题对我来说不是很清楚。我有一个类表单，它具有与表单相关的所有属性，并且所有表单元素（操作、文件上传目录、转换）都是通用的解析xml文件。好吧，很自然地，单个类永远无法处理HTML表单的所有复杂属性和子对象，您会遇到缺陷，对吗？我有一个类表单，它具有与表单相关的所有属性，并且对所有表单元素都是通用的（action，file upload dir，从db查询数据的元素id，…）来自解析xml文件。我有一个翻译类，它以_构造的形式建立。我有一个输入类，它具有输入的所有属性（名称、id、标签、值）；我在表单类中创建输入对象。我如何从输入类访问表单属性？好的，现在更清楚了。请将XML和表单类代码添加到您的问题中，以便我可以将它们连接在一起。
