如何用XML表示列表数据 [英] How to represent list data in XML

问题描述

我正在为我的当前用例设计XML文档.我的用例是-

I am working on designing the XML document for my current use case. My use case is-

给出一个ID，我可以得到检查分数和才能分数以及类别数.每个类别都有类别编号，检查分数和人才分数.

Given an id, I can have check-score and talent-score and number of categories. And each category will have category-id, check-score and talent-score.

因此，假设我有两个ID，则上面的数据将存在于两个ID中.

So suppose if I have two id's, then the above data will be there in two id's.

例如，下面是我基于单个id创建的XML-

For example, below is my XML that I have created basis on single id-

<?xml version="1.0" encoding="UTF-8" ?>
    <id>0</site-id>
    <check-score>0.5</check-score>
    <talent-score>0.2</talent-score>
    <categories>
        <category-id>123</category-id>
        <check-score>0.5</check-score>
        <talent-score>0.2</talent-score>
    </categories>
    <categories>
        <category-id>321</category-id>
        <check-score>0.2</check-score>
        <talent-score>0.4</talent-score>
    </categories>

如果我有另一个值为 1 的 id 以及与该 id 相关的相应内容，将会发生什么.意思是，在上面的示例中，我该如何表示第二个ID和与之相关的其他组件?如果我有两个ID，我应该做这样的事情吗?

What will happen if I have another id with value as 1 and corresponding things related to that id. Meaning, how do I represent second id and other components related to that in my above example? Should I do something like this if I have two id's?

<?xml version="1.0" encoding="UTF-8" ?>
    <id>0</site-id>
    <check-score>0.5</check-score>
    <talent-score>0.2</talent-score>
    <categories>
        <category-id>123</category-id>
        <check-score>0.5</check-score>
        <talent-score>0.2</talent-score>
    </categories>
    <categories>
        <category-id>321</category-id>
        <check-score>0.2</check-score>
        <talent-score>0.4</talent-score>
    </categories>

    <id>1</site-id>
    <check-score>0.2</check-score>
    <talent-score>0.3</talent-score>
    <categories>
        <category-id>289</category-id>
        <check-score>0.3</check-score>
        <talent-score>0.7</talent-score>
    </categories>
    <categories>
        <category-id>987</category-id>
        <check-score>0.1</check-score>
        <talent-score>0.5</talent-score>
    </categories>

也许有可能，我可以有多个id，所以我不确定为上述用例编写XML的正确方法.

And it might be possible, I can have multiple id's so I am not sure what is the right way to write an XML for my above use case.

有人可以帮我吗?

推荐答案

我遵循XML中的将容器用于未绑定的多重性"规则.

I follow the rule of "use containers for unbound multplicity" in XML.

这通常更易于使用，更易于在模式中表达，并且全方位一致且易于处理和扩展.此外，使用自动序列化/类型映射器可以很好地支持使用这样的方法.如上面的第二个示例所示，为此类结构化数据创建混合模式标记将导致混乱，并且需要进行特殊处理.

This is generally easier to consume, cleaner to express in schemas, and all-around consistent and simple to deal with and extend. In addition, using an approach like this is well supported using automatic serialization/type mappers. As shown above in the 2nd example, creating mixed mode markup for such structured data will result in a mess and requires special handling to deal with.

例如，将容器用于多重性:

For example, to use containers for the multiplicity:

<someRelevantRootElement>
  <sites>
    <site site-id="0">
      <!-- not sure what scores are doing there -->
      <categories>
        <category category-id="123">
          <scores check="0.5" talent="0.2" />
        </category>
        <category category-id="..">
          <!-- .. -->
        </category>
        <!-- more categories? -->
      </categories>
    </site>
    <site side-id="..">
      <!-- .. -->
    </site>
    <!-- more sites? -->
  </sites>
</someRelevantRootElement>

还请注意，我将某些元素转换为属性.将元素用作"id"几乎总是错误的，因为id 描述了某些信息的一个方面(阅读:element).

Also note that I converted some elements to attributes. Using an element for an "id" is almost always wrong as an id is describing an aspect of some information (read: element).

当然，可能是得分是容器，并且类别(id)只是此类得分信息的方面(的一个属性)(元素).

Of course, it could be the case that scores are the container, and the category (id) is just an aspect of (an attribute of) such score information (element).

无论如何，我敦促使用容器的无限制多重性.它使生活更轻松.

In any case, I urge the use of containers-for-unbound-multiplicity. It makes life easier.
