Question

我有以下测试用例，但我发现XML部分没有按照我要求的顺序出现。我正在使用的SOAP API发出了以下消息：

<Search Type="Error">
    <ErrorCode>150</ErrorCode>
    <ErrorMessage>Invalid Entry : Invalid content was found starting with element &apos;Telephones&apos;. One of &apos;{Addresses}&apos; is expected. </ErrorMessage>
</Search

如果我编辑XML并首先使用地址提交，那么每个人都很高兴。

所以我需要在Numbers标签之前添加Address标签。这是我必须在Normalizing阶段或XmlEncoding阶段控制的东西吗？

任何人都可以使用下面的简单示例解释我是如何做到这一点的，我可以在生成的xml中的Numbers标记之前获取Address标记吗？

// First test we can get from php data structure to xml

又快又脏：

您需要做的只是更改Contact类中的属性和/或getter方法的顺序（取决于您的属性访问者类型）。

现在清除序列化程序和/或opcache-cache，并享受XML输出中更改的顺序。

使用Symfony Serialiser创建XML时，如何控制标签排序？
