我目前正在尝试将java库的一部分转换为c库，以便在unity中使用。在这个java库中，有些类是从xml文件生成的，我有xml文件，但因为我从来没有这样做过，无论是在java还是在c#。
我做了一些研究，找到了将.xml文件转换为.cs类的不同方法，但找不到有关.xml应该具有的语法的文档。
我尝试使用xsd.exe工具，并尝试从一个xml文件创建和创建xsd文件，但当我尝试生成.cs文件时，出现以下错误： Error: Can only generate one of classes or datasets. 然后我做了一些研究，发现了另一个工具xsd2code，所以我尝试将它与相同的.xml文件一起使用，以获得一个.cs文件，但它引发了一个错误，抱怨结构：

C:\Program Files (x86)\Xsd2Code>Xsd2Code.exe Vehicle.xml Vehicle.cs

Xsd2Code Version 3.4.0.32990
Code generation utility from XML schema files.

Error: Declaración XML inesperada. La declaración XML debe ser el primer nodo del documento y no pueden aparecer espacios en blanco delante. Línea 2, posición 3.
        SubType: Unspecified

        Rule:

我将翻译它，因为它是西班牙语的：错误：意外的xml声明。xml声明必须是第一个节点，并且之前不能包含空格。第2行，位置3。
以下是特定文件的第一行：

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:hfp="http://www.w3.org/2001/XMLSchema-hasFacetAndProperty" targetNamespace="http://www.w3.org/2001/XMLSchema" blockDefault="#all" elementFormDefault="qualified" version="1.0" xml:lang="EN">
<?xml version="1.0" encoding="UTF-8"?>
<traciClass>
    <name>Vehicle</name>

编辑：我纠正了它作为第一个评论说，但现在我收到

Error: Schema validation failed:
El elemento 'traciClass' no es compatible en este contexto.
        SubType: Unspecified

        Rule:

The element traciClass is not compatible in this context.

原帖子继续：
这是一个模板，说明了在xml for java中应该如何定义不同的对象，但是我想知道对于c#，这种结构是否会有所不同。

这是xml语法的问题吗？
