XSD 模式语言解析引擎与跨语言代码生成器

github.com/xuri/xgen

xgen 是 Go 语言编写的 XSD (XML Schema Definition) 工具基础库,其命令行工具的目标是将 XML 模式定义文件编译为包括 Go/C/Java/Rust/TypeScript 在内的多语言类型或类声明代码。

GitHub 开源:github.com/xuri/xgen

安装命令行工具:

xgen [<flag> ...] <XSD file or directory> ...
   -i <path> Input file path or directory for the XML schema definition
   -o <path> Output file path or directory for the generated code
   -p        Specify the package name
   -l        Specify the language of generated code (Go/C/Java/Rust/TypeScript)
   -h        Output this help and exit
   -v        Output version and exit

例如,下面的命令将遍历 xsd 目录中的 XML 模式定义文件,并在 output 目录中生成 Go 语言结构体声明代码:

xgen -i /path/to/your/xsd -o /path/to/your/output -l Go

XSD 源文件:

<schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://example.org/">
  <simpleType name="myType1">
    <restriction base="base64Binary">
      <length value="10" />
    </restriction>
  </simpleType>

  <complexType name="myType2">
    <simpleContent>
      <extension base="base64Binary">
        <attribute name="length" type="int"/>
      </extension>
    </simpleContent>
  </complexType>

  <complexType name="myType3">
    <simpleContent>
      <extension base="date">
        <attribute name="length" type="int"/>
      </extension>
    </simpleContent>
  </complexType>

  <complexType name="myType4">
    <sequence>
      <element name="title" type="string"/>
      <element name="blob" type="base64Binary"/>
      <element name="timestamp" type="dateTime"/>
    </sequence>
  </complexType>

  <simpleType name="myType5">
    <restriction base="gDay"/>
  </simpleType>
</schema>
