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:

bash
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:

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

XSD 源文件:

xml
<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>
