使用 xsdgen 解组 XML
Unmarshaling XML in go with xsdgen
我正在尝试用 golang 解析一个 xml 文件。
我使用 xsdgen 生成结构部分
我无法用 xml.Unmarshal(byteValue, &data) 解析文件
我希望程序打印：GrandTotalAmount.Value 这是 671.15 但它正在打印 0.
变量 data 似乎是空的，因为这一行没有像我预期的那样工作：
xml.Unmarshal(byteValue, &data)
我没有看到任何编译错误（或者我不知道在哪里可以找到它们）
我觉得我错过了什么，你能帮帮我吗？

我认为这与 Go Issue #13400 有关。名称空间前缀似乎有问题。实际上，您可以在解组时忽略结构标签中的前缀。
以下代码应该适合您：

我用xsdgen生成ISO20022的相关go代码时，遇到了同样的问题。应该是xsdgen包里面的一些事情。我已经阅读了所有关于 xsdgen 配置的选项，但是没有忽略添加带有 XMLTag 的命名空间的选项。
您可能会专注于 xsdgen 包的实现，或者只是在生成代码的基础上手动省略额外的命名空间。
我正在尝试用 golang 解析一个 xml 文件。
我使用 xsdgen 生成结构部分
我无法用 xml.Unmarshal(byteValue, &data) 解析文件
我希望程序打印：GrandTotalAmount.Value 这是 671.15 但它正在打印 0.
变量 data 似乎是空的，因为这一行没有像我预期的那样工作：
xml.Unmarshal(byteValue, &data)
我没有看到任何编译错误（或者我不知道在哪里可以找到它们）
我觉得我错过了什么，你能帮帮我吗？

我认为这与 Go Issue #13400 有关。名称空间前缀似乎有问题。实际上，您可以在解组时忽略结构标签中的前缀。
以下代码应该适合您：

"fmt"
"io/ioutil"
"log"
"os"
)
type AmountType struct {
Value float64 `xml:",chardata"`

我用xsdgen生成ISO20022的相关go代码时，遇到了同样的问题。应该是xsdgen包里面的一些事情。我已经阅读了所有关于 xsdgen 配置的选项，但是没有忽略添加带有 XMLTag 的命名空间的选项。
您可能会专注于 xsdgen 包的实现，或者只是在生成代码的基础上手动省略额外的命名空间。
