IM正在尝试解析xml：
附加xml，因为它对于此处而言太长https://drive.google.com/file/d/1CPleC1gBAR6n7lcyiR_zVMEjkowo3gUU/view?usp=sharing

type L1CProduct struct {
    XMLName xml.Name `xml:"n1:Level-1C_User_Product"`
    N1GeneralInfo N1GeneralInfo `xml:"n1:General_Info"`
}

type N1GeneralInfo struct {
    XMLName xml.Name `xml:"n1:General_Info"`
    ProductInfo ProductInfo `xml:"Product_Info"`
    SpectralInformationList SpectralInformationList `xml:"Product_Image_Characteristic>Spectral_Information_List"`
}

type SpectralInformationList struct {
    XMLName xml.Name `xml:"Spectral_Information_List"`
    SpectralInformation []SpectralInformation `xml:"Spectral_Information"`
}

type SpectralInformation struct {
    XMLName xml.Name `xml:"Spectral_Information"`
    BandId string `xml:"bandId,attr"`
    PhysicalBand string `xml:"physicalBand,attr"`
}

type ProductInfo struct{
    XMLName xml.Name `xml:"Product_Info"`
    ProductStartTime string `xml:"PRODUCT_START_TIME"`
    GenerationTime string `xml:"GENERATION_TIME"`
    ProductUri string `xml:"PRODUCT_URI"`

}

func parseXml() {
    // Open our xmlFile

    // xmlPath := inProcessPath + "/MTD_MSIL1C.xml"
    xmlPath := "/home/htc/Lizer/backend/InProcessResults/MTD_MSIL1C.xml"
    xmlFile, err := os.Open(xmlPath)
    // if we os.Open returns an error then handle it
    if err != nil {
        fmt.Println(err)
    }

    fmt.Println("Successfully Opened " + xmlPath)
    // defer the closing of our xmlFile so that we can parse it later on
    defer xmlFile.Close()

    // read our opened xmlFile as a byte array.
    byteValue, _ := ioutil.ReadAll(xmlFile)
    fmt.Printf("\nData: %s", byteValue)
    // we initialize our Users array
    var users L1CProduct
    // we unmarshal our byteArray which contains our
    // xmlFiles content into 'users' which we defined above
    xml.Unmarshal(byteValue, &users)
    fmt.Println(users.N1GeneralInfo.ProductInfo.ProductStartTime + "º")
    println(users.N1GeneralInfo.SpectralInformationList.SpectralInformation[1].BandId)
    // we iterate through every user within our users array and
    // print out the user Type, their name, and their facebook url
    // as just an example
    // for i := 0; i < len(users.N1GeneralInfo.SpectralInformationList.SpectralInformation); i++ {
    // for i := 0; i < 10; i++ {
    //     fmt.Println("Band Id: " + users.N1GeneralInfo.SpectralInformationList.SpectralInformation[i].BandId)
    //     fmt.Println("physicalBand: " + users.N1GeneralInfo.SpectralInformationList.SpectralInformation[i].PhysicalBand)
    // }

}

但是当文件被正确读取时，miXML结构是空的

fmt.Println(users.N1GeneralInfo.ProductInfo.ProductStartTime + "º")
    println(users.N1GeneralInfo.SpectralInformationList.SpectralInformation[1].BandId)

fmt.Println(users.N1GeneralInfo.ProductInfo.ProductStartTime + "º")
println(users.N1GeneralInfo.SpectralInformationList.SpectralInformation[1].BandId)

就像结构体是空的：输出：**
