我有这个 Playground :https://go.dev/play/p/uEpYEWaQaV0 但没有得到什么问题,为什么它不工作!我得到了错误:
invalid character entity &ccb
我的代码是:
package main
import (
"encoding/xml"
"fmt"
)
type catalog struct {
Id string `xml:"id"`
}
type price struct {
Subtotal int `xml:"subtotal"`
Currency string `xml:"currency"`
Total int `xml:"total"`
PriceStatus string `xml:"price_status"`
}
type image struct {
Url string `xml:"url"`
Id int `xml:"id"`
}
type product struct {
Id int `xml:"id"`
RetailerId int `xml:"retailer_id"`
Image image `xml:"image"`
Price int `xml:"price"`
Currency string `xml:"currency"`
Name string `xml:"name"`
Quantity int `xml:"quantity"`
}
type order struct {
Product product `xml:"product"`
Catalog catalog `xml:"catalog"`
Price price `xml:"price"`
}
type Iq struct {
XMLName xml.Name `xml:"iq"`
Order order `xml:"order"`
}
func main() {
contents := `<iq from="s.whatsapp.net" id="162.120-3" type="result">

iq := &Iq{}
err := xml.Unmarshal([]byte(contents), &iq)
if err != nil {
panic(err)
}
fmt.Printf("%v\n", iq.Order)
}
最佳答案
以 @collapsar 的回答为基础...
尽管 XML 格式错误,您仍然可以通过创建 Decoder
实例并关闭 Strict
模式来处理它:
d := xml.NewDecoder(bytes.NewReader([]byte(contents)))
d.Strict = false
err := d.Decode(&iq)
if err != nil {
panic(err)
}
fmt.Printf("%v\n", iq.Order)
关于xml - 什么是无效字符实体 &ccb,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/72120226/
