package encoding/xml
DecodeElement works like xml.Unmarshal except that it takes a pointer to the start XML element to decode into v. It is useful when a client reads some raw XML tokens itself but also wants to defer to Unmarshal for some elements.
Golang encoding/xml.Decoder.DecodeElement() function usage example
type Rect struct {
Date string `xml:"data-date,attr"`
Num string `xml:"data-count,attr"`
}
func (c *Contribution) UnmarshalXML(d *xml.Decoder, start xml.StartElement) error {
var i Rect
err := d.DecodeElement(&i, &start) // <- here
if err != nil {
return err
}
c.Date, err = time.Parse(dateFormat, i.Date)
if err != nil {
return err
}
c.Num, err = strconv.Atoi(i.Num)
if err != nil {
return err
}
return nil
}
