去1.11.2 xml意外的EOF

Question

I want to check if an submitted xml file is a valid xml or not so I check if it can be parsed. I do it like that:

const EmptyXml = `<?xml xmlns="http://www.w3.org/1999/xhtml"?>`

func CanParse(xmlData string) (bool, error) {
    if strings.TrimSpace(xmlData) == "" {
        return false, nil
    }
    type Tag struct {
        XMLName xml.Name
        Content string `xml:",innerxml"`
    }
    type Object struct {
        Items []Tag `xml:",any"`
    }
    var o *Object
    err := xml.Unmarshal([]byte(xmlData), &o)
    if err != nil {
        return false, err
    } else {
        return true, nil
    }
}

Sadly I end up with an error: unexpected EOF. Why is this?

Actually the method did work a month ago, and golang has not been updated since then so I´m still about to figure out what broke the method

It means that it expected an end tag. I've not done much XML recently, however I think you either have to add a closing </xml> or add question marks: <?xml xmlns="http://www.w3.org/1999/xhtml"?>
