Code example issue on README

[otokunaga2]

Hi! Thank you for excellent OSS.

I would like to try this library for my personal project.

However, when I tried to use this library along with README, the following example seemed not working in my environment. So could you share the correct information?

my environment info is as follows

• Golang: go version go1.14.2 linux/amd64
• WSL: Ubuntu 18.04 LTS

//not worked
list := range htmlquery.Find(doc, "//a/@href")  
for n := range list{
    fmt.Println(htmlquery.InnerText(n)) // output @href value without A element.
}
//=> # command-line-arguments
//./main.go:16:34: cannot use n (type int) as type *html.Node in argument to htmlquery.InnerText

//worked
list := htmlquery.Find(doc, "//a@href")
for _, val := range list{
    fmt.Println(htmlquery.InnerText(val))
}
//=>More information...

Sorry, the example about //a/@href is wrong in the README. I will fix it. Thanks for feedback.

list := range htmlquery.Find(doc, "//a/@href")  
for _, node := range list{
    fmt.Println(htmlquery.InnerText(node)) 
}
