Is there a way to extract the source of an image in an HTML

  • 0

Is there a way to extract the source of an image in an HTML file using only one struct (with encode/xml)? Now I have something like this

type XML struct {
    A Image `xml:"div>img"`
}

type Image struct {
    I string `xml:"src,attr"`
}

And would be great to only declare something like this :

type Image struct {
    I string `xml:"div>img,src,attr"`
}

This is the HTML :

<div><div><img src="hello.png"/></div></div>

    Seems that a good way is to use the exp/html package, like this:

    package main

import (
    "exp/html"
    "strings"
)

func main() {
    a, _ := html.Parse(strings.NewReader(testString))
    println(a.FirstChild.FirstChild.NextSibling.FirstChild.FirstChild.FirstChild.Attr[0].Val)
}

var testString = `<div><div><img src="hello.png"/></div></div>`

    All this FirstChild and NextSibling are needed because exp/html constructs a “correct” html5 tree so this code is actually parsing this:

    <html>
    <head></head>
    <body>
        <div>
            <div>
                <img src="hello.png"/>
            </div>
        </div>
    </body>
</html>
