I have a web scraper and I need to write a string from HTML code to my CSV file. The HTML code looks like this:

<div class="qa-static-ad-map-container">
       <img src="/app/static/media/staticmap.65e20ad98.svg" alt="Bucuresti - Ilfov, Bucuresti, 
         Sectorul 4" class="css-149mw5z">
</div>

I have to somehow get the text in the alt attribute; This is the code I've written:

c.OnHTML(".qa-static-ad-map-container img", func(e *colly.HTMLElement) { //class that contains wanted info
        writer.Write([]string{
            e.Attr("alt"),
        })
    })

It doesn't give any error and also shows me that the onHtml request has been made, but nothing is written in the file.

Do you see the attribute text, when you use e.g. `fmt.Println`? – Olaf Dietsche Sep 13 '22 at 09:33
No, apparently not – DvdiidI Sep 13 '22 at 09:46
If `fmt.Println` doesn't work either, maybe the function isn't called at all. – Olaf Dietsche Sep 13 '22 at 09:47
I have pretty much the same function for another source of an image and that one works fine – DvdiidI Sep 13 '22 at 09:51
use `fmt.Println(e)` to already see what you're dealing with. Maybe the selector is wrong? – Dolanor Sep 13 '22 at 10:30
I've tried this and it shows nothing – DvdiidI Sep 13 '22 at 10:58
Can you provide your full program? I'll try to help you then! – ossan Jan 05 '23 at 15:28
I managed to solve the problem; thanks anyway! – DvdiidI Jan 08 '23 at 13:24
