How to press button on web page by script in Powershell

Question

I want to press 'copy translation' button on translate.google.com by script, but I can not find it ID or call it without ID.

I tried:

.parsedhtml.body.GetElementsByClassName()

.parsedhtml.body.GetElementsById()

but I have no bloody idea how to find proper phrase in such complex web page. (I'm new to powershell.) I found div in which this button is.

Current code:

$text= 'Some text to translate'
$URI = 'https://translate.google.pl/#en/pl/'

$page = Invoke-WebRequest -Uri $URI$text -method get

$selector= 'tlid-copy-translation-button copybutton jfk-button-flat source-or-target-footer-button right-positioned jfk-button-hover jfk-button-active jfk-button-focused jfk-button-jfk-button-clear-outline'

$page.ParsedHtml.body.getElementsByTagName('div') | 
Where {$_.getAttributeNode('class').Value -eq $selector}
$submitButton.click()

$text2= Get-Clipboard
Write-Output $text2

You can use the Inspect element by right clicking. You'll find that the copy translation button has no id: <div class="jfk-tooltip-contentId">Copy translation</div> — GetShifting

Yes, that's what I know, my problem is to find any useful keyword to activate it. — Paweł Stępniak

This is really straight forward, as long as you know the element needed. For example, See this StackOverflow Q&A discussion as it would be similar to what you are after and a bit more.

Navigate the site form elements, not the Internet Explorer elements

$url = 'https://pwpush.com'

($FormElements = Invoke-WebRequest -Uri $url -SessionVariable fe)

It's working, but not for elements, which I want. I changed my code $page.AllElements | Where{$_.TagName -eq 'DIV'} and it's showing only part of the div's.

But why are you looking for div, vs link, tag, id, name, button, etc., element? As we all know, div are not elements. What site are you trying to hit, so that we can really see what you are working with?

Paweł Stępniak Over a year ago

Because this thing probably is not button. When I'm use 'Inspect', it highlights this div, so I tried to search it for some href phrase with links or something similar. But now I suspect it's a script. So now I understand even less. :(
