Find the span text, if parent div text has certain value-CodePudding

I am by no ways a developer. I get by by google, but this issue has a depth I do not understand.

If you can explain what I am lacking in programming knowledge it'd be appreciated.

With powershell I can get all .Text from whatever div I choose. However I cannot figure out how to find the Text from a within a div whose .Text is "abc"

$allGames.Text contains all the game titles, so far so good:

[System.Reflection.Assembly]::LoadFrom("{0}\WebDriver.dll" -f $PathToFolder)
    if ($env:Path -notcontains ";$PathToFolder" ) {
        $env:Path  = ";$PathToFolder"
    }
    $ChromeOptions = New-Object OpenQA.Selenium.Chrome.ChromeOptions
    $ChromeOptions.AddArgument('start-maximized')
    $ChromeDriver = New-Object OpenQA.Selenium.Chrome.ChromeDriver($ChromeOptions)
           
    $ChromeDriver.Url = $uri
    #sometimes site is slow, 5s should be enough
    Start-Sleep -Seconds 5
    $allGames = $ChromeDriver.FindElementsByCssSelector("div.result-title.gameName")

And inside that is a whose Text I want to retrieve. Neither names of the nor is unique. There's hundreds of divs and spans with the same name. So I can't access them directly.

I only want the text from the span, if its div has the text "abc"

The rudimentary knowledge I have with powershell tells me to do this

foreach ($game in $allGames) {
    $game.GetType() #=RemoteWebElement
    if ($game.Text -eq "abc") {
        Write-Host "Found something!"
        $span = $game.FindElementsByCssSelector("span.search-listing-count-text")
        $span.Text
    }

}

However $span contains nothing

I don't understand if I'm failing at understanding Selenium (which I don't even know what it is. Google told me I could use it to find stuffs on sites) or if I'm failing to understand the object oriented aspects of powershell (which I don't :))

What am I missing?

The html snippet:

<div class="search-results">
    <div class="result-title gameName">abc
        </div>
    <div class="result-info">
        <span class="search-listing-count-text">123
            </span>
        </div>
</div>

Your problem: You find the div with abc Than you need to go BACK 1 level to the: And then you want to find your div. The div you search is NOT a Child of the abc div

CssSelector and going back is not an option, so I used Xpath (Google Xpath for more info). Maybe you need to use "/..//" (remove the first .)

$span = $game.FindElementByXPath("./..//span[@class='search-listing-count-text']")

Note: Running selenium from powershell, thats new for me, leerling everyday. Nice!

CodePudding user response：

Rebuilding the HTML you will get:

<div class="search-results">
    <div class="result-title gameName">abc</div>
    <div class="result-info">
        <span class="search-listing-count-text">123</span>
    </div>
</div>

Now, allGames would contain the _DIV_s with classnames result-title and gameName

$allGames = $ChromeDriver.FindElementsByCssSelector("div.result-title.gameName")

The required SPAN is the descendent of the DIV which is a sibling to the collected node within the list $allGames.

Solution

To select the required SPANs with respect to the nodes in the list $allGames you can use the following Locator Strategy:

XPath:

foreach ($game in $allGames) {
    $game.GetType() #=RemoteWebElement
    if ($game.Text -eq "abc") {
        Write-Host "Found something!"
        $span = $game.FindElementsByXPath("//ancestor::div[1]//div[@class='result-info']/span")
        $span.Text
    }
}
