Selenium how to determine if element has child?

I am using Selenium via c#. I use this XPath to get all the children elements

element.FindElements(By.XPath("./child::*"));

Although if there is no child, it throws an error after a timeout. I am looking for a simple way to determine if it has a child or not to avoid the exception.

To do in Javascript:

var childElements = await element.findElements(By.xpath('.//*'));
    for (i = 0; i <= childElements.length; i++) {
        var elementId = await childElements[i].getAttribute("id");
        await console.log(elementId);
    }

The simplest way is:

boolean hasChildren(WebElement node) {
    return node.findElements(By.xpath("./descendant-or-self::*")).size() > 1;
}

bool HasChild(IWebElement element)
{
    //Save implicit timeout to reset it later 
    var temp = driver.Manage().Timeouts().ImplicitWait;

    driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(0);
    bool exists = element.FindElements(By.XPath(".//*")).Count > 0;
    driver.Manage().Timeouts().ImplicitWait = temp;

    return exists;
}

As per your question to get all the Child Nodes of a Parent Node you can use FindElements() method with following-sibling::* attribute within xpath as follows :

  • Sample Code Block :

    List<IWebElement> textfields = new List<IWebElement>();
textfields = driver.FindElements(By.XPath("//desired_parent_element//following-sibling::*"));

    Note : When FindElements() is used inconjunction with implicitly or explicitly waits, FindElements() method will return as soon as there are more than 0 items in the found collection, or will return an empty list if the timeout is reached.

  • XPath Details :

    • Description : This xpath technique is used to locate the sibling elements of a particular node.
    • Explanation : The xpath expression gets the all the sibling elements of the parent element located using desired_parent_element.

FindElements returns a list, so you can check the size of the list, if it is zero, it means there are no child elements

Java

List<WebElement> childs = rootWebElement.findElements(By.xpath(".//*"));
int numofChildren = childs.size();

C#

IReadOnlyList<IWebElement> childs = rootWebElement.FindElements(By.XPath(".//*"));
Int32 numofChildren = childs.Count;
