C# – Ignoring exceptions when using c# selenium webdriverWait wait.untill() function

cnetseleniumselenium-webdrivervisual-studio-2013

In order to check if an Element is exists and clickble i'm trying to write a boolean method which will wait for the element to be enabled and displyed using C# selenium's webDriverWait as follow:

webDriverWait wait = new webDriverWait(driver, timeSpan.fromSeconds(60));

Wait.untill( d => webElement.enabled() && webElement.displayed());

In case the above conditions do not happen, I want the method to return 'false'. The problem is that I get exceptions thrown.
How can I ignore exceptions such as noSuchElementException and timeOutException in case they are thrown?
I have tried to use try catch block but it didn't help and exceptions were thrown.

WebDriverWait implements DefaultWait class that contains public void IgnoreExceptionTypes(params Type[] exceptionTypes) method.

You can use this method for defining all the exception types you want to ignore while waiting for element to get enabled before clicking.

For example :

WebDriverWait wdw = new WebDriverWait(driver, TimeSpan.FromSeconds(120));
wdw.IgnoreExceptionTypes(typeof(NoSuchElementException), typeof(ElementNotVisibleException));

In the preceding code wait will ignore NoSuchElementException and ElementNotVisibleException exceptions

Python – Get HTML source of WebElement in Selenium WebDriver using Python

You can read the innerHTML attribute to get the source of the content of the element or outerHTML for the source with the current element.

Python:

element.get_attribute('innerHTML')

Java:

elem.getAttribute("innerHTML");

C#:

element.GetAttribute("innerHTML");

Ruby:

element.attribute("innerHTML")

JavaScript:

element.getAttribute('innerHTML');

PHP:

$element->getAttribute('innerHTML');

It was tested and worked with the ChromeDriver.

Javascript – way to get element by XPath using JavaScript in Selenium WebDriver

You can use document.evaluate:

Evaluates an XPath expression string and returns a result of the specified type if possible.

It is w3-standardized and whole documented: https://developer.mozilla.org/en-US/docs/Web/API/Document.evaluate

function getElementByXpath(path) {
  return document.evaluate(path, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;
}

console.log( getElementByXpath("//html[1]/body[1]/div[1]") );

<div>foo</div>

There's also a great introduction on mozilla developer network: https://developer.mozilla.org/en-US/docs/Introduction_to_using_XPath_in_JavaScript#document.evaluate

Alternative version, using XPathEvaluator:

function getElementByXPath(xpath) {
  return new XPathEvaluator()
    .createExpression(xpath)
    .evaluate(document, XPathResult.FIRST_ORDERED_NODE_TYPE)
    .singleNodeValue
}

console.log( getElementByXPath("//html[1]/body[1]/div[1]") );

<div>foo/bar</div>
