if the attribute is not present, it should return null, if it's present and not set then it will return empty string. I think that's the case in your example, if so. Then you should use equal
method to compare string rather than ==
operator.
Below example is about google search box, xxx attribute is not present for search box and so it will return null
driver = new ChromeDriver();
driver.get("http://google.com");
WebElement ele = driver.findElement(By.name("q"));
String attr = ele.getAttribute("xxx");
if (attr == null){
System.out.print("Attribute does not exist");
}
else if (attr.equals("")){
System.out.print("Attribute is empty string");
}
You can try it out yourself by writing the following html and saving it as test. html:
<html>
<head>
</head>
<body>
<p id="one">one</p>
<p id="two" data-se="">two</p>
<p id="three" data-se="something">three</p>
</body>
</html>
Then write a web driver script that looks like this:
driver.get("file:///<PATH_TO_HTML_ABOVE>/test.html");
WebElement one = driver.findElement(By.id("one"));
WebElement two = driver.findElement(By.id("two"));
WebElement three = driver.findElement(By.id("three"));
System.out.println("Does one have the data-se attribute?: '" + one.getAttribute("data-se") + "'");
System.out.println("Does two have the data-se attribute?: '" + two.getAttribute("data-se") + "'");
System.out.println("Does three have the data-se attribute?: '" + three.getAttribute("data-se") + "'");
Which will give you the following output:
Does one have the data-se attribute?: 'null'
Does two have the data-se attribute?: ''
Does three have the data-se attribute?: 'something'
