Cannot find element when the XPath expression is null.

[Jianah Javier]

Hi All

I was trying to double click on div element and an error appears "Cannot find element when the XPath expression is null." Hoping you can help me on this. When you mouseover the textarea there is a tooltip showing Double click to add/edit contents.

Please Note that the property file is working fine in other method. 

HTML:

<div id="description">

<div class="template">

<div class="dataRow lang english">

<div class="formCellLeft">

<div class="formCellRight">

<div class="inputText ui-corner-all editorDIV" title="Double click to add/edit contents."/>

</div>

</div>

</div>

</div>

xpath: .//*[@id='description']/div/div/div[2]/div 

Here is my code:

public static void dclickTxtarea(String object, String data){

try{

WebElement element = driver.findElement(By.xpath(OR.getProperty(object)));

Actions action = new Actions(driver).doubleClick(element);

action.build().perform();

}catch(Exception e){

Log.info("Unable to double click on Webelement " + object + "---" + e.getMessage());

}

}

Looks like:

OR.getProperty(object)

returns null.

What is the value of object, and what does OR.getProperty() do?

[Jianah Javier]

Hi Mark,

I am calling a property file and the property file(OR) has an object and value of xpath. See below simple code and still this will return with the same error:

WebElement element = driver.findElement(By.xpath(.//*[@id='description']/div/div/div[2]/div ));

Actions action = new Actions(driver).doubleClick(element);

action.build().perform();

The given selector  is either invalid or does not result in a WebElement. The following error occurred:

InvalidSelectorError: Unable to locate an element with the xpath expression  because of the following error:

SyntaxError: The expression is not a legal expression.

The given selector //[@id='description']/div/div/div[2]/div is either invalid or does not result in a WebElement. The following error occurred:

Hi,

 Try to use below Xpath in the code,

Xpath: //div[@id='description']/div/div/div[2]/div 

[Shailendra Bhadauria]

Hi Jianah,

I asked you to remove dot only. Ok let it be kindly use below:

//*[@id='description']/div/div/div[2]/div

Regards

Shailendra

Hi,

Why can't you try to create xpath with title here. some thing like this //div[@title='Double click to add/edit contents.']

please check if the above xpath returning required single or multiple elements.

Thank You,

Murali

As you can see the error has changed (previously it said that the xpath was null, now it says that the selector is invalid.

You don't have any quotes around the XPath (I would expect your development IDE to be sticking red lines under it highlighting the problem).

If you change it to:

WebElement element = driver.findElement(By.xpath("//*[@id='description']/div/div/div[2]/div"));

Actions action = new Actions(driver).doubleClick(element);

action.build().perform();

The code should now be valid.

That being said it's a pretty brittle XPath so you will probably have problems in the future if the structure of the page you are testing changes,

Hi Mark and Shailendra,

Yes you are right its now ok.  Thank you.

But can you explain why the .(dot) should be remove though using firebug it generate the xpath with a .(dot) ?

Cheers,

Jianah

@Jianah,

Can you try with .(dot) in xpath ?

WebElement element = driver.findElement(By.xpath(".//*[@id='description']/div/div/div[2]/div"));

Actions action = new Actions(driver).doubleClick(element);
action.build().perform();
