   Click     //span[@ant-select-selection-placeholder">Select Source(s)"]

Error

Error: locator.click: DOMException: Failed to execute 'evaluate' on 'Document': The string './/span[@ant-select-selection-placeholder">Select Source(s)"]' is not a valid XPath expression.

CodePudding user response：

Please correct your Xpath from

//span[@ant-select-selection-placeholder">Select Source(s)"]

to

//span[@]

Or

//span[@ and (text()="Select Source(s)")]

CodePudding user response：

This error message...

Error: locator.click: DOMException: Failed to execute 'evaluate' on 'Document': The string './/span[@ant-select-selection-placeholder">Select Source(s)"]' is not a valid XPath expression.

...implies that the XPath you have used isn't a valid xpath expression.

You have to make two minor adjustments as follows:

• The value of the class attribute must be within single double quotes i.e. "value"
• Select Source(s) is the innerText within, so you have to mention it as text.

Solution

You can use either of the following Locator Strategies:

• xpath 1:

  //span[@class='ant-select-selection-placeholder' and starts-with(., 'Select Source')]
  

• xpath 2:

  //span[@class='ant-select-selection-placeholder' and contains(., 'Select Source')]
  

CodePudding user response：

Please use below xpath

//span[contains(@class,'ant-select-selection-placeholder') and contains(text(),'Select Source(s)')]

or

//span[contains(@class,'ant-select-selection-placeholder') and starts-with(text(),'Select Source')]

Please check in the dev tools (Google chrome) if we have unique entry in HTML DOM or not.

Steps to check:

Press F12 in Chrome -> go to element section -> do a CTRL F -> then paste the xpath and see, if your desired element is getting highlighted with 1/1 matching node.

If we have 1/1 matching node, Please make sure that :

1. This div is not under an iframe.
2. This div is not under a shadow-root.
3. You should not be on new tab/windows launched by selenium.
