number of elements chosen for an xpath query using the chrome console

Is there a way to find the number of nodes selected with an xpath in the Chrome console?

I managed to select a group of nodes using the xpath:

$x("//*[@rel='noopener noreferrer']")

in the Chrome console. However, I am unable to determine the count of nodes selected using the count function in Chrome with:

$x(count("//*[@rel='noopener noreferrer']"))

Interestingly, the count function works fine in Firefox using:

(//*[@rel='noopener noreferrer'])

If anyone could assist me in obtaining the count using the Chrome console, it would be greatly appreciated.

Answer №1

Utilizing xPath can provide you with a direct count =) 

count(locator)

For instance

count(//*) - counting all elements on the page - $x("count(//*)")

count(//a) - counting all a attributes on the page - $x("count(//a)")

By using console $x:

$x("//a").length

Your locator is nearly accurate

error - 

$x(count("//*[@rel='noopener noreferrer']"))

The issue here is that count() belongs to xPath, not a js function, so it should be enclosed in quotes:

fixed - 

$x("count(//*[@rel='noopener noreferrer'])")

Answer №2

$x("//*[contains(@target, '_blank') and contains(@rel, 'noopener')]").length

In this code snippet, the $x() function is used to return an array of nodes that match the specified XPath selector. By then accessing the native length property of the array, we can easily determine the number of matching nodes.

The selector 

contains(@target, '_blank') and contains(@rel, 'noreferrer')
ensures that the query is not dependent on the order in which the attributes appear in the document.
