How to use count() function in xpath of selenium?

Using findElements() and size() methods we can get the count. But I want to extract the count using count() function in the xpath.

Will the count function return an integer value?

Suppose, My xpath is (//input[@id='stack'])[3] and there are 3 matching nodes with //input[@name='hai']

Can I modify my xpath like below?

(//input[@id='stack'])[count(//input[@name=''hai])]

driver.findElements() returns a List of WebElements, and .size() returns the integer size of a list, so I think youd be better off doing the following:

int myCount = driver.findElements(By.xpath("<Your Xpath Here>")).size();

This will get you the count of elements on your page that match your xpath input

Yes, if

count(//input[@name='hai'])

evaluates to 

3

then

(//input[@id='stack'])[count(//input[@name='hai'])]

will select the same nodes as 

(//input[@id='stack'])[3]

would select.

However, your intent is quite unclear, especially given that

  • //input[@id='stack'] will select all of the input elements with an id attribute value of 'stack'. Usually id attribute values are unique across the document, so usually this would select only a single element.

  • (//input[@id='stack'])[count(//input[@name='hai'])] assumes that there are at least as many input elements id'ed as 'stack' as there are input elements named 'hai' -- an odd assumption.
