How can I use XPath contains() for a few values under 1 common class?

Question

I need create a Xpath for an expression like -

(trim(STRING_1)=upper(STRING_2))

but unfortunately this expression is located in some editor, the code is -

<div class="ace_line" style="height: 16px;">
 <span class="ace_paren ace_lparen">  (  </span>
 <span class="ace_support ace_function">  trim  </span>
 <span class="ace_paren ace_lparen">  (  </span>
 <span class="ace_storage ace_type">  STRING_1  </span>
 <span class="ace_paren ace_rparen">  )  </span> 
 <span class="ace_keyword ace_operator">  =  </span> 
 <span class="ace_support ace_function">  upper  </span>
 <span class="ace_paren ace_lparen">  (  </span>
 <span class="ace_storage ace_type">  STRING_2  </span>
 <span class="ace_paren ace_rparen">  ))  </span></div>

(extra spaces for best visualization)

How can I create a Xpath for the whole expression?

It should be something like -

//*[contains(text(),'(', 'trim', '(', 'STRING_1', ')', '=', 'upper', '(', 'STRING_2', '))')]

But it doesn't work

Answer 1

You can use multiple contains() in a single XPath expression like:

"//*[contains(text(),'(') and contains(text(),'trim') and contains(text(),'STRING_1') and contains(text(),'=') and contains(text(),'upper') and contains(text(),'STRING_2') and contains(text(),')') and contains(text(),'))')]"

You can also use something like this:

"//div[.//span[contains(text(), 'trim') and .//span[contains(text(), 'upper')]]"

Answer 2

The texts trim and upper can be at any position within the <div class="ace_line"...>.

Solution

You can use the following locator strategy:

• xpath using the texts trim and upper:

  "//div[@class='ace_line'][.//span[contains(., 'trim')]][.//span[contains(., 'upper')]]"
  

• xpath ignoring the case of STRING_1:

  "//div[contains(translate(., 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'STRING_1')]"
  

• xpath ignoring the case of STRING_1 and STRING_2:

  "//div[contains(translate(., 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'STRING_1')][contains(translate(., 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'STRING_2')]"
