case insensitive xpath contains() possible ?

Case insensitive xpath contains():

/html/body//text()[
  contains(
    translate(., 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'),
    'test'
)
]

     If the users can do, then mark the portions of text that interest us with some other means, like enclosing them in a <span> which has a cassertive class.

If it is not possible, then we can have JavaScript that help with building an correct XPath expression,

function xpathPrepare(xpath, searchString) {
  return xpath.replace("$u", searchString.toUpperCase())
          .replace("$l", searchString.toLowerCase())
          .replace("$s", searchString.toLowerCase());
}
xp = xpathPrepare("//text()[contains(translate(., '$u', '$l'), '$s')]", "Test");
// -> "//text()[contains(translate(., 'TEST', 'test'), 'test')]"

     Try the below code for case sensitive xpath contain() method,

/html/body//text()[contains(translate(., 'TES', 'tes'), 'test')]

Solution for XPath 2.0:

• Use lower-case():

/html/body//text()[contains(lower-case(.),'test')]

• Use matches() regex matching with its case-insensitive flag:

/html/body//text()[matches(.,'test', 'i')]

/html/body//text()[contains(translate(.,
‘ABCDEFGHIJKLMNOPQRSTUVWXYZ’,
‘abcdefghijklmnopqrstuvwxyz’),
‘test’)]

/html/body//text()[
  contains(
    translate(., 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'),
    'test'
  )
]

/html/body//text()[contains(translate(., 
                                      'ABCDEFGHIJKLMNOPQRSTUVWXYZ',
                                      'abcdefghijklmnopqrstuvwxyz'),
                   'test')]

if the id value is lowercase.

I am not going to use the translate() or match() xpath functions for it because you need to apply them to every element value.

Instead, I will create a custom locator class which extends the By class.

The custom locator implements both the findElement() and findElements() methods.

Both methods work in a similar way:

• check if there are elements matched by the lowercase locator; if there are, return either the first of them or the whole list
• check if there are elements matched by the uppercase locator; if there are, return either the first of them or the whole list

The custom locator class works for simple xpath expressions with only 1 text value.

It can be changed though for more than 1 value
