This does not work in Chrome Developer tools to locate a element, i am looking to locate the 'Submit' button in the screen

//input[matches(@value,'submit','i')]

However, using 'translate' to replace all caps to small works as below

//input[translate(@value,'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz') = 'submit']

Update: I just found the reason why 'matches' doesnt work. I am using Chrome with xpath 1.0 which wont understand the syntax 'matches'. It should be xpath 2.0

You mentioned that PHP solutions were acceptable  and PHP does offer a way to accomplish this even though it only supports XPath v1 0  You can extend the XPath support to allow PHP function calls    xpathObj   new DOMXPath  docObj    xpathObj- gt registerNamespace  php   http   php net xpath        required   xpathObj- gt registerPhpFunctions  strtolower        leave empty to allow  any  PHP function   xpathObj- gt query    CD php functionString  strtolower   title     empire burlesque        See the PHP registerPhpFunctions documentation for more examples  It basically demonstrates that  php function  is for boolean evaluation and  php functionString  is for string evaluation

XPath 2 has a lower-case  and upper-case  string function   That s not quite the same as case-insensitive  but hopefully it will be close enough     CD lower-case  title   empire burlesque     If you are using XPath 1  there is a hack using translate
