I have a problem finding elements in XPath that\'s contains a certain string ignoring character casing.
I want to find in a HTML page all the nodes with id contains
Not sure if you've tried this yet, but this is what I do for case sensitive contains searches:
//*[contains(translate(./@id,'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz'), 'footer')]/@id
I saw you have found your solution, so I'm posting this answer in case others have the same issue.
