XPath: How do you do a lowercase call in xpath

Question

I\'m using Firefox\'s XPath-checker and can\'t get the syntax right. I have a link:

LinkName

and I try doing:

Answer 1

You can Use Translate

//a[translate(text(), 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz') = 'linkname']

Answer 2

There is no function called lower-case in XPath 1.0 which is the version of XPath used in Firefox.

You need to use the ugly translate function instead:-

  translate(text(), 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz')

...but of course you would need to extend this if you need coverage of a wider character-set.
