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:

<a>LinkName</a> 

and I try doing:

//a[lower-case(child::text())='linkname'] 

but I have a syntax error. What am I doing wrong?

Thanks

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.
