Hi, I am trying to get a xpath query using the xpath function lower-case or uppper-case, but they seem to not work in selenium (where I test my xpath before I apply it).
Example that does NOT work: //*[.=upper-case('some text')]
I have no problem locating the nodes I need in complex path and even using aggregated functions, as long as I don't use the upper and lower case.
Has anyone encountered this before? Does it make sense?
Thanks.
upper-case() and lower-case() are XPath 2.0 functions. Chances are your platform supports XPath 1.0 only.
Try:
translate('some text','abcdefghijklmnopqrstuvwxyz','ABCDEFGHIJKLMNOPQRSTUVWXYZ')
which is the XPath 1.0 way to do it. Unfortunately, this requires knowledge of the alphabet the text uses. For plain English, the above probably works, but if you expect accented characters, make sure you add them to the list.
If you are going to need upper case in multiple places in your xslt, you can define variables for the lower case and upper case and then use them in your translate function everywhere. It should make your xslt much cleaner.
Example at XSL/XPATH : No upper-case function in MSXML 4.0 ?
It's good to note that for the people working on XSL documents, using CSS' text properties solves transformation problems like capitalizing.
