text() function in Xpath is case sensitive

Hi is there a simple way to make this **text()** function not case sensitive?
The workaround I found it to use

> text()[ contains( translate(., 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'test')]

instead of

> text()[contains(.,'test')]

It is pretty annoying, and the input needs to be in lowercase.

The issue provides only the two XPath text() expressions and no file or test location. Start by locating where XPath expressions are handled in the PHP backend, then determine whether case-insensitive matching is supported there; done means the requested matching works without requiring lowercase input and is covered by an appropriate test.
