People posting questions so often make this mistake. The fact that you don't
understand an error message doesn't mean that no-one else does!

This error message makes it pretty clear that the XPath parser has tried to
interpret if() as a function call, which means it isn't aware of the XPath
2.0 if() then else syntax.
