 I want to see if the value of an attribute or element is a number or string. I tried using number(@value) != 'NaN', but it always returns false. How can I find if a value is a string or number. The following will be true if the value is a number: test="@value <= 0 or @value > 0" The use of < and > will coerce the argument to a number, and NaN does not pass either test. If the entire test results in false, then it must not have been a number, otherwise one of the two would have been true if it were a number. I hope this helps. ................... Ken
