ncmp Function

Performs case-insensitive comparison of two string values.

This function returns:

• negative number– indicates that the value of the first argument is lexically less than the second

• positive number– indicates that the first argument is lexically greater than the second

• 0 (zero) – indicates that the arguments are equal

Arguments are coerced to strings, if necessary.

Example

The following expression returns 0.

<ncmp>
   <s>Daryl</s>
   <s>daryl</s>
</ncmp>
