starts-with Function

Returns true if the first argument string starts with the second argument string; otherwise returns false.

boolean starts-with(string, string)

Remarks

If an argument is not of type string, it is first converted to a string and then evaluated. The function is case-sensitive.

Example

The following example illustrates how to use the starts-with() function to query a collection of books whose title begins with a capital letter "W".
