starts-with Function

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


          boolean starts-with(string, string)

If an argument is not of type string, it is first converted to a string using the string() function and then the result of that conversion is evaluated.

CautionCaution:
Stringconversions for node sets that are passed as arguments to this function may yield unexpected results. For more information, see string Function.

This function is case-sensitive.

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".
