Syntax

fn:string-length(string? $string) => integer?

Description

This function returns the length of the value of $string as integer value. If the value of $string is the empty sequence, the empty sequence is returned.

Argument

$string	string value

Example

string-length("Donaudampfschiffahrtskapitänsabzeichen")

```
string-length(normalize-space("   "))
```

The first function call returns 38, the second zero, since the string value is a zero-length string after normalizing whitespace.
