XML String-join()
The string-join() function is used to join a sequence of strings into a single string by placing a separator between each string.
Syntax
The syntax for the string-join() function is:
string-join(sequence, separator)
Example
Suppose we have a sequence of strings:
let $colors := ('red', 'green', 'blue')
We can use string-join() to join these strings with a comma and a space separator:
string-join($colors, ', ')
Output
The output of the above example will be:
'red, green, blue'
Explanation
The string-join() function takes two arguments - a sequence of strings and a separator. It joins the strings in the sequence together into a single string, separating each string with the provided separator.
In the example above, the strings 'red', 'green', and 'blue' are joined together with a comma and a space separator.
Use
The string-join() function is useful when working with sequences of strings that need to be combined into a single string. This can be useful when formatting output or constructing URLs, among other things.
Important Points
- The sequence argument must be a sequence of strings.
- The separator argument must be a string.
Summary
The string-join() function is used to join a sequence of strings into a single string by placing a separator between each string. It takes two arguments - a sequence of strings and a separator - and returns a single string that has each element of the sequence separated by the given separator. This function can be used for formatting output or constructing URLs, among other things.
