concat
Concatenates (appends) two or more values into a single result string. All input values are automatically converted to type "string". By default, this function has only two parameters, but you can add more. Click Add parameter ( 
) or Delete parameter ( 
) to add or remove parameters.
| Note: | All the inputs to the concat function must have a value. If any of the inputs does not have a value, the function is not called and an error occurs. Be aware that an empty string is a valid input value; however, an empty sequence (such as the result of the set-empty function) is not a valid value and the function will fail as a result. To prevent this from happening, you can first process values with the substitute-missing function and then supply the result as input to the concat function. |
Languages
Built-in, C++, C#, Java, XQuery, XSLT 1.0, XSLT 2.0, XSLT 3.0.
