1 Introduction

The function split() is used to break down the value of a complex string variable into individual elements which can then be treated individually.

This allows you to iterate through complex string values, e.g., in a loop. Elements are broken down according to a specified pattern which serves as separator.

2 Syntax

split(<string variable>, <pattern>)


<pattern> may be a regular expression to find multiple separators (e.g., comma and semicolon) and complex separators (e.g., ---) at once.

To use a control character that is reserved in RegExp, e.g., the pipe symbol (|), as a separator, you have to double escape the character. For example:

#split(fo|o, '\\|')#


3 Example

In the following example, the string value of variable foo is broken down into individual elements. Elements are separated by a comma. Each element (except the last) is then printed with a following <br> tag:

<isset scope="request" name="lines" value="#split(foo, ',')#">
<isloop iterator="lines" alias="line">
  <isprint value="#line#">
  <isif condition="#hasNext(line)#"><br></isif>
