public class SplitTag

extends javax.servlet.jsp.tagext.BodyTagSupport

JSP Tag split, used to implement a perl style split on the text.

The body of the tag iterates through each string generated from the split. The normal <jsp:getProperty/> can be used to get the value of each string split out using the id of the split tag script variable.

The attribute text must be set to the id of a text tag.

By default, the split is done on whitespace. Set the optional attribute regexp to the id of a regexp tag script variable id to perform the split using a custom regular expression.

You can set the optional tag attribute limit to the number of items you want to limit the split to.
