Jostraca - Documentation - Examples - Replace Regular Expressions

Jostraca Example: Replace Regular Expressions example index	www.jostraca.org info@jostraca.org

Description:

This template shows how to use the @replace-regexp directive to make your template more readable. The basic idea is to replace insertions of the form <%=foo%> with the form: ${foo}, for any variable foo. Notice how the regular expression back reference $1 is used to insert the value of the submatch and how the shortcut properties $<o> and $<c> are used to escape the open and close script markers <% and %> in the @replace-regexp directive.
