Counter

XTP pages can use the counter just by adding the tag:

A counter example: <ct:counter id='test'/>

Here the patterns to do it. For efficiency, we've added the cache directive. The cache directive tells XTP to execute the stylesheet only once and cache the generated JSP file.

default.xsl

<#@ cache #> counter[@id] << <%= application.attribute["<{@id}>"] %> >> counter << <%= application.attribute.counter++ %> >>

JSP flow control

• ct:get prints the value of a variable
• ct:if generates an if statement
• ct:iter loops

ct:get <<
<%= <{@expr}> %>
>>

ct:if <<
<% if (<{@expr}>) { %>
  <xsl:apply-templates/>
<% } %>
>>

ct:iter[@index] <<
<% for (var <{@index}> in <{@expr}>) { %>
  <xsl:apply-templates/>
<% } %>
>>

ct:iter <<
<% for (var i in <{@expr}>) { %>
  <xsl:apply-templates/>
<% } %>
>>
