XML Syntax

Control Structures

if

Inserts the content of the <if> element if the EPScript in the test attribute returns true.

<if test="date_effective">(<print expr="date_effective" opts="res=year" />)</if>

choose/when/otherwise

A <choose> element consists of one or many <when> elements and an optional <otherwise> element. The test attribute of each <when> element is evaluated, and if this returns true the content is included and execution leaves the <choose> structure. If no test attribute returns true and an <otherwise> element is provided, the content of the <otherwise> element is included.

<choose>
  <when test="title"><print expr="title" /></ep:when>
  <otherwise><print expr="type" /> #<print expr="eprintid" /></otherwise>
</choose>

Procedures

print

Outputs the result of the provided expression attribute as a string. If the result is boolean, TRUE or FALSE will be produced.

<print expr="isbn" />

phrase

<phrase ref="my_phrase"><param name="my_pin">Pin Value</param></phrase>
