<project xmlns:fl="antlib:it.haefelinger.flaka">

  <property name="digitA" value="42"/>
  <property name="digitB" value="23"/>
  <property name="wordA"  value="abcd"/>
  <property name="wordB"  value="efgh"/>

  <!-- compare of digits -->
  <fl:when test=" '${digitA}' > '${digitB}' ">
    <echo>${digitA} gt ${digitB}</echo>
  </fl:when>

  <!-- example with string compare in switch -->
  <fl:switch value="${wordA}">
    <cmp gt="${wordB}">
      <echo>${wordA} gt ${wordB}</echo>
    </cmp>
    <cmp lt="${wordB}">
    <echo>${wordA} lt ${wordB}</echo>
    </cmp>
  </fl:switch>
