RE: Count number of files in fileset

[Dick, Brian E.]

Where is ${toString:} documented? Are there any other pseudo-properties?

In 1.6 you could use the ${toString:} psuedo-property:
  <target name="present">
    <fileset id="fileset.notpresent" dir="."
             includes="*.notpresent"/>
    <condition property="no.files.present">
      <equals arg1="" arg2="${toString:fileset.notpresent}"/>
    </condition>
    <echo>no.files.present=${no.files.present}</echo>
    <fileset id="fileset.present" dir="."
             includes="*.xml"/>
    <condition property="no.files.present_2">
      <equals arg1="" arg2="${toString:fileset.present}"/>
    </condition>
    <echo>no.files.present_2=${no.files.present_2}</echo>
  </target>

No, this is not true in this case. The <header> and <footer> elements 
are independent
of the fileset.
