    <title>Ant-contrib Tasks: Foreach</title>
  </head>

  <body>
    <h1>Foreach</h1>

    <p>The foreach task iterates over a list, a list of paths, or
    both.  If both, list and paths, are specified, the list will be
    evaluated first.  Nested paths are evaluated in the order they
    appear in the task.</p>

    <h2>Parameters</h2>
    <table border="1" cellpadding="2" cellspacing="0">
      <tr>
        <th>Attribute</th>
        <th>Description</th>
        <th>Required</th>
      </tr>
      <tr>
        <td valign="top">list</td>
        <td valign="top">The list of values to process, with the
        delimiter character, indicated by the &quot;delimiter&quot;
        attribute, separating each value.</td>
        <td align="center" valign="top">Yes, unless a nested Fileset
        has been specified.</td>
      </tr>
      <tr>
        <td valign="top">target</td>
        <td valign="top">Name of the target to call for each token or
        matched file.</td>
        <td align="center" valign="top">Yes</td>
      </tr>
      <tr>
        <td valign="top">param</td>
        <td valign="top">Name of the parameter to pass the tokens or
        files in as to the target.</td>
        <td align="center" valign="top">Yes</td>
      </tr>
      <tr>
        <td valign="top">delimiter</td>
        <td valign="top">The delimiter characters that separates the
        values in the &quot;list&quot; attribute.  Each character in the
        supplied string can act as a delimiter.  This follows the semantics
        of the StringTokenizer class.</td>
        <td align="center" valign="top">No, defaults to &quot;,&quot;.</td>
      </tr>
      <tr>
        <td valign="top">inheritall</td>
        <td valign="top">If <code>true</code>, pass all properties to
        the called target.  Defaults to <code>false</code>.</td>

      </tr>
      <tr>
        <td valign="top">inheritrefs</td>
        <td valign="top">If <code>true</code>, pass all references to the
        the called target.  Defaults to <code>false</code>.</td>
        <td align="center" valign="top">No</td>
      </tr>
      <tr>
        <td valign="top">parallel</td>
        <td valign="top">If <code>true</code>, all instances of the called
        target will execute in parallel.  Defaults to <code>false</code>,
        which forces sequential execution of the targets.  It is up to
        the caller to ensure that parallel execution is safe.  This is
        accomplished through the means of the "parallel" task contained
        in the ANT core.</td>
        <td align="center" valign="top">No</td>
      </tr>
      <tr>
        <td valign="top">maxThreads</td>
        <td valign="top">The maximum number of allowable threads when executing
            in parallel.</td>
        <td align="center" valign="top">No. Defaults to 5.</td>
      </tr>
      <tr>
        <td valign="top">trim</td>
        <td valign="top">If <code>true</code>, any leading or trailing
        whitespace will be removed from the list item before it is passed
        to the requested target
        </td>
        <td align="center" valign="top">No. Defaults to false.</td>
      </tr>

    <h2>Parameters specified as nested elements</h2>

    <a name="path"><h3>path</h3></a>

    <p><a href="http://ant.apache.org/manual/using.html#path">Path</a>s
    are used to select sets of files or directories to iterate over.</p>

    <p>Using a path allows you to determine the order by which files
    are considered by using
    <a href="http://ant.apache.org/manual/CoreTypes/filelist.html">filelist</a>s
    or explicit <code>pathelements</code>.  You also can specify
    whether you want to iterate over files or directories by chosing
    either filesets or
    <a href="http://ant.apache.org/manual/CoreTypes/dirset.html">dirset</a>s.</p>

    <a name="fileset"><h3>fileset</h3></a>

    <p><a href="http://ant.apache.org/manual/CoreTypes/fileset.html">FileSet</a>s
    are used to select sets of files to iterate over.  <strong>This
    element is deprecated, use <a href="#path">nested path elements</a>
    instead.</strong></p>

    <h3>param</h3>

    <p>Specifies the properties to set before running the specified
    target. See <a href="http://ant.apache.org/manual/CoreTasks/property.html">property</a>
    for usage guidelines.</p>

    <h3><a name="reference">reference</a></h3>

    <p>Used to chose references that shall be copied into the new
    project, optionally changing their id.</p>

    <table border="1" cellpadding="2" cellspacing="0">
      <tr>
        <th>Attribute</th>
        <th>Description</th>
        <th>Required</th>
      </tr>
      <tr>
        <td valign="top">refid</td>
        <td valign="top">The id of the reference in the calling project.</td>
        <td valign="top" align="center">Yes</td>
      </tr>
      <tr>
        <td valign="top">torefid</td>
        <td valign="top">The id of the reference in the called project.</td>
