|

<h3>Description</h3>
|
||||
<p>Specialization of <a href="loadresource.html">loadresource</a> that works on files exclusively
|
||||
and provides a <var>srcFile</var> attribute for convenience. Unless an <var>encoding</var> is
|
||||
specified, the encoding of the current locale is used.</p>
|
||||
<p>If the resource content is empty (maybe after processing a <code>filterchain</code>) the property
|
||||
is not set.</p>
|
||||
|
||||
<h3>Parameters</h3>

<p>The LoadFile task supports nested <a href="../Types/filterchain.html">FilterChain</a>s.</p>
|
||||
|
||||
<h3>Examples</h3>
|
||||
<p>Load file <samp>message.txt</samp> into property <code>message</code>;
|
||||
an <code><echo></code> can print this.</p>
|
||||
<pre>
|
||||
<loadfile property="message"
|
||||
srcFile="message.txt"/></pre>
|
||||
|
||||
<p>The above is identical to</p>
|
||||
<pre>
|
||||
<loadresource property="message">
|
||||
<file file="message.txt"/>
|
||||
</loadresource></pre>
|
||||
|
||||
<p>Load a file using the Latin-1 encoding</p>
|
||||
<pre>
|
||||
<loadfile property="encoded-file"
|
||||
srcFile="loadfile.xml"
|
||||
encoding="ISO-8859-1"/></pre>
|
||||
|
||||
<p>Load a file, don't fail if it is missing (a message is printed, though)</p>
|
||||
<pre>
|
||||
<loadfile property="optional.value"
|
||||
srcFile="optional.txt"
|
||||
failonerror="false"/></pre>
|
||||
|
||||
<p>Load a property which can be used as a parameter for another task (in this
|
||||
case <code>mail</code>), merging lines to ensure this happens.</p>
|
||||
<pre>
|
||||
<loadfile property="mail.recipients"
|
||||
srcFile="recipientlist.txt">
|
||||
<filterchain>
|
||||
<<a href="../Types/filterchain.html#striplinebreaks">striplinebreaks</a>/>
|
||||
</filterchain>
|
||||
</loadfile></pre>
|
||||
|
||||
<p>Load an XML file into a property, expanding all properties declared in the file in the
|
||||
process.</p>
