<h2><a name="loadproperties">LoadProperties</a></h2>
<h3>Description</h3>
<p>
Load a file's contents as Ant properties.  This is equivalent
to <code>&lt;property file|resource=&quot;...&quot;/&gt;</code> except that it
supports nested <code>&lt;filterchain&gt;</code> elements.
Also if the file is missing, the build is halted with an error, rather
than a warning being printed.
</p>

<p>If you want to simulate <a href="property.html">property</a>'s
prefix attribute, please use <a
href="../CoreTypes/filterchain.html#prefixlines">prefixlines</a>
filter.</p>
