<h2><a name="loadresource">LoadResource</a></h2>
<h3>Description</h3>
<p>
Load a text resource into a single property. Unless an encoding is
specified, the encoding of the current locale is used. Resources to
load are specified as nested <a

element resource collections.
</p>

<h3>Parameters</h3>

The LoadResource task supports nested <a href="../CoreTypes/filterchain.html">

<h3>Examples</h3>

&lt;loadresource property="homepage"&gt;
&lt;url url="http://ant.apache.org/index.html"/&gt;

Load the entry point of Ant's homepage into property "homepage"; an
