<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>
<h3>Parameters</h3>
<table border="1" cellpadding="2" cellspacing="0">

<p>
The LoadProperties task supports nested <a href="../CoreTypes/filterchain.html">
FilterChain</a>s, as well as a nested <code>&lt;classpath&gt;</code>
element for use with the <i>resource</i> attribute.
<h3>Examples</h3>
<pre> &lt;loadproperties srcFile="file.properties"/&gt;
</pre>
Load contents of file.properties as Ant properties.
<pre> &lt;loadproperties srcFile="file.properties"&gt;
&lt;filterchain&gt;
&lt;<a href="../CoreTypes/filterchain.html#linecontains">linecontains</a>&gt;
&lt;contains value=&quot;import.&quot;/&gt;
&lt;/linecontains&gt;
&lt;/filterchain&gt;
&lt;/loadproperties&gt;
</pre>
Read the lines that contain the string &quot;import.&quot;
from the file &quot;file.properties&quot; and load them as
Ant properties.
