Deserializing a Bean from XML</h3>
See also <a href="../java.beans/WriteXml.html" class="eglink"><font size="-1"><b>e7</b> Serializing a Bean to XML</font></a>.
<pre>
// Deserialize an object
try {
XMLDecoder decoder = new XMLDecoder(new BufferedInputStream(
new FileInputStream(<font color="#0066ff"><i>"infilename.xml"</i></font>)));
// MyClass is declared in <a href="../java.beans/WriteXml.html" class="eglink"><font size="-1"><b>e7</b> Serializing a Bean to XML</font></a>
<font color="#0066ff"><i>MyClass</i></font> o = (<font color="#0066ff"><i>MyClass</i></font>)decoder.readObject();
decoder.close();
// Use the object
int prop = o.getProp(); // 1
int[] props = o.getProps(); // [1, 2, 3]
} catch (FileNotFoundException e) {
}
</pre>
Here is the XML data being deserialized:
<pre>
<?xml version="1.0" encoding="UTF-8"?>
<java version="1.4.0" class="java.beans.XMLDecoder">
<object class="MyClass">
<void property="prop">
<int>1</int>
</void>
<void property="props">
<array class="int" length="3">
<void index="0">
<int>1</int>
</void>
<void index="1">
<int>2</int>
</void>
<void index="2">
<int>3</int>
</void>
</array>
