关于XML反序列化

Question

这是关于XML反序列化的一个非常简单的问题。

我这里有一个简单的XML（部分，为了使这个问题变小）

<iqu>
    </items>
        <item>
            <installedsize></installedsize>
            <softwareid>58907ba6-538b-424a-bfe4-98391857b1b1</softwareid>
            <active>1</active>
            <installdate>2013-06-03T21:02:07</installdate>
            <installdisplaydate>Jun 3, 2013 9:02 PM</installdisplaydate>
            <currentstate>0</currentstate>
            <isinstalled>true</isinstalled>
            <uninstallkeys>
                <key type="software">
                    <![CDATA[Pidgin]]>
                </key>
            </uninstallkeys>
        </item>
    </items>
</iqu>

我已经为反序列化做了一个类对象

using GalaSoft.MvvmLight;

                {
                    if (_uninstallinfo != value)
                    {
                        _uninstallinfo = value;
                        base.RaisePropertyChanged("uninstallinfo");
                    }
                }
            }
        }
    }
}

这里的问题是关于我向你展示的XML中的这个节点（上图）

<uninstallkeys>
    <key type="software">
        <![CDATA[Pidgin]]>
    </key>
</uninstallkeys>

反序列化这部分的正确方法是什么？
