Как можно из этого массива получить такой список:

            <ul id="browser7">
                <li>NameCat_8</li>
                <li>NameCat_9</li>
                <li>NameCat_3</li>
                <li>NameCat_11</li>
                <li>NameCat_13</li>
                <li>NameCat_14</li>
                <li>
                    <span class="folder">NameCat_22</span>
                    <ul>
                        <li><a href="/">ContCat_22</a></li>
                        <li><a href="/">ContCat_22</a></li>
                        <li><a href="/">ContCat_22</a></li>
                        <li><a href="/">ContCat_22</a></li>
                        <li><a href="/">ContCat_22</a></li>
