Hello everyone, the essence of the voros, you need to parse the elements of the table, only there is a class with a specific name in one of the cells of the table:

<body>
    <div class="content">
        <table class="normal">
            <tbody>
                <tr>
                    <td class="name">Hello</td>
                    <td></td>
                    <td></td>
                    <td class="count"></td>
                    <td></td>
                    <td class="parse this"></td>
                    <td class="parse this"></td>
                    <td class="parse this"></td>
                    <td></td>
                    <td></td>
                    <td></td>
                </tr>
                <tr>
                    <td class="name">Hello</td>
                    <td></td>
                    <td></td>
                    <td class="count"></td>
                    <td></td>
                    <td></td>
                    <td class="parse this"></td>
                    <td class="parse this"></td>
                    <td></td>
                    <td></td>
                    <td></td>
                </tr>
                <tr>
                    <td class="name">Hello</td>
                    <td></td>
                    <td></td>
                    <td class="count"></td>
                    <td></td>
                    <td class="parse this"></td>
                    <td></td>
                    <td class="parse this"></td>
                    <td></td>
                    <td></td>
                    <td></td>
                </tr>
                <tr>
                    <td class="name">Hello</td>
                    <td></td>
                    <td></td>
                    <td class="count"></td>
                    <td></td>
                    <td></td>
                    <td></td>
                    <td></td>
                    <td></td>
                    <td></td>
                    <td></td>
                </tr>
                <tr>
                    <td class="name">Hello</td>
                    <td></td>
                    <td></td>
                    <td class="count"></td>
                    <td></td>
                    <td></td>
                    <td></td>
                    <td></td>
                    <td></td>
                    <td></td>
                    <td></td>
                </tr>

Good afternoon.
If Nokogiri knows how to use xpath, then this is how you get all name
By analogy, you will find count. Xpath rules.
