Question

我想删除<td>元素中的空格。在这个元素中，我有几个<span>元素，它们之间是不必要的空格。有没有办法删除它们而不删除<span>元素中的空格？

我没有可能在代码中删除它们，我将通过使用css或更改PHP输出来处理它们。

我有以下想法，但它删除了（当然）所有空格：

echo str_replace(' ', '', $total['value']);

我也尝试过CSS方法：

white-space: pre-line

但是这会在每个空间增加一条线......

还有其他想法吗？

修改这就是我所拥有的：

<td class="totals totals_amount_order_total">
                                <span class="woocommerce-Price-amount amount"><span class="woocommerce-Price-currencySymbol">€</span>&nbsp;636,17</span>
                                <br class="wgm-break">
                                <span class="wgm-tax includes_tax">EnthÃ¤lt<span class="amount"><span class="woocommerce-Price-amount amount"><span class="woocommerce-Price-currencySymbol">€</span>&nbsp;101,57</span></span> MwSt. (19%)</span>
                          </td>

我现在要删除标记之间的所有空格（但不删除标记内的文本）：

<td class="totals totals_amount_order_total"><span class="woocommerce-Price-amount amount"><span class="woocommerce-Price-currencySymbol">€</span>&nbsp;636,17</span><br class="wgm-break"><span class="wgm-tax includes_tax">EnthÃ¤lt<span class="amount"><span class="woocommerce-Price-amount amount"><span class="woocommerce-Price-currencySymbol">€</span>&nbsp;101,57</span</span> MwSt. (19%)</span></td>

编辑2：我试图用它们之前的空格替换所有<span>标记。我尝试使用preg_replace执行此操作，但我不确定如何为范围内的不同类设置通配符

Answer 1

$new = preg_replace('/>\s*</','><',$orig);

适合我！从您的示例输入和输出中，我注意到您只删除了标记之间的空格。

我的测试中的完整代码：

    $orig="<td class=\"totals totals_amount_order_total\">
                            <span class=\"woocommerce-Price-amount amount\"><span class=\"woocommerce-Price-currencySymbol\">€</span>&nbsp;636,17</span>
                            <br class=\"wgm-break\">
                            <span class=\"wgm-tax includes_tax\">EnthÃ¤lt<span class=\"amount\"><span class=\"woocommerce-Price-amount amount\"><span class=\"woocommerce-Price-currencySymbol\">€</span>&nbsp;101,57</span></span> MwSt. (19%)</span>
                      </td>";

    $new = preg_replace('/>\s*</','><',$orig);
    print($new);

我得到了这个（查看来源）：

 <td class="totals totals_amount_order_total"><span class="woocommerce-Price-amount amount"><span class="woocommerce-Price-currencySymbol">€</span>&nbsp;636,17</span><br class="wgm-break"><span class="wgm-tax includes_tax">EnthÃ¤lt<span class="amount"><span class="woocommerce-Price-amount amount"><span class="woocommerce-Price-currencySymbol">€</span>&nbsp;101,57</span></span> MwSt. (19%)</span></td>

删除空格，但仅在<span>元素之外
