基于父母兄弟姐妹的多个标准

Question

我想知道我是否可以同时将寻找某个类的前一个同级与某个文本的同级，同时将同一级别的同级与某个文本的同级组合在一起。

例如，我想找到以下单元格：

<td class="sdawatt_booknow"><a href="#" onclick="wa_class_book(160832)">Book</a></td>

通过查找包含文本的类sdawatt_hrdcell的同级Spin前面是类sdawatt_banner的TD和文本Monday - 16 September 2013。

或以下 td：

    <td class="sdawatt_booknow"><a href="#" onclick="wa_class_book(160864)">Book</a></td>

如果我们寻找"星期五 - 2013 年 9 月 13 日"的日期。

这在 Xpath 中可行吗？

<table cellspacing="0" cellpadding="0" border="0" style="border-collapse:collapse;" class="sdawatt_outer">
    <tbody><tr>
        <td class="sdawatt_hdrcell">Time</td>

Answer 1

//tr[
        contains(
            td[@class="sdawatt_banner"],
            "Monday - 16 September 2013")
    ]
    /following-sibling::tr[
                           contains(
                               td[@class="sdawatt_classname"],
                               "Spin")
                          ]/td[@class="sdawatt_booknow"]
