如何通过xpath text()和该元素的第二个表亲找到一个元素?

问题描述

我在Java中使用Htmlunit.我需要通过text()找到一个元素，并且我需要这个元素的第二个表亲(我认为).

I use Htmlunit in java. I need to find an element by text(), and i need the second cousin of this element (i think).

我尝试过:

HtmlElement element = page.getFirstByXPath("//*[text() = \"SOMETHING\"]/parent/following-sibling/child");
System.out.println(element.asText()); // it's null

更新:html源页面:

Update:The html source page:

<tr>
    <script>
    _l('its not important')
    </script>
    <td valign="top">
        <font class="its not important">
    </td>
    <td valign="top">
        <font class="its not important">
            SOMETHING
            <script>
                _l('its not important')
            </script>
        </font>
        <script>
            _l('its not important')
        </script>
    </td>
</tr>
<tr>
    <td></td>
    <td valign="top">
        THE INFORMATION I NEED
    </td>
</tr>

推荐答案

以下XPath应该有效:

The following XPath should work:

//tr[td/*[contains(text(), "SOMETHING")]]/following-sibling::tr/td[@valign ="top"]

它将选择一个<tr>元素，该元素确实具有带有所需文本的孙子元素.然后它将选择所有后续的同级并选择下一个元素.请注意，我基于valign属性值选择了正确的<td>元素c，您可能不想这样做，而是使用位置，即td[2]

It will select a <tr> element, which does have a grandchild with the required text. Then it will select all following siblings and select the next element. Please note that I selected the correct <td> element basec on the valign attribute value, you might not want to do that and instead use the position, i.e. td[2]
