XPath to retrieve text within span
提问by shivamsupr
I am trying to figure out the XPath which will retrieve the 'text Data 3' from the following HTML snippet
我试图找出将从以下 HTML 片段中检索“文本数据 3”的 XPath
<span class="inner-span">
Text-data 1
<br>
<span>Text Data 2</span> text Data 3
</span>
So far i have tried the following Xpath which leads me to the span with class 'inner-span'
到目前为止，我已经尝试了以下 Xpath，它使我进入了“inner-span”类的跨度
/html/body/div/div[4]/div[2]/div[2]/div/div[2]/div/span[@class="inner-span"]
But dont know what to add more to Xpath which will only give me text 'text Data 3' from above Html snippet. Thanks
但不知道要向 Xpath 添加更多内容，它只会从上面的 Html 片段中给我文本“文本数据 3”。谢谢

For your particular case this XPath query would work:
对于您的特定情况，此 XPath 查询将起作用：
normalize-space(//span[@class="inner-span"]/text()[last()])
Tried it in this online testerand here's the result:
在这个在线测试器中尝试过，结果如下：
- Your HTML;
- My XPath expression;
- The expected result "text Data 3".
- 你的 HTML；
- 我的 XPath 表达式；
- 预期结果“文本数据 3”。

You could select /html/body/div/div[4]/div[2]/div[2]/div/div[2]/div/span[@class="inner-span"]/text()[last()]to get the text node (though with leading and trailing white space) or you can use an XPath returning a string with normalize-space(/html/body/div/div[4]/div[2]/div[2]/div/div[2]/div/span[@class="inner-span"]/text()[last()]).
您可以选择/html/body/div/div[4]/div[2]/div[2]/div/div[2]/div/span[@class="inner-span"]/text()[last()]获取文本节点（尽管带有前导和尾随空格），或者您可以使用 XPath 返回带有normalize-space(/html/body/div/div[4]/div[2]/div[2]/div/div[2]/div/span[@class="inner-span"]/text()[last()]).
