无法使用Java中的Selenium捕获文本

我正在使用Java中的Selenium从以下代码段中捕获值。但这是返回无效的值。

<div class="selenium" style="max-height: 0px !important; max-width: 0px !important;">
<div class="share metric">
<span id="nsf" class="nsf">
"2.2210636079249215+2.224479431183342+2.2244191794364805+2.2635962763351296+2.289855072463768+2.3309352517985613+2.3216783216783217+2.360018509949098+null+2.042235790730032+0.000006222369997702123+0</span></div>

我尝试使用

driver.findElement(By.xpath("//div[@class='share metric']/span[@id='nsf']")).getAttribute("value")

并

driver.findElement(By.xpath("//div[@class='share metric']/span[@id='nsf']")).gettext()

I am using Selenium in Java to capture values from the below code snippet. But it's returning a null value.

<div class="selenium" style="max-height: 0px !important; max-width: 0px !important;">
<div class="share metric">
<span id="nsf" class="nsf">
"2.2210636079249215+2.224479431183342+2.2244191794364805+2.2635962763351296+2.289855072463768+2.3309352517985613+2.3216783216783217+2.360018509949098+null+2.042235790730032+0.000006222369997702123+0</span></div>

I tried using

driver.findElement(By.xpath("//div[@class='share metric']/span[@id='nsf']")).getAttribute("value")

and

driver.findElement(By.xpath("//div[@class='share metric']/span[@id='nsf']")).gettext()

您的XPath是错误的，跨度标签不是＆lt; div class =“ share Metric”＆gt;的孩子。

为什么完全使用XPATH？通过其ID局部局部局部效果很好。

代码：

    WebElement nsf = driver.findElement(By.id("nsf"));
    String text = nsf.getText();
    System.out.println(text);

输出：

Your xpath is wrong, the span tag is not a child of <div class="share metric">.

Why using xpath at all? Localting the element by it's id works just fine.

code:

    WebElement nsf = driver.findElement(By.id("nsf"));
    String text = nsf.getText();
    System.out.println(text);

output:
