WebElements 列表中的相对 Xpath

在我收集了 WebElements 列表之后，是否可以使用相对 xpath？如果是这样，最好的方法是什么？

这就是我所拥有的：

List <WebElement> rows = driver.findElements(By.xpath(rowsXpath));
int j = 1;
boolean foundCollector = false;
for(WebElement e : rows) {
    String c = e.findElement(By.xpath("(//tbody)[" + j + "]//u[text()=\"" + collector + "\"])")).getText();
    if(c.equals(collector)) {
        foundCollector = true;
        break;
    }
    ++j;
}

列表行包含具有多个列的单个行，我正在尝试查找在列中包含特定名称的行。在我的for循环中，我试图使用相对xpath来查找元素，这甚至可能吗？或者，我是否需要提供用于查找行的整个 xpath 以及各个 div 的附加 xpath？

我不能保证列的顺序，这就是为什么我必须这样做的原因。

这是我用来获取行的 xpath：

String rowsXpath = "//div[@id=\"QosDashpardPanelBottom\"]//div[@id=\"CollectorQoSPerformanceMetricsgrid\"]//div[contains(@class, \"x-grid3-row  x-unselectable-single\")]";

下面是 HTML：

答案 1

是的，这绝对是可能的。请参阅此内容：

// Find the outer element.
WebElement outer = driver.findElement(By.anything("whatever"));

// This doesn't work, it searches the whole page for the XPath expression.
WebElement inner = outer.findElement(By.xpath("//some/nasty/xpath"));

// This works! It takes the outer element as root.
WebElement inner = outer.findElement(By.xpath(".//some/nasty/xpath"));

因此，如果我很好地理解了您的需求，那么您的 XPath 表达式需要如下所示：

By.xpath("(.//tbody)[" + j + "]//div[text()=\"" + collector + "\"])")

编辑（天哪，这是很多HTML，实际上只需要一小部分:)。

现在我抓住了你所追求的东西，我认为你根本不需要这种方法。请尝试以下操作：

WebElement row = driver.findElement(By.xpath("id('CollectorQoSPerformanceMetricsgrid')//div[contains(@class,'x-grid3-row x-unselectable-single') and .//u[text()='" + collector + "']]"));

只有 XPath 表达式：

id('CollectorQoSPerformanceMetricsgrid')
    //div[contains(@class,'x-grid3-row x-unselectable-single')
          and .//u[text()='" + collector + "'] ]

拆开：

FIND ELEM WITH ID = 'CollectorQoSPerformanceMetricsgrid'
id('CollectorQoSPerformanceMetricsgrid')
    FIND ALL DIV ELEMS THAT CONTAIN 'x-grid3-row x-unselectable-single' IN @CLASS
    //div[contains(@class,'x-grid3-row x-unselectable-single')
          AND HAVE AN <U> DESCENDANT WITH TEXT EQUAL TO collector VARIABLE
          and .//u[text()='" + collector + "'] ]

这将仅使用单个命令找到所需的单行。

如果您想坚持使用当前的解决方案，请尝试：

String rowsXpath = "id('CollectorQoSPerformanceMetricsgrid')//div[contains(@class, 'x-grid3-row x-unselectable-single')]";
List<WebElement> rows = driver.findElements(By.xpath(rowsXpath));
boolean foundCollector = false;
for(WebElement row : rows) {
    if(!row.findElements(By.xpath(".//u[text()='" + collector + "']")).isEmpty()) {
        foundCollector = true;
        break;
    }
}

答案 2

我在这个xpath中找不到行（tr标签），然后它将如何获得行计数。

String rowsXpath = "//div[@id=\"QosDashpardPanelBottom\"]//div[@id=\"CollectorQoSPerformanceMetricsgrid\"]//div[contains(@class, \"x-grid3-row  x-unselectable-single\")]";

您需要构造如下所示的 xpath 才能在特定表中获取行计数

int rowCount=driver.findElements(By.xpath("//table[@class='x-grid3-row-table']/tbody/tr"))

或者，如果要查找该表中具有特定名称的所有列

构造 xpath，如下所示

int columnCount=driver.findElements(By.xpath("//table[@class='x-grid3-row-table']/tbody//tr//td[@name='RequiredName']"))
