收集 WebElements 列表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;
}

列表行包含具有多列的单个行，我试图在列中找到包含特定名称的行。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 以及单个 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。

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\")]";

这是HTML：

是的，这绝对是可能的。看到这个：

// 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，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，实际上只需要少量 :)。）

既然我抓住了你所追求的东西，我认为你根本不需要这种方法。试试这个：

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 + "'] ]

这只会为您找到使用单个命令所需的单行。

如果您想坚持当前的解决方案，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;
    }
}

我在这个 xpath 中没有找到行（tr 标签），那么它将如何获得行数。

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

您需要构建类似下面的 xpath 以获取特定表中的行数

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

或者，如果您想查找该表中具有特定名称的所有列

像下面这样构造xpath

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