清单 <WebElement> 仅适用于表格的前3列

Question

Where it says findElements(By.xpath("td[]")) , how to get only the td[1] , td[2] , td[3] elements in the List ?

WebElement Webtable = driver.findElement(By.xpath(""));
List<WebElement> TotalRowCount = Webtable.findElements(By.xpath(""));
int RowIndex = 1;
for (WebElement rowElement : TotalRowCount) {
    List<WebElement> TotalColumnCount = rowElement.findElements(By.xpath("td[]"));
    int ColumnIndex = 1;
    for (WebElement colElement : TotalColumnCount) {
        ColumnIndex = ColumnIndex +1;
    }
    RowIndex = RowIndex + 1;
}

Answer 1

Just add those items to your list.

WebElement Webtable = driver.findElement(By.xpath(""));
int num_elements_to_get = 3;
int rows = Webtable.findElements(By.xpath("tr")).size();
List<WebElement> data = new ArrayList<WebElement>();
for(int i = 1; i <= rows; i++) {
    for(int j = 1; j <= num_elements_to_get; j++) {
        data.add(Webtable.findElement(By.xpath("tr["+i+"]/td["+j+"]")));
    }
}

Then the column elements that you want will be stored in data.

您应该尝试使用xpath position()函数，如下所示，该函数将仅为每行选择前三列：

List<WebElement> TotalColumnCount = rowElement.findElements(By.xpath("td[position() <= 3]"));
