Selenium WebDriver: Help getting specific row data from a table
提问by Doctor Who
I have a table with 12 columns, one of the columns is named "quantity" what I need to do is find out which column is the quantitiy one and then get all of the data from the table for that column.
我有一个包含 12 列的表，其中一列名为“数量”，我需要做的是找出哪一列是数量一列，然后从表中获取该列的所有数据。
This is some rough code that I have written but at the moment it is just giving me all the data from the table instead of the part that I need.
这是我写的一些粗略的代码，但目前它只是给我表中的所有数据，而不是我需要的部分。
// Get the table name
WebElement table = driver.findElement(By.className("compact"));
// Get all the Table headers and look for one the element called quantity.
List<WebElement> allHeaders = table.findElements(By.tagName("th"));
System.out.println("This is the total numbers of headers" + allHeaders.size());
int quantityHead = 0;
// Get the column where the quantity is listed
for(WebElement header : allHeaders)
{
quantityHead++;
if(header.getText().equalsIgnoreCase("Quantity"))
{
System.out.println(header.getText());
System.out.println(quantityHead + " is the column number for the quantity");
}
}
// Now get all the TR elements from the table
List<WebElement> allRows = table.findElements(By.tagName("tr"));
System.out.println("This is how many allRows: " + allRows.size());
// This is how many items are in the order item table. number of rows - 1 coz top row is the headings
int z = allRows.size() - 1;
System.out.println("This is how many items are in the table : " + z );
// Work out the cells we need to get by
// iterate over all the td
for (WebElement row : allRows) {
// now we have all the td
List<WebElement> cells = row.findElements(By.tagName("td"));
for (WebElement cell : cells) {
for(int x=0; x <= allHeaders.size(); x++)
{
int y = x;
// if y = the value where the qty header is then output the text of that cell
if(y == quantityHead )
{
System.out.println();
System.out.println("The quanity is: " + cell.getText());
}
}
}
}

First identify the column position of the quantity in the table. then just find the element by the xpath
首先确定表中数量的列位置。然后只需通过 xpath 找到元素
WebElement table = driver.findElement(By.className("compact"));
List<WebElement> th=table.findElements(By.tagName("th"));
int col_position=0;
for(int i=0;i<th.size();i++){
if("quantity".equalsIgnoreCase(th.get(i).getText())){
col_position=i+1;
break;
}
}
List<WebElement> FirstColumns = table.findElements(By.xpath("//tr/td["+col_position+"]"));
for(WebElement e: FirstColumns){
System.out.println(e.getText());
}
Hope this helps
希望这可以帮助
