使用带有xpath的嵌套FindElement解析表（在JAVA中）

Question

I'm a bit new to selenium and xpath and am curious if I'm doing something right and how findElement will behave. I've looked and looked for an example but I can't find one.

Given this Table (simplified but relevant)

  <table> <thead></thead> <tbody> <tr> <td>R1C1</td> <td>R1C2</td> </tr> <tr> <td>R2C1</td> <td>R2C2</td> </tr> </tbody> </table> 

If I use the following, will I have the info I'm expecting?

WebElement r1 = driver.findElement(By.xpath("//table/tbody/tr[1]"));
String r1c1 = r1.findElement(By.xpath("//td[1]")).getText();
String r1c2 = r1.findElement(By.xpath("//td[2]")).getText();

WebElement r2 = driver.findElement(By.xpath("//table/tbody/tr[2]"));
String r2c1 = r1.findElement(By.xpath("//td[1]")).getText();
String r2c2 = r1.findElement(By.xpath("//td[2]")).getText();

Alt:

String r2c1 = driver.findElement(By.xpath("//table/tbody/tr[2]")).findElement(By.xpath("//td[1]")).getText();

Please keep in mind this is HIGHLY simplified in comparison to what I'm actually doing, but I'm confident the rest will work. My question revolves specifically around finding an element off of another element. And, no, there are no unique Class/ID tags I can utilize to specifically identify a given cell of the table.

Will this work as I expect it to? (I realize I could just try it, but then the answer wouldn't be available online for the next person to search for)

Answer 1

I would rather suggest to Keep It Short and Simple for a better Execution Performance .

If you want to getText() from the following four WebElements keep it as simple as :

String r1c1 = driver.findElement(By.xpath("//table//tbody/tr/td")).getAttribute("innerHTML");
String r1c2 = driver.findElement(By.xpath("//table//tbody/tr//following::td[2]")).getAttribute("innerHTML");

String r2c1 = driver.findElement(By.xpath("//table//tbody//following::tr[2]/td")).getAttribute("innerHTML");
String r2c2 = driver.findElement(By.xpath("//table//tbody//following::tr[2]//following::td[2]")).getAttribute("innerHTML");
