Selenium Webdriver: Read a table completely - selenium

Question

Scenerio:In a webpage there are few tables present. I want to read one of the table completely, but the problem is only 10 rows are displayed, for rest i have to scroll down. Actually originally only 10 row are available, when we scroll rest of the filed are rendered.
To solve this i thought i will simulate key down and keep reading, but the problem is even the xpath is not consistent through out so cannot put in a loop too. Xpath for few different cells are:
html/body/div[2]/form/div[1]/div[2]/div/div[2]/div/div[2]/div/div[2]/div/div[2]/div/span/div[1]/div/div/div/div[2]/div/div[2]/table/tbody/tr[1]/td[1]
html/body/div[2]/form/div[1]/div[2]/div/div[2]/div/div[2]/div/div[2]/div/div[2]/div/span/div[1]/div/div/div/div[2]/div/div[2]/table[2]/tbody/tr[3]/td[1]
html/body/div[1]/form/div[1]/div[2]/div/div[2]/div/div[2]/div/div[2]/div/div[2]/div/span/div[1]/div/div/div/div[2]/div/div[2]/table[1]/tbody/tr[10]/td[1]
In what way can i get data in all the cells ?

Answer 1

try to use this approach:
1) actions builder, advanced user API
MoveMouseAction method in particular - Moving the mouse from its current location to another element.
you can get here more info about actions builder
2) also dont forget to use fluent wait until web element is rendered
public WebElement fluentWait(final By locator){
Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
.withTimeout(30, TimeUnit.SECONDS)
.pollingEvery(5, TimeUnit.SECONDS)
.ignoring(NoSuchElementException.class);
WebElement foo = wait.until(
new Function<WebDriver, WebElement>() {
public WebElement apply(WebDriver driver) {
return driver.findElement(locator);
}
}
);
return foo; } ;
By xpathElem=By.xpath("html/body/div[2]/form/div[1]/div[2]/div/div[2]/div/div[2]/div/div[2]/div/div[2]/div/span/div[1]/div/div/div/div[2]/div/div[2]/table/tbody/tr[1]/td[1]");
//getting data from cells
fluentWait(xpathElem).getText().trim();
hope this somehow helps you ;-)
