Verifying HTML table data in WebDriver

Keeping in mind your excerpt from the question:

I need to verify the values xyz, abcd, 1234, 5678 on the webpage

I suggest you try to identify these values using locators and then asserting/verifying the same.

In this example I have used XPath ( a bit verbose for clarity)as the locating strategy.Hope this helps.

    try {
    assertEquals("xyz", driver.findElement(By.xpath("//table//tr[1]/td[1]")).getText());
    } catch (Error e) {
    verificationErrors.append(e.toString());
}
try {
    assertEquals("abcd", driver.findElement(By.xpath("//table//tr[1]/td[2]")).getText());
    } catch (Error e) {
    verificationErrors.append(e.toString());
}
try {
    assertEquals("1234", driver.findElement(By.xpath("//table//tr[2]/td[1]")).getText());
    } catch (Error e) {
    verificationErrors.append(e.toString());
}
try {
    assertEquals("5678", driver.findElement(By.xpath("//table//tr[2]/td[2]")).getText());
    } catch (Error e) {
    verificationErrors.append(e.toString());
}

Your approach will depend on whether that table will only ever contain 2 rows and 2 columns. Will the rows and columns always exist in the same order? If not then the xcode example provider before will work, if not you might need to be a bit more creative.

One approach that I've used before to crawl through a table is similar to this.

Define a WebElement that represents your table.

WebElement yourTable = driver.findElement(By.tagname("table"));

Next create a List of WebElements that represent each row in the table.

List<WebElement> tableRows = yourTable.findElements(By.tagname("tr");

Finally, you can loop through the rows of the table until you find the data you are looking for.

for(int i=0; i<tableRows.size(); i++){
    WebElement row  = tableRows.get(i);
    now do whatever you want with your WebElement that represents a single row of the table;
    }

Hope this helps.
