如何使用 xpath 识别第 n 个子元素?
我们可以通过 xpath 使用以下方式来识别第 n 个子元素 -
通过添加带有索引的方括号。
通过在 xpath 中使用 position () 方法。
示例
import org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; public class SubElement { public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ChromeDriver(); String url = "https://tutorialspoint.com/index.htm"; driver.get(url); driver.manage().window().maximize(); driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); // xpath using position() targeting the first element with type text driver.findElement(By.xpath("//input[@type='text'][position()=1]")) .click(); driver.close(); } }
示例
import org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; public class RowCount { public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ChromeDriver(); String url = "https://tutorialspoint.com/plsql/plsql_basic_syntax.htm"; driver.get(url); driver.manage().window().maximize(); driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); // xpath with index appended to get the data from the row 2 of table List<WebElement> rows = driver.findElements(By.xpath("//table/tbody/tr[2]/td")); System.out.println(“The number of data in row 2 is “+ rows.size()); driver.close(); } }
