java - Selenium : XPATH invalid when stocking it in a String

Question

我想使用一个函数在屏幕上显示下拉列表的当前值，因为 Selenium 代码不太漂亮。

以下内容在我的主脚本中完美运行:

new Select(driver.findElement(By.id("secId:mainBody:vboxlist:s_m9_aa2::content"))).selectByVisibleText(contract.getCreditype());

但是使用该函数，它不起作用:

writeScreen("Description : ", "secId:mainBody:vboxlist:s_m9_aa2::content");

public void writeScreen(String description, String identifiant) {
            String xpath="//*[@id=\\\""+identifiant+"\\\"]";
            Select select = new Select(driver.findElement(By.xpath(xpath)));
            WebElement option = select.getFirstSelectedOption();
            String defaultItem = option.getText();
            System.out.println(description+defaultItem);

我收到以下错误:

org.openqa.selenium.InvalidSelectorException: invalid selector: Unable to locate an element with the xpath expression //[@id=\"secId:mainBody:vboxlist:s_m9_aa2::content\"] because of the following error: SyntaxError: Failed to execute 'evaluate' on 'Document': The string '//[@id=\"secId:mainBody:vboxlist:s_m9_aa2::content\"]' is not a valid XPath expression.

当我检查 XPATH 时，它与我的第一个工作示例中的完全相同。

您的xpath错误，请更改String xpath="//*[@id=\\\""+identifiant+"\\\"]";如下:

String xpath="//*[@id='"+identifiant+"']";
