java无法从html站点代码导入数字
所以我想用下面的代码从网站上获取号码。我想要的是输入号码“Pieniądze”（21762）并替换“”和“PLN”，所以它将是号码，但我下面发布的代码不起作用。有什么建议吗，解析的错误在哪里
int money;
money=Integer.parseInt((driver.findElement(By.xpath("/html/body/div[1]/div/div[5]/div[4]/table/tbody/tr/td[2]/text()[1]"))).getText().replace(" ", "").replace("PLN", ""));

你的
xpath返回String，而不是WebElement。从xpath中删除/text()[1]或从结果中删除getText()方法
