Question

我正在尝试在两个字符串之间获取数据＆＃34;帐户：＆＃34;和＆＃34;帐户＆＃34;使用正则表达式从下面的字符串。

List<WebElement> rstar = dr.findElements(By.xpath("//*[@id='cm_cr-review_list']//div[@class='a-row']//a[@class='a-link-normal']//i"));
                String c;
                    for(WebElement erstar : rstar) {
                        c=erstar.getAttribute("innerText");

                        System.out.println(c);

我使用的正则表达式是：

    String str= "Order Confirmation Account: Sample Account ID: 1111"

我得到的实际输出是：

    Pattern pattern = Pattern.compile("Account:(.*)Account");
    Matcher matcher = pattern.matcher(str);
    System.out.println("Account name is:"+matcher.group(1));

预期输出为：

java.lang.IllegalStateException: No match found
at java.util.regex.Matcher.group(Unknown Source)

at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source)

我的正则表达式出了什么问题？

Answer 1

模式需要匹配整个String，所以

".*Account:(.*)Account.*"

正则表达式在java中的两个字符串之间获取数据
