Java 用两个（或更多）表达式替换字符串

Question

我想替换这个字符串： - http://fitness.com/gorilla-bumpers - http://www.fitness.com/gorilla-bumpers 表达式 "Product: gorilla-bumpers".

我有以下代码：

final String url = eElement.getElementsByTagName("url").item(0).getTextContent();
final String qty = eElement.getElementsByTagName("quantity").item(0).getTextContent();
//I 've got "url" and "qty" values from Xml after parsing it

String product = url.replace("http://fitness.com/", "Product: ");           
System.out.println(product + " was added to the cart with Qty = " + qty);

如何在 Java 中添加一个替换项？将感谢提供的几种变体。谢谢

Answer 1

就这样吧：

String product = url.replace( "http://fitness.com/", "Product: " ).replace( "http://www.fitness.com/", "Product: " );

您也可以尝试正则表达式，因为 .replaceAll 函数采用正则表达式

String product = url.replaceAll( "http:.*\/", "Product: " );

请注意，我不是正则表达式方面的专家，您应该创建自己的正则表达式。这个替换每个 http://BLABLA/ 个字符串

Answer 2

执行以下操作：

final String url = eElement.getElementsByTagName("url").item(0).getTextContent();
final String qty = eElement.getElementsByTagName("quantity").item(0).getTextContent();

String product = url.replace("http://fitness.com/", "Product: ")
                .replace("http://www.fitness.com/", "Product: ");
        System.out.println(product + " was added to the cart with Qty = " + qty);

Answer 3

试试这个-

final String url = eElement.getElementsByTagName("url").item(0).getTextContent();
final String qty = eElement.getElementsByTagName("quantity").item(0).getTextContent();

String product = url.replaceAll("http://fitness.com/", "Product: ").replaceAll("http://www.fitness.com/", "Product: ");

System.out.println(product + " was added to the cart with Qty = " + qty);
