Question

我想替换这个字符串： - http://fitness.com/gorilla-bumpers - http://www.fitness.com/gorilla-bumpers，表达式为＆＃34;产品：gorilla-bumpers＆＃34;。

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中再添加一个替代品？将提供几种变体。谢谢

Answer 1

就像这样：

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

此外，您可以尝试正则表达式，因为.replaceAll函数需要正则表达式

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

请注意，我不是正则表达式的专家，你应该创建自己的。这个替换每个http://BLABLA/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);

Java用两个（或更多）表达式
