Remove key=value from url

I need a java library that will make it easy to edit URLs. URLs are given as Strings and must be returned as strings.

I need things such as removing key=value pairs and leaving the url clean and with ?s and &s properly placed.

Use regular expressions and pattern matching:

For instance:

String original = "http://www.someHost.com/somePage?key1=value1&key2=value2";
Pattern keyValPattern = Pattern.compile("\\p{Alpha}\\w+=[^&]+");
Matcher m = keyValPattern.matcher(original);  
m.find(); // find an occurence of key=value pair
String keyVal = m.group(); // get the value of the found pair
// keyVal will be 'key1=value1'
int start = m.start(); // the start index of 'key1=value1' in the original string
int end = m.end(); //the end index of 'key1=value1' in the original string
m.find();
String keyVal2 = m.group();// keyVal2 will be 'key2=value2'
// ... etc

This is simple utility class which can help. I wouldn't use whole library just for that, better is to see what you needs and create your own utility class with methods which you need.

Use the Java URL class to parse the original string and change the parameters, then just toString() it again for your result.
