String parsing in java

If I have a long string, say:

"blah blah blah blah blah .............. <ns:return>72.5</ns:return>......abcdejijalskjd;a;l&*^@#()&...."

and I want to extract the value in between the tag, how can I do that?

Use Commons Lang StringUtils

String between = substringBetween(longString, "<ns:return>", "</ns:return>");

Do something like:

String str = "blah .... <ns:return>72.5</ns:return>";
String searchBegin = "<ns:return>";
String searchEnd = "</ns:return>";
String subStr = str.substring(str.indexOf(searchBegin) + searchBegin.length(), str.indexOf(searchEnd));

If everything is always going to be the same, you could use a regex...

(?<=<ns:return>)([0-9.]+)(?=</ns:return>)

You can use regular expressions, something like:

Pattern p = Pattern.compile(".*<ns:return>(.*)</ns:return>.*");
Matcher m = p.matcher(yourString);

float yourValue = Float.parseFloat(m.group(1));

If it's an xml then use xml parser. Otherwise, you can use regular expression.
