Simple RegEx Help

[VUNETdotUS]

How can I get the text after matching string is found:

var str = "1111>AAAA<2222>BBBB<3333>CCCC";

if(str.indexOf("2222>")){

//how to get "BBBB" value following my "2222>" but before "<3333"
or any < sign?

}

Please, recommend a RegEx if possible. Thanks.

var re = new RegExp('('+search+'>)([^<$]*)','');

var result = stri.match(re);

result = (result)?result[2]:'Not found';

alert(result);

I wonder why if I make global search like var re = new
RegExp('('+search+'>)([^<$]*)','g'); then result[2] cannot be used but
result can?

Read the specs of match() on the global flag.

Programming is not a trial and error art,
but is understanding the functionality.

| 15.5.4.10 String.prototype.match (regexp)
|
| If `regexp' is not an object whose [[Class]] property is "RegExp", it is
| replaced with the result of the expression new RegExp(regexp). Let
| `string' denote the result of converting the this value to a string.
| Then do one of the following:
|
| • If regexp.global is `false': Return the result obtained by invoking
| RegExp.prototype.exec (see section 15.10.6.2) on `regexp' with `string'
| as parameter.
|
| • If regexp.global is `true': Set the regexp.lastIndex property to 0 and
| invoke RegExp.prototype.exec repeatedly until there is no match.
| If there is a match with an empty string (in other words, if the value
| of regexp.lastIndex is left unchanged), increment regexp.lastIndex by 1.
| Let n be the number of matches. The value returned is an array with
| the length property set to n and properties 0 through n–1 corresponding
| to the first elements of the results of all matching invocations of
| RegExp.prototype.exec.
