You don't need a regular expression for this; firing up the regex engine is completely overkill for such a simple task.

Just use basic string manipulation:

function getSubStr(str, delim) {
    var a = str.indexOf(delim);

    if (a == -1)
       return '';

    var b = str.indexOf(delim, a+1);

    if (b == -1)
       return '';

    return str.substr(a+1, b-a-1);
    //                 ^    ^- length = gap between delimiters
    //                 |- start = just after the first delimiter
}

print(getSubStr('|text to get| Other text.... migh have "|"s ...', '|'));

// Output: text to get
