// var sURLPath = sURLPathChars + '*' + sEndChars;
var sURLPath = '[0-9a-z\\.\\-\\_\\/\\~\\%\\+\\?\\=\\&\\#\\*\\:\\;\\,]+[0-9a-z\\-\\_\\/\\~\\%\\+\\?\\=\\&\\#\\*\\:\\;\\,]';

// var sRegExpEmail = '(' + sUserNamePasswordChars + '+@' + '(?:(?:(?:' + sAllSubDomain + '\\.)+' + sTopLevelDomains + ')|(?:' + sIPAddress + '))(?:' + sGetStringChars + '+' + sEndChars + ')?)';
var sRegExpEmail = '([0-9a-z\\.\\-\\_\\+]+@[0-9a-z\\.\\-]+[a-z])';
