// Generate this XML with the code that follows:

// 	<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
// 	 <soap:Header>	     
// 	  <wsse:Security xmlns:wsse="http://schemas.xmlsoap.org/ws/2003/06/secext">
// 	   <wsse:UsernameToken wsu:Id="sample" 
// 	       xmlns:wsu="http://schemas.xmlsoap.org/ws/2003/06/utility">
// 	    <wsse:Username>sample</wsse:Username>
// 	    <wsse:Password Type="wsse:PasswordText">oracle</wsse:Password>
// 	    <wsu:Created>2004-05-19T08:44:51Z</wsu:Created>
// 	   </wsse:UsernameToken>
// 	  </wsse:Security>
// 	  <wsse:Security soap:actor="oracle" 
// 	      xmlns:wsse="http://schemas.xmlsoap.org/ws/2003/06/secext">

// 	       xmlns:wsu="http://schemas.xmlsoap.org/ws/2003/06/utility">
// 	    <wsse:Username>myUsername</wsse:Username>
// 	    <wsse:Password Type="wsse:PasswordText">myPassword</wsse:Password>
// 	    <wsu:Created>2004-05-19T08:46:04Z</wsu:Created>

// 	  <soap:Body>
// 	   <getHello xmlns="http://www.oracle.com"/>
// 	  </soap:Body>
// 	</soap:Envelope>
// 

// First build the outer housing:
CkoXml *xml = [[CkoXml alloc] init];
xml.Tag = @"soap:Envelope";
[xml AddAttribute: @"xmlns:soap" value: @"http://schemas.xmlsoap.org/soap/envelope/"];
[xml UpdateChildContent: @"soap:Header" value: @""];
[xml UpdateAttrAt: @"soap:Body|getHello" autoCreate: YES attrName: @"xmlns" attrValue: @"http://www.oracle.com"];

// Get the current date/time in a string with this format: 2004-05-19T08:46:04Z
CkoDateTime *dt = [[CkoDateTime alloc] init];
[dt SetFromCurrentSystemTime];
BOOL bLocal = NO;
NSString *created = [dt GetAsTimestamp: bLocal];

// Now build each UsernameToken block:
CkoXml *wsse1 = [[CkoXml alloc] init];
wsse1.Tag = @"wsse:Security";
[wsse1 AddAttribute: @"xmlns:wsse" value: @"http://schemas.xmlsoap.org/ws/2003/06/secext"];
[wsse1 UpdateAttrAt: @"wsse:UsernameToken" autoCreate: YES attrName: @"wsu:Id" attrValue: @"sample"];
[wsse1 UpdateAttrAt: @"wsse:UsernameToken" autoCreate: YES attrName: @"xmlns:wsu" attrValue: @"http://schemas.xmlsoap.org/ws/2003/06/utility"];
[wsse1 UpdateChildContent: @"wsse:UsernameToken|wsse:Username" value: @"sample"];
[wsse1 UpdateAttrAt: @"wsse:UsernameToken|wsse:Password" autoCreate: YES attrName: @"Type" attrValue: @"wsse:PasswordText"];
[wsse1 UpdateChildContent: @"wsse:UsernameToken|wsse:Password" value: @"oracle"];
[wsse1 UpdateChildContent: @"wsse:UsernameToken|wsu:Created" value: created];

CkoXml *wsse2 = [[CkoXml alloc] init];
wsse2.Tag = @"wsse:Security";
[wsse2 AddAttribute: @"soap:actor" value: @"oracle"];
[wsse2 AddAttribute: @"xmlns:wsse" value: @"http://schemas.xmlsoap.org/ws/2003/06/secext"];
[wsse2 UpdateAttrAt: @"wsse:UsernameToken" autoCreate: YES attrName: @"wsu:Id" attrValue: @"oracle"];
[wsse2 UpdateAttrAt: @"wsse:UsernameToken" autoCreate: YES attrName: @"xmlns:wsu" attrValue: @"http://schemas.xmlsoap.org/ws/2003/06/utility"];
[wsse2 UpdateChildContent: @"wsse:UsernameToken|wsse:Username" value: @"oracle"];
[wsse2 UpdateAttrAt: @"wsse:UsernameToken|wsse:Password" autoCreate: YES attrName: @"Type" attrValue: @"wsse:PasswordText"];
[wsse2 UpdateChildContent: @"wsse:UsernameToken|wsse:Password" value: @"oracle"];
[wsse2 UpdateChildContent: @"wsse:UsernameToken|wsu:Created" value: created];

// Insert the UsernameToken blocks:
CkoXml *xHeader = [xml GetChildWithTag: @"soap:Header"];
[xHeader AddChildTree: wsse1];
[xHeader AddChildTree: wsse2];

// Show the XML:
NSLog(@"%@",[xml GetXml]);
