Demonstrates the XML UpdateAttrAt method to update attribute name/value pairs in XML.

Note: This example requires Chilkat v9.5.0.64 or later.

Objective-C

#import <CkoXml.h>

//  Note: This example requires Chilkat v9.5.0.64 or later.
CkoXml *xml = [[CkoXml alloc] init];

xml.Tag = @"animals";

BOOL autoCreate = YES;

//  When the autoCreate argument equals true, the UpdateAttrAt
//  method auto-creates the children as needed:
[xml UpdateAttrAt: @"penguin" autoCreate: autoCreate attrName: @"feature" attrValue: @"flightless bird"];
[xml UpdateAttrAt: @"mammal|rodent|squirrel" autoCreate: autoCreate attrName: @"feature" attrValue: @"bushy tail"];
[xml UpdateAttrAt: @"mammal|rodent|rat" autoCreate: autoCreate attrName: @"feature" attrValue: @"long hairless tail"];

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

//  	<?xml version="1.0" encoding="utf-8" ?>
//  	<animals>
//  	    <penguin feature="flightless bird" />
//  	    <mammal>
//  	        <rodent>
//  	            <squirrel feature="bushy tail" />
//  	            <rat feature="long hairless tail" />
//  	        </rodent>
//  	    </mammal>
//  	</animals>
//  

//  Now update each node's "feature" attribute..
[xml UpdateAttrAt: @"penguin" autoCreate: autoCreate attrName: @"feature" attrValue: @"black and white"];
[xml UpdateAttrAt: @"mammal|rodent|squirrel" autoCreate: autoCreate attrName: @"feature" attrValue: @"grey, red, or black"];
[xml UpdateAttrAt: @"mammal|rodent|rat" autoCreate: autoCreate attrName: @"feature" attrValue: @"brown, grey, white, or black"];

NSLog(@"%@",[xml GetXml]);

//  	<?xml version="1.0" encoding="utf-8" ?>
//  	<animals>
//  	    <penguin feature="black and white" />
//  	    <mammal>
//  	        <rodent>
//  	            <squirrel feature="grey, red, or black" />
