Handling Namespaces in XML Tags

See more XML Examples

Demonstrates new features added in Chilkat v9.5.0.77 for helping with namespace prefixed tags. Objective-C

#import <CkoXml.h>

// First create some XML using namespace prefixed tags.

// Create this XML. 
// Use this online tool to generate the code from sample XML: 
// Generate Code to Create XML

// <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
//    xmlns:scm="http://www.springcm.com/atlas/webservices/v201308/scm/">
//    <soapenv:Header/>
//    <soapenv:Body>
//       <scm:AccountGetCurrent>
//          <scm:token>123</scm:token>
//       </scm:AccountGetCurrent>
//    </soapenv:Body>
// </soapenv:Envelope>

// Go to the "Body" tag, regardless of namespace prefix.

    NSLog(@"%@",@"Body child not found.");
    return;

// Get the full tag w/ namespace prefix:
// Output is "soapenv:Body"
NSLog(@"%@",xmlBody.Tag);

// Get the namespace prefix:
// Output is "soapenv"

// Check to see if the namespace prefix equals "soapenv";

// Change just the namespace prefix of the tag
