Demonstrates and explains the TagPath property.

Note: The TagPath property was introduced in Chilkat v9.5.0.77

Objective-C

#import <CkoXml.h>
#import <NSString.h>

BOOL success = NO;

CkoXml *xml = [[CkoXml alloc] init];

// Load some XML:
success = [xml LoadXml: @"<a><bbb><ccc><ddd>1</ddd><ddd><z>zzz</z></ddd><ddd>3</ddd></ccc></bbb></a>"];

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

// This is what we have:

// <?xml version="1.0" encoding="utf-8"?>
// <a>
//     <bbb>
//         <ccc>
//             <ddd>1</ddd>
//             <ddd>
//                 <z>zzz</z>
//             </ddd>
//             <ddd>3</ddd>
//         </ccc>
//     </bbb>
// </a>

// The TagPath property is read-only property that returns the unique path to the
// node from the document root.

// For example:
BOOL found = [xml SearchForTag2: xml tag: @"z"];
if (found == YES) {
    // We found a node having the tag "z".
    // The TagPath property tells us the location in the document.
    NSString *tagPath = xml.TagPath;
    NSLog(@"%@",tagPath);

    // The tagPath is bbb|ccc|ddd[1]|z

    // If we to back to the document root, we can get to the given node via the tagPath.
    [xml GetRoot2];
    NSLog(@"%@",xml.Tag);
    // The root tag is "a".

    // Follow the tagPath to the "z" node:
    found = [xml FindChild2: tagPath];
    NSLog(@"%@%d%@%@",@"found = ",found,@", tag = ",xml.Tag);
    // We are now at "z".
