Find Direct Child with Specific Tag

See more XML Examples

Demonstrates how to find a direct child having a specific tag.

The input XML, available at http://www.chilkatsoft.com/data/fruit.xml, is this:

<root>
    <fruit color="red">apple</fruit>
    <fruit color="green">pear</fruit>
    <veg color="orange">carrot</veg>
    <meat animal="cow">beef</meat>
    <xyz>
        <fruit color="blue">blueberry</fruit>
        <veg color="green">broccoli</veg>
    </xyz>
    <fruit color="purple">grape</fruit>
    <cheese color="yellow">cheddar</cheese>
</root>

Objective-C

#import <CkoXml.h>

BOOL success = NO;

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

// The sample input XML is available at http://www.chilkatsoft.com/data/fruit.xml
success = [xml LoadXmlFile: @"qa_data/xml/fruit.xml"];
if (success != YES) {
    NSLog(@"%@",xml.LastErrorText);
    return;
}

// Find the direct child node having the tag "meat", and 
// return a new instance of the XML object referencing the
// child node, if found.
CkoXml *child = [xml FindChild: @"meat"];
if (xml.LastMethodSuccess == NO) {
    NSLog(@"%@",@"No direct child having the tag \"meat\" was found.");
}
else {
    NSLog(@"%@%@",@"Content = ",child.Content);

}

// The same can be accomplished without creating a new 
// XML object instance.  Instead, the FindChild2 method updates
// the caller's internal reference to the found child, if successful.
success = [xml FindChild2: @"meat"];
if (success == YES) {
    // Success!  The xml object now references the found child.
    NSLog(@"%@%@",@"Content = ",xml.Content);
    // Restore the reference back to the parent.
    success = [xml GetParent2];
}
else {
    NSLog(@"%@",@"No direct child having the tag \"meat\" was found.");
