(Objective-C) XML Accumulate Tag Content

Demonstrates how to use the AccumulateTagContent method of the XML class.

Imagine the XML document for this test contains the following:

<?xml version="1.0" encoding="utf-8"?>
<abc>
	<zzz>The quick brown fox</zzz>
	<xyz>
	    <zzz>hello world!</zzz>
	</xyz>
	<mmm>
	    <zzz>jumped over the lazy dog.</zzz>
	</mmm>
</abc>

#import <CkoXml.h>

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

BOOL success = [xml LoadXmlFile: @"my_document.xml"];
if (success != YES) {
    NSLog(@"%@",xml.LastErrorText);
    return;
}

// Accumulate the textual content within the "zzz" nodes of this
// XML.  Skip sub-trees rooted at nodes having the tag "xyz".
// For the given test XML, the resulting accumulated text should be:
// "The quick brown fox jumped over the lazy dog."
NSLog(@"%@",[xml AccumulateTagContent: @"zzz" skipTags: @"xyz"]);
