Auto-Trim XML Content when Loading

See more XML Examples

This example explains the "autoTrim" argument that is passed to a method such as LoadXml2. Objective-C

#import <CkoXml.h>

BOOL success = NO;

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

//  If autoTrim is true, then the content inside an leaf element is trimmed.
//  For example:
BOOL autoTrim = YES;
[xml LoadXml2: @"<abc><xyz>  123   </xyz></abc>" autoTrim: autoTrim];
NSLog(@"%@",[xml GetXml]);

//  Output is:
//  (notice the SPACE chars before and after "xyz" are trimmed)

//  <?xml version="1.0" encoding="utf-8" ?>
//  <abc>
//      <xyz>123</xyz>
//  </abc>

//  If autoTrim is false, then the content inside leaf elements are not trimmed.
autoTrim = NO;
[xml LoadXml2: @"<abc><xyz>  123   </xyz></abc>" autoTrim: autoTrim];
NSLog(@"%@",[xml GetXml]);

//  Output is:

//  <?xml version="1.0" encoding="utf-8" ?>
//  <abc>
//      <xyz>  123   </xyz>
//  </abc>

//  The EmitCompact property controls whether XML is emitted indented (pretty-printed)
//  or compact.  For example:

//  Auto-trim + emit compact:
autoTrim = YES;
[xml LoadXml2: @"<abc><xyz>  123   </xyz></abc>" autoTrim: autoTrim];
xml.EmitCompact = YES;
NSLog(@"%@",[xml GetXml]);

//  Output is:

//  <?xml version="1.0" encoding="utf-8" ?>
//  <abc><xyz>123</xyz></abc>

//  No Auto-trim + emit compact:
autoTrim = NO;
[xml LoadXml2: @"<abc><xyz>  123   </xyz></abc>" autoTrim: autoTrim];
xml.EmitCompact = YES;
NSLog(@"%@",[xml GetXml]);

//  Output is:

//  <?xml version="1.0" encoding="utf-8" ?>
//  <abc><xyz>  123   </xyz></abc>
