Scrub Xml

See more XML Examples

Demonstrates the Scrub method for some common XML cleaning needs.

Note: This example requires Chilkat v9.5.0.77 or greater.

Objective-C

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

BOOL success = NO;

//  The Scrub method has options for trimming whitespace from the ends of attributes and content,
//  trimming inside whitespace, and for case conversion for tags and attribute names.

//  Trimming inside whitespace is defined as replacing CR, LF, and tab chars with SPACE chars, and 
//  removing extra SPACE chars so that at most one SPACE separates non-SPACE chars.

//  For example, load the following XML:

NSString *s = @"<xyz><td class=\" colHoldingPercent col7\" style=\"border-bottom-color: rgb(221, 221, 221);               border-image-outset: 0;  \"> abc\r\n123    456</td></xyz>";

CkoXml *xml = [[CkoXml alloc] init];
success = [xml LoadXml: s];

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

//  The XML before scrubbing is:

//  <xyz>
//      <td class=" colHoldingPercent col7" style="border-bottom-color: rgb(221, 221, 221);               border-image-outset: 0;  ">abc
//  123    456</td>
//  </xyz>

[xml Scrub: @"AttrTrimEnds,AttrTrimInside,ContentTrimEnds,ContentTrimInside"];
NSLog(@"%@",[xml GetXml]);

//  The XML after scrubbing is:

//  <?xml version="1.0" encoding="utf-8"?>
//  <xyz>
//      <td class="colHoldingPercent col7" style="border-bottom-color: rgb(221, 221, 221); border-image-outset: 0;">abc 123 456</td>
//  </xyz>
