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.

Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // 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:

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

  final xml = CkXml();
  xml.loadXml(s);

  print(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');
  print(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>
