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. Chilkat2 PHP

<?php

use Chilkat2\Xml;

$xml = new Xml();

// If autoTrim is true, then the content inside an leaf element is trimmed.
// For example:
$autoTrim = true;
$xml->LoadXml2('<abc><xyz>  123   </xyz></abc>', $autoTrim);
echo $xml->GetXml(), "\n";

// 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 = false;
$xml->LoadXml2('<abc><xyz>  123   </xyz></abc>', $autoTrim);
echo $xml->GetXml(), "\n";

// 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 = true;
$xml->LoadXml2('<abc><xyz>  123   </xyz></abc>', $autoTrim);
$xml->EmitCompact = true;
echo $xml->GetXml(), "\n";

// Output is:

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

// No Auto-trim + emit compact:
$autoTrim = false;
$xml->LoadXml2('<abc><xyz>  123   </xyz></abc>', $autoTrim);
$xml->EmitCompact = true;
echo $xml->GetXml(), "\n";

// Output is:

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