(PHP ActiveX) Auto-Trim XML Content when Loading

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

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Xml')
$xml = new COM("Chilkat.Xml");

// If autoTrim is 1, then the content inside an leaf element is trimmed.
// For example:
$autoTrim = 1;
$xml->LoadXml2('<abc><xyz>  123   </xyz></abc>',$autoTrim);
print $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 0, then the content inside leaf elements are not trimmed.
$autoTrim = 0;
$xml->LoadXml2('<abc><xyz>  123   </xyz></abc>',$autoTrim);
print $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 = 1;
$xml->LoadXml2('<abc><xyz>  123   </xyz></abc>',$autoTrim);
$xml->EmitCompact = 1;
print $xml->getXml() . "\n";

// Output is:

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

// No Auto-trim + emit compact:
$autoTrim = 0;
$xml->LoadXml2('<abc><xyz>  123   </xyz></abc>',$autoTrim);
$xml->EmitCompact = 1;
print $xml->getXml() . "\n";

// Output is:

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