# The Chilkat XML parser is freeware.
	
# Simple Perl XML example to iterate over child nodes deleting each while
# in progress.
$xml = new chilkat::CkXml();

# Create this XML:
# <?xml version="1.0" encoding="utf-8" ?>
# <colors>
#         <color>red</color>
#         <color>blue</color>
#         <color>green</color>
#         <color>yellow</color>
#         <color>purple</color>
#         <color>orange</color>
# </colors>

# First create the XML:
$xml->put_Tag("colors");
$xml->NewChild2("color","red");
$xml->NewChild2("color","blue");
$xml->NewChild2("color","green");
$xml->NewChild2("color","yellow");
$xml->NewChild2("color","purple");
$xml->NewChild2("color","orange");
$xml->SaveXml("output/colors.xml");

# Load the XML and iterate/delete:
$xml2 = new chilkat::CkXml();
$xml2->LoadXmlFile("output/colors.xml");

while ($xml2->get_NumChildren() > 0)
{
	$child = $xml2->GetChild(0);
	print $child->content . "\n";
	$child->RemoveFromTree();
