This "hasChildNodes()" exercise is simple enough to make it clear and understandable. Or,
you could take it as a tag empty check. By Richard Holm, Sweden.
<?php
$xmldoc=
'<?xml version="1.0" ?>
<root>
<text>Text</text>
<none/>
<empty></empty>
<space> </space>
</root>';
$domdoc=new DOMDocument();
$domdoc->loadXML($xmldoc);
$tag=$domdoc->getElementsByTagName('root')->item(0);
$v=$tag->hasChildNodes()?" hasChildNodes":" hasNoChildNodes";
echo $tag->tagName.$v."<br/>";
$tag=$domdoc->getElementsByTagName('text')->item(0);
$v=$tag->hasChildNodes()?" hasChildNodes":" hasNoChildNodes";
echo $tag->tagName.$v."<br/>";
$tag=$domdoc->getElementsByTagName('none')->item(0);
$v=$tag->hasChildNodes()?" hasChildNodes":" hasNoChildNodes";
echo $tag->tagName.$v."<br/>";
$tag=$domdoc->getElementsByTagName('empty')->item(0);
$v=$tag->hasChildNodes()?" hasChildNodes":" hasNoChildNodes";
echo $tag->tagName.$v."<br/>";
$tag=$domdoc->getElementsByTagName('space')->item(0);
$v=$tag->hasChildNodes()?" hasChildNodes":" hasNoChildNodes";
echo $tag->tagName.$v."<br/>";
?>
Output:
root hasChildNodes
text hasChildNodes
none hasNoChildNodes
empty hasNoChildNodes
space hasChildNodes
