PHP将XML rootNode内容作为String获取

Question

How can i get the content of an XML as string? I have a xml like this:

<?xml version="1.0" encoding="utf-8"?>
<section>
  <paragraph>some content</paragraph>
  <custom>some more content</custom>
</section>

and i want the content of section as a string like this:

  <paragraph>some content</paragraph>
  <custom>some more content</custom>

every doc i read so far only explains how to get the content of a subnode but not of the root node.

Answer 1

It can be achieved using DOMDocument (Press here to See it in action)

$xmlStr = '<?xml version="1.0" encoding="utf-8"?>
<section>
  <paragraph>some content</paragraph>
  <custom>some more content</custom>
</section>
';

$xml = new DOMDocument(); 
$xml->loadXML($xmlStr);
if($xml->childNodes->length > 0) {
  foreach($xml->childNodes->item(0)->childNodes as $rootChildNode){
      echo $xml->saveXML($rootChildNode); 
    }
}
