Trying to access XML data using SimpleXMLElement

[Morpheous]

Hello,

I have been working with PHP for many years, but have avoided XML parsing - now I know why. I am having some difficultly. In the following XML example, I am trying to read domain:name and domain:reason. I have struggled for the past 3 nights.

 

<?xml version="1.0" encoding="utf-8"?> 
<epp xmlns="urn:ietf:params:xml:ns:epp-1.0">
<response>
	<result code="1000">
		<msg>Command completed successfully</msg>
	</result>
	<resData>
		<domain:chkData xmlns:domain="urn:ietf:params:xml:ns:domain-1.0">
		<domain:cd>
			<domain:name avail="0">foo.com</domain:name>
			<domain:reason>registered</domain:reason>
		</domain:cd>
		<domain:cd>
			<domain:name avail="0">foo.net</domain:name>
			<domain:reason>registered</domain:reason>
		</domain:cd>
		<domain:cd>
			<domain:name avail="0">foo.org</domain:name>
			<domain:reason>registered</domain:reason>
		</domain:cd>
		</domain:chkData>
	</resData>
	<trID>
		<svTRID>test-0000-0000</svTRID>
	</trID>
</response>
</epp> 

 

The code I am using is below. This assumes the above XML data is in a variable called $xmldata

 

$xml = new SimpleXMLElement($xmldata);
foreach ($xml->response->resData as $entry){
  $namespaces = $entry->getNameSpaces(true);
  $domain = $entry->children($namespaces['domain']); 
  echo "Domain : " . $domain->name. "<br />";
  echo "Domain : " . $domain->reason . "<br />";
}

 

Can anyone advise where I am going wrong?

 

Thanks in advance.

Interestingly, I have managed to solve it.

Here is the code.

 

foreach ($xml->response->resData as $entry){
//Use that namespace
$namespace1 = $entry->getNameSpaces(true);
//Now we don't have the URL hard-coded
$domains = $entry->children($namespace1['domain']); 
$namespace2 = $domains->getNameSpaces(true);
$domainitems = $domains->children($namespace2['domain']);
foreach ($domainitems as $domain) {
	echo "Domain : " . $domain->name . "<br />";
	echo "Domain : " . $domain->reason . "<br />";
}
}

Glad you sorted it out.  I was in the process of replying when I saw your update.  Another way to access child elements would be:

$xml = new SimpleXMLElement($xmldata);
foreach ($xml->response->resData as $entry){
  $namespaces = $entry->getNameSpaces(true);
  $domain = $entry->children($namespaces['domain']);
  $cds = $domain->chkData->cd;
  foreach ($cds as $cd) {
        echo "$cd->name 
\n";
        echo "$cd->reason 
\n";
  }
}

Hello. Thanks for the reply. I quite like your coding as it's much shorter. I've just tested it and it works. Thank you!
