small question to simplexml

[dexters]

Hi,

I have a small question regarding simplexml in php5. Imagine following code

<?php

$test = <<<XML
<?xml version="1.0" encoding="iso-8859-1"?>
<a>
  <b>
    <c>
      text
      <d/>
    </c>
  </b>
</a>
XML;

$xml = simplexml_load_string( $test );

?>

What I would like to get, is the 'text' value. I tried

print_r($xml->b->c->nodeValue);
print_r($xml->b->c);

But both don't give me the required value :bemused:

Any idea?

Best regards,
Dexter

I don't know simpleXml, but I know XML. The document you have is not a xml document, it is missing a start tag to match <d>. I don't know if that is the problem, but it could be.

Fix the above, and if it still doesn't work try xpath. There is good tutorials at www.w3schools.com about xml, xslt and xpath, use them to get the basics.

Hi Piranha,

I have to correct you on this, because the example given above is valid XML. You can check it here http://www.w3schools.com/dom/dom_validate.asp.

It uses the special empty element tag. So <d/> is in fact the same as <d></d>. You can read about it here http://www.w3.org/TR/xml/#sec-starttags.

I tried xpath as well, but it doesn't give me the result either:

print_r($xml->xpath('/a/b/c'));

Any more ideas?

Best regards,
Andre

Yes, you are right about that. I must have imagined that the slash was before d and not after. Sorry about that.

Unfortunatley I don't have any suggestion that I think should work. print_r should do the work, but just to be sure use a while-loop like the one in the manual page.

echo $xml->b->c; worked for me.

<?php

$test = <<<XML
<?xml version="1.0" encoding="iso-8859-1"?>
<a>
  <b>
    <c>
      text
      <d/>
    </c>
  </b>
</a>
XML;

$xml = simplexml_load_string( $test );
echo $xml->b->c;
?>
