php and xml coding help

[nbgoku]

How can I get it so the following work:

 

echo utf8_decode($xml->healings[0]->$xmla[0]->descrip[0]);    // NOT work

echo utf8_decode($xmlb);    // NOT work

 

<?php
  $xml    = simplexml_load_file('extra.xml');
  $xmla   = "test";
  $xmlb  = "$xml->healings[0]->".$xmla."[0]->descrip[0]";

  echo utf8_decode($xml->healings[0]->test[0]->descrip[0]);        // works

  echo utf8_decode($xml->healings[0]->$xmla[0]->descrip[0]);     // NOT work

  echo utf8_decode($xmlb);     // NOT work

?>

[exally]

echo utf8_decode($xml->healings[0]->$xmla[0]->descrip[0]);
to
echo utf8_decode($xml->healings[0]->xmla[0]->descrip[0]);

 

Without more information about the object etc, what are you hoping to achieve?

[exally]

"$xml->healings[0]->".$xmla."[0]->descrip[0]";

 

This might require that you use the function eval.

I suppose you don't want to hardcode the tag name. You might be changing it in the run time.

 

Try putting it in curly braces. 

echo utf8_decode({$xml->healings[0]->$xmla[0]->descrip[0] } );

 

Or else, another way could be to use a different XML parsing approach.
