xml webservice process into string??

[sdowney1]

this retrieves data from a webservice at Library of Congress

for example this here

http://www.loc.gov/standards/sru/simple.html

 

What I want to do is process the XML? into a string of usable text to put in a mysql database

Am I getting XML back or what?

save it and run it to see. In firefox, it shows xml headers, in chrome just the text elements.

// display the results in XML format

echo $results;

}//end of try

catch(Exception $e){echo $e->getMessage();exit();}

$xml = simplexml_load_string($result);

print_r($xml);
//print_r ($xmlarray);

?>

adding some code I can save the xml to a file

so maybe now can work with it

the file I found has to exist and have read and write permissions

   $filename = dirname(__FILE__)."/loc.xml";
   $raw_xml = file_get_contents($request);
   print $raw_xml;
   $fp = fopen($filename, "w");
   fwrite($fp, $raw_xml);
   fclose ($fp);

file_get_contents, does not work on the hosted site???

yet works locally on my localhost.

it will echo the $request

BUT NEVER returns anything for $raw_xml

$raw_xml = file_get_contents($request);

  echo $raw_xml;

 

I tried this on 2 hosted sites and it does not work.

It creates the file loc.xml, but it never has any contents 0 bytes

the file loc.xml has read - write permissions for everyone.

 

Anyone have a thought as to why this is happening?

 

 

$request='http://z3950.loc.gov:7090/voyager?version=1.1&operation=searchRetrieve&query=dinosaur&startRecord=2&maximumRecords=5';

 

echo $request;

 

  $filename = dirname(__FILE__)."/loc.xml";

  $raw_xml = file_get_contents($request);

  echo $raw_xml;

  $fp = fopen($filename, "w");

  fwrite($fp, $raw_xml);

  fclose ($fp);

well, It must be the free hosting service blocks web service calls

Does someone know of a free hosting service that allows web service calls?

 

any other ideas?
