URGENT parsing xml file using codeigniter? - El Forum - 11-23-2010

[eluser]harper23[/eluser]
Hello all of you

Searching over internet I found http://blog.insicdesigns.com/2009/03/parsing-xml-file-using-codeigniters-simplexml-library/, but I have a lot of questions, I am new to codeigniter, and I am trying to adapt my code to this xml, I want to display once a user logins, but the question is How would I iterate through a series of child nodes with attributes?

my xml looks like this:

<?xml version="1.0" encoding="utf-8"?>
<Comprobante >

Here's a SimpleXML library I use to make this easier for you. Unzip it to your /application/libraries folder
Code:
//Load SimpleXML library
$this->load->library('simplexml');
$xmlData = $this->simplexml->xml_parse($xml); //where $xml is your xml to parse

var_dump($xmlData); //You should see an multi dimensional array for each node


Just loop through the appropriate arrays to access the data you need.

Thank you very much for your answers, so for loading the SimpleXML library is ok to put that code in welcome controller?, and for the xml is ok in the controller folder?

Bye and again thanks

Sure. I would keep the xml in another folder. Keep the folder logic of CI in tact. Perhaps (document root)/xml maybe more appropriate.

If the xml is a from another source (http or something), you could use curl to fetch the xml. I was using this method to fetch xml from the whitepages.com api.

Please use the code button in your editor, to format it properly. Without seeing how you are calling that method, I do notice that you may be leaving off a \\ from your $xmlfile string.
Try
Code:
$filename = $fname . '.xml';
$xmlfile  = "C:\\Users\\beto\\Documents\\xml\\" . $filename; //Adding extra slashes
$result   = '';

if(file_exists($xmlfile)){
  $xmlRaw = file_get_contents($xmlfile);

  $this->load->library('simplexml');
  $xmlData = $this->simplexml->xml_parse($xmlRaw);
  
  //foreach loop
}else{
  $result .= 'File ' . $xmlfile . ' was not found';
}
return $result;

Move the file out of your Documents folder. php is not able to read the file that is in your user folder. Folder/permissions prevent that. Move into a folder for all users or something under your document root (c:\wamp\www) or something.

Again please use the code button to paste code into your post.

I have tried the foloowing code.
Code:
$xml = file_get_contents($xmlfile);
$this->load->library('simplexml');
$xmlData = $this->simplexml->xml_parse($xml);
But it givs the error.
Quote:Unable to load the requested class: simplexml
Is it needed to download this library or it is builtin class in codeigniter libraries.
Thanx

PHP has changed quite since this thread. [url="http://www.php.net/manual/en/simplexml.examples-basic.php"]SimpleXML[/url] is part of PHP. I believe the simplexml library from the code above was just a wrapper to the actually PHP built in interface. Just read the example linked above, and just use the native PHP code instead of the library.
