can't view report phpjasperxml

[eluser]Unknown[/eluser]
i've something problem with report phpjasperxml

i've make name file controllers : mydata.php

I also have followed the following ways :

Code:

Copy PHPJasperXML.inc to application/libraries.
Rename the file to PHPJasperXML.php.
Copy the folder fpdf to application/libraries.
Insert the following line to PHPJasperXML.php after the <?php tag:
include_once('./fpdf/FPDF.php');

You should now be able to load the library in your controller using
$this->load->library('PHPJasperXML');

view code:
controllers : mydata.php

Code:

function report()
    {
        $this->load->library('fpdf/fpdf.php');
        $this->load->library('PHPJasperXML');
        
        $xml =  simplexml_load_file('mydata.jrxml'); ---> Line Number 115


        @$PHPJasperXML = new PHPJasperXML();
        @$PHPJasperXML->debugsql=false;
        @$PHPJasperXML->arrayParameter=$arrayParameters;
        @$PHPJasperXML->xml_dismantle($xml);

        @$PHPJasperXML->transferDBtoArray('localhost','root','','dbbmhskr');
        @$PHPJasperXML->outpage("I");    //page output method I:standard output  D:Download file
            
    }

message error:

Code:

A PHP Error was encountered

Severity: Warning

It looks to me like you probably need to provide the correct path to mydata.jrxml.
