PHP - Simplexmlelement Object Help

Hi guys,

This prob is driving me nuts... Can someone please help?

Thanks in advance.

Hi Guys,

I'm trying to run the following code but the page breaks with no errors. I'm using PHP 5 which should run Simple XML. Code seems fine to me...

Code: [Select]
<?php
$xmlstr = "courses.xml";
$xml = new SimpleXMLElement($xmlstr); //  I Know it's breaking at this line

echo $xml->course[0]->name;
?>

Hey Guys,

I have a snippet of XML here..

Code: [Select]
<courses>
  <course>
    <id>70</id>
    <name>Marketing and Social Media</name>
    <dates>
      <date>
        <instance_id>6747</instance_id>
        <location />
        <course_type>Day</course_type>
        <date_available>2011/07/13</date_available>
        <time_start>9:30</time_start>
        <time_end>17:00</time_end>
        <availibility>7</availibility>
        <running_dates>
          <running_date>2011/07/13</running_date>
          <running_date>2011/07/14</running_date>
        </running_dates>
      </date>
    </dates>
  </course>
I'm trying to run xpath query to return all the courses and running dates associated with it but I dont understand how I get the running_dates?

This is what I have..

Code: [Select]

<?php

$xmlstr = "../wp-content/themes/iact/courses.xml";
$xml = new SimpleXMLElement($xmlstr, NULL, TRUE);


foreach ($xml->xpath('//date/running_dates') as $date) {

    $t = "<p class='heading'>". $date->course_type."</p>
          <div class='content'>".$date->running_date."</div>"; // do I need to go into another foreach here to loop all of the running dates? hardly?
    echo $t;
}
?>

Hello!
I am using CURL to access HTML and extract all the elements from it as below
Code: [Select]
**
* Initialize the cURL session
*/
$ch = curl_init();
/**
* Set the URL of the page or file to download.
*/
curl_setopt($ch, CURLOPT_URL,'http://www.w3schools.com/PHP/php_xml_simplexml.asp');
/**
* Ask cURL to return the contents in a variable
* instead of simply echoing them to the browser.
*/
          curl_setopt($ch, CURLOPT_FAILONERROR,1);
          curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);
          curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
          curl_setopt($ch, CURLOPT_TIMEOUT, 15);
/**
* Execute the cURL session
*/
$contents = curl_exec ($ch);

/**
* Close cURL session
*/
curl_close ($ch);


This works perfectly , but my next step is to use SimpleXMLElement() and grab a particular element from it which is.
Code: [Select]
$xml_data = new SimpleXMLElement($contents);

but I came across an article saying that there is no pint using SimpleXMLElement() to grab HTML Elements, Is that true?
and BTW if I need to  grab  a particular element (in the already extracted HTML using CURL) what is the function I am supposed to use ?

Thank you     

 

Hello, I'm in need of help. Sometimes my PHP reads XML from a ssh and it tends to fail at times.

Heres my complete error:

            }
        }else{
            return False;
        }
    }else{
        return False;

}

How would I full proof this from getting this error again, It seems to happen at completely random times.

I'm not very good with XML in PHP

Thanks!
