XML/PHP API Question! Solved one part need help with selecting!

Hello,
I've managed to recieve all messages from Ebay within the data range I specified with the call GetMemberMessages (http://developer.ebay.com/DevZone/XM...rMessages.html) but I have one problem left I really need help with.

Here is the code I used:
PHP: Select all

<?php   
include('functions.php');
include(
'variables.php');
error_reporting(E_ALL);
ini_set('display_errors''1');
    
//SiteID must also be set in the Request's XML
    //SiteID = 0  (US) - UK = 3, Canada = 2, Australia = 15, ....
    //SiteID Indicates the eBay site to associate the call with
    
$siteID 0;
    
//the call being made:
    
$verb 'GetMemberMessages';
    
//Regulates versioning of the XML interface for the API
    
$compatabilityLevel 433;

    
//get an array of strings containing the required headers
    
$headers buildEbayHeaders($devID$appID$certID$compatabilityLevel$siteID$verb);

    
// Time from and time to
    
$time_from date('Y-m-d\TH:i:s',strtotime("-10 days")).'.799Z';
    
$time_to date('Y-m-d\TH:i:s',strtotime("+ 1 day")).'.799Z';
    
    
///Build the request Xml string
    
$requestXmlBody '<?xml version="1.0" encoding="utf-8">';
    
$requestXmlBody .= '<GetMemberMessagesRequest xmlns="urn:ebay:apis:eBLBaseComponents">';
    
$requestXmlBody .= "<RequesterCredentials><eBayAuthToken>$userToken</eBayAuthToken></RequesterCredentials>";
    
$requestXmlBody .= "<MailMessageType>All</MailMessageType>";
    
$requestXmlBody .= "<EndCreationTime>$time_to</EndCreationTime>";
    
$requestXmlBody .= "<StartCreationTime>$time_from</StartCreationTime>";
    
$requestXmlBody .= '</GetMemberMessagesRequest>';
    
    
$responseXml sendHttpRequest($requestXmlBody$serverUrl$headers);
    if(
stristr($responseXml'HTTP 404') || $responseXml == '')
        die(
'<P>Error sending request');
    
    
//Xml string is parsed and creates a DOM Document object
    
$responseDoc domxml_open_mem($responseXml);
    
    
//get any error nodes
    
$errors $responseDoc->get_elements_by_tagname('Errors');
    
    
//if there are error nodes
    
if(count($errors) > 0)
    {
        echo 
'<P><B>eBay returned the following error(s):</B>';
        
//display each error
        //Get error code, ShortMesaage and LongMessage
        
$code $errors[0]->get_elements_by_tagname('ErrorCode');
        
$shortMsg $errors[0]->get_elements_by_tagname('ShortMessage');
        
$longMsg $errors[0]->get_elements_by_tagname('LongMessage');
        
//Display code and shortmessage
        
echo '<P>'$code[0]->get_content(), ' : 'str_replace(">""&gt;"str_replace("<""&lt;"$shortMsg[0]->get_content()));
        
//if there is a long message (ie ErrorLevel=1), display it
        
if(count($longMsg) > 0)
            echo 
'<BR>'str_replace(">""&gt;"str_replace("<""&lt;"$longMsg[0]->get_content()));

    }
    else 
//no errors
    
{
     
//get results nodes
    
$itemNodes $responseDoc->get_elements_by_tagname('MemberMessage');
    
    foreach(
$itemNodes as $item){
    
$message $item->get_elements_by_tagname('MemberMessageExchange');
                {
                
//display all the elements of each item
                
foreach($item->child_nodes() as $itemChild)
        echo 
$itemChild->get_content();
        
            }
    
    
    }
    
    }
?>
The problem is that when I run that code I get all information back - everything - item numbers, emails, questions and everything else. I've no idea of how to select the information I want to use. That's what I really need help with.

I tried to use echo $itemChild->get_content('SenderEmail'); to get only the sender email but it didn't work, I still got everything back. I'm really greatful for any help I can get.

Thanks in advance,
Oskar R

Re: XML/PHP API Question! Solved one part need help with selecting!

Hi Oskar

Code: Select all
foreach($item->child_nodes() as $itemChild)
       echo $itemChild->get_content();
 
           }
$item is the membermessage so when you do $item->child_nodes you'll get the lot. I don't know the datastructure of <MemberMessage> and what element(s) you want. You need a method which selects by tag name. In fact in your code you have just this only it isn't doing anything there:

Code: Select all
$message = $item->get_elements_by_tagname('MemberMessageExchange');
you could try replacing the block I copied at the top of this post with this where 'Email' is the name of the element you want:

Code: Select all
foreach($item->get_elements_by_tagname('Email') as $itemChild)
       echo $itemChild[0]->get_content();
 
           }
I'm not sure if this will work. get_elements_by_tagname returns a list of matching nodes. I would expect this to be just one hence the [0] on the echo line.
I'm happy to help you more but I would need to see if poss the XML for MemberMessage and to know which field(s) you want

It looks like the PHP XMLDOM does not support XPATH which would have solved the problem very easily.
