I need to parse an xml file in order to display an attribute based on a key value. For example, in the file below I would like to extract realTimeIid and email for each session however I’m having a difficult time getting my code to work due to the fact that there are multiple elements for each varValue with the same attributes.

Here is my code using DOMDocument. My desired results should return two rows as follows.
Sessionid|email
4306650378 address1@myexample.com
4306650379 address2@myexample.com
I only want the email address and not all of the other elements and attributes under varValue->getAttribute(‘name’). The problem with this is that it returns all of the attributes and I don’t know how to look for just email and get the subsequent value.
$doc = new DOMDocument();
$doc->load( 'C:/Dev/report.xml' );
$sessions = $doc->getElementsByTagName( "Session" );
foreach( $sessions as $session )
{
$sessionid = $session->getAttribute( 'realTimeID' );
$values = $session->getElementsByTagName( "VarValues" );
foreach( $values as $value)
{
$varValues = $value->getElementsByTagName( "varValue" );
foreach( $varValues as $other )
{
$email = $other->getAttribute('name');
echo "$sessionid- $email\n";
}}}
I’ve always found SimpleXML to be really easy to work with:
