Isolar um texto em especifico no XML - Orientar XML com php

Olá pessoal, lá vem eu denovo com minhas perguntas, bom vamos lá, estou tendo um problema para orientar o XML para o local definido, não tenho ideia de onde começar nesse detalhe, consegui fazer um getElementsByTagName() para poder selecionar o XML que esta externamente.
O Seguinte código que estou usando é:

$xml_data=file_get_contents("http://IPDOSERVIDOR:8086/connectioncounts");
 $doc = new DOMDocument();
 $doc->loadXML($xml_data);
 $wms = $doc->getElementsByTagName('Stream');

 $assistindo = $wms->item(0)->getElementsByTagName("SessionsFlash")->item(0)->nodeValue;
 $passagemdepessoas = $wms->item(0)->getElementsByTagName("SessionsTotal")->item(0)->nodeValue;

O XML Externo deve imprimir um resultado igual a este:

>

O que desejo pegar neste xml é o que esta em destaque em vermelho, só que tenho que pega-lo pelo <name> que vou especificar para orientar ele, para assim eu poder pegar o SessionsFlash que é o código que desejo, vale lembrar que ele sempre terá um ou mais resultados dentro da tag <stream> só preciso alguma forma que possa selecionar esta parte e isolar ele para poder pegar os dados.

Alguem sabe como posso estar orientando desta forma o XML?

Agradeço desde já a participação de todos.
