Answer 1

You can try below code for SimpleXML
<?php
$xml ='<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<SubmitLeadResponse xmlns="https://test.com/">
<SubmitLeadResult>
<Result>C</Result>
<RedirectURL>https://testred.com</RedirectURL>
<ApplicantID>123</ApplicantID>
<ConfirmedPrice>0</ConfirmedPrice>
<PotentialPrice>0</PotentialPrice>
</SubmitLeadResult>
</SubmitLeadResponse>
</soap:Body>
</soap:Envelope>';
$get_xml = str_ireplace(['SOAP-ENV:', 'SOAP:'], '', $xml);
$xml = simplexml_load_string($get_xml);
print"<pre>";
print_r((string)$xml->Body->SubmitLeadResponse->SubmitLeadResult->RedirectURL);
echo "<br /><br /><br />";
print_r($xml);
?>

I've changed your code a bit. Here's a working sample to get the RedirectURL:
<?php
$xmlstr = '<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<SubmitLeadResponse xmlns="https://test.com/">
<SubmitLeadResult>
<Result>C</Result>
<RedirectURL>https://testred.com</RedirectURL>
<ApplicantID>123</ApplicantID>
<ConfirmedPrice>0</ConfirmedPrice>
<PotentialPrice>0</PotentialPrice>
</SubmitLeadResult>
</SubmitLeadResponse>
</soap:Body>
</soap:Envelope>';
$doc = new DOMDocument();
$doc->loadXML( $xmlstr );
$RedirectURL = $doc->getElementsByTagName( "RedirectURL" );
$RedirectURL = $LoginResults->item(0)->nodeValue;
var_dump( $RedirectURL );
Sample provided from this source: There are also more informations to reading SOAP-envelopes without a soapclient
Please note that it's good practice to omit the php closing tag and stay in the php-context as long as possible to avoid unexpected outputs (linebreaks).

Your XML contains namespaced elements, so it's a little more complicated to parse. It can be done by passing the namespace values to children() like so:
Codepad demo
$SubmitLeadResponse = new SimpleXMLElement($xmlstr);
echo (string)$SubmitLeadResponse
->children('http://schemas.xmlsoap.org/soap/envelope/')
->Body
->children('https://test.com/')
->SubmitLeadResponse
->SubmitLeadResult
->RedirectURL;
Outputs
https://testred.com
Note: SimpleXML doesn't like new lines before the XML string, so remove the new line, making it:
$xmlstr = '<?xml version="1.0" encoding="utf-8"?>
