replace an invalid URI in the .xml file - php

Question

how can i replace an invalid URI in xml file, i cannot parse the xml file because it gives an invalid URI error while trying to parse the file. How can i read the contents of the .xml file into a string so that the invalid URI can be replaced.
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<Submit xmlns="http://localhost/....">
<Order>
<Components>
<Component>
<ocode> ABC</ocode>
</Component>
</Components>
</Order>
</Submit>
</soap:Body>
</soap:Envelope>

If you just want the content, use SimpleXML and XPath to fetch the body contents...
$xml=simplexml_load_file("NewFile.xml");
$content = $xml->xpath("//soap:Body/*");
echo $content[0]->Order->asXML();
will give...
<Order>
<Components>
<Component>
<ocode> ABC</ocode>
</Component>
</Components>
</Order>
Not sure what the namespace http://localhost/.... is supposed to be, but it should be a valid URI - even if it is http://localhost.
Edit:
To try and fix the URI, you can read the file to a string first and then replace the invalid string with a valid one...
$data = file_get_contents("NewFile.xml");
$data = str_replace("http://localhost/....", "http://localhost", $data);
$xml=simplexml_load_string($data);
Or you could also try removing all of the attributes...
$data = preg_replace("/<Submit.*?>/", "<Submit>", $data);
