Answer 1

First thing, your XML file is not well-formed. The root tag is <searchresult> while the last tag is </search-result>. This causes a parsing error.
Second thing, if your tags contain dashes, those tags cannot be used directly as variables with SimpleXML, in that case you should use a special syntax (see this: php simplexml_load_file with a dash ( - )). Other way to fix this is, if you control de XML syntax, change the way the XML is written and don't use dashes on tags.
Lastly, I think you want to print out the info of files within the result-files tag.
$xml = simplexml_load_file("file.xml");
foreach ($xml->{'result-files'}->file as $file) {
printFile($file);
}
function printFile($file) {
$name = trim($file->name);
$url = trim($file->url);
print "$name $url\n";
}
Output:
file 1 http://www.example.com
file 2 http://www.example.com
And you are done.

You're creating an object when you use the simplexml_load_file. The object isn't necessarily iterable - but it is indexable by tag names. try not doing the foreach(...) and instead just using echo $xml->name;. If that doesn't work, then perhaps you're looking in the wrong directory for your file. You likely need to do something like:
EDITED TO MATCH XML FILE PROVIDED
$path = $_SERVER['DOCUMENT_ROOT']."/file.xml";
$xml = simplexml_load_file($path);
echo $xml->start; //should output 20
