With the DOM extension it should be something like this:

$dom = new DOMDocument;
$dom->validateOnParse = TRUE;
$dom->loadXML($xmlString); // or use ->load('file.xml')
$node = $dom->getElementById('foo');
echo $node->nodeValue;

See the manual on

If it doesn't work with getElementById (which usually only happens if the DTD doesn't know the id attribute), you can still use XPath to do the query:

$xpath = new DOMXPath($dom);
$nodes = $xpath->query('//Message[@id = "foo"]');
foreach($nodes as $node) {
    echo $node->nodeValue;
}

Unlike getElementById, an XPath query always returns a DOMNodeList. It will be empty if the query didn't find any nodes.

If the ID is a real XML ID, you can also use the id() function in XPath

$xpath = new DOMXPath($dom);
$nodes = $xpath->query('id("foo")');
foreach($nodes as $node) {
    echo $node->nodeValue;
}

See Simplify PHP DOM XML parsing - how? for more details on XML IDs.

For SimpleXML this should do the trick:

$xml = simplexml_load_file($xmlFileLoc);
foreach ($xml->Message as $msg)
{
    echo $msg['Id'];
}

Use SimpleXML:

$xml = simplexml_load_file($grabUrl);
foreach ($xml->Message as $message) {
    echo $message->attributes()->Id.'<br />';
}

Or use XMLReader, with which you can miss memory leaks when processing large XMLs.

$xml = new XMLReader;
$xml->open($grabUrl);
while ($xml->read()) {
    if ($xml->nodeType === XMLReader::ELEMENT && $xml->name == 'Message')
        echo $xml->getAttribute('Id');
}
