You wouldn't. Not with SimpleXML anyway. SimpleXML takes an XML file
or string and converts it into an object. In RDF, however, XML
entities' names contain colons, which are illegal in PHP variable
names. You could try and replace colons with underscores, so you
would get something like this:
$RDF = file_get_contents('install.rdf');
$RDF = str_replace('RDF:', 'RDF_', $RDF);
$RDF = str_replace('em:', 'em_', $RDF);
$XML = simplexml_load_string($RDF);
foreach ($XML->RDF_Description as $num => $description) {
$attributes = $description->attributes();
if (isset($attributes['em_id'])) {
echo "ID = {$attributes['em_id']}; version =
{$attributes['em_version']}";
}
}
Best regards,
