解題

$xml_target_path = 'xml1.xml';
$feed = file_get_contents($xml_target_path);
$xml = new SimpleXmlElement($feed);

foreach ($xml-&gt;channel-&gt;item as $entry){
  $dc = $entry-&gt;children('http://purl.org/dc/elements/1.1/');
  echo $dc-&gt;creator-&gt;attributes()-&gt;ID;
}

$xml_target_path = 'xml1.xml';

$feed = file_get_contents($xml_target_path);

$xml = new SimpleXmlElement($feed);

foreach ($xml->channel->item as $entry){

$dc = $entry->children('http://purl.org/dc/elements/1.1/');

echo $dc->creator->attributes()->ID;

}

結果

解題

$xml_target_path = 'xml2.xml';
$feed = file_get_contents($xml_target_path);
$xml = new SimpleXmlElement($feed);

$elementType = $xml-&gt;children('uuid:AAAAA-120003-11231')-&gt;Schema-&gt;children('uuid:AAAAA-120003-11231')-&gt;ElementType;
foreach( $elementType-&gt;children('uuid:AAAAA-120003-11231') as $key ){
	$attr = $key-&gt;attributes();
	$datatype = $key-&gt;children('uuid:AAAAA-120003-11231')-&gt;datatype-&gt;attributes();
	echo sprintf(" Column =&gt; %s, DataType =&gt; %s
 ", $attr-&gt;name, $datatype-&gt;{'type'});
}

$rs = $xml-&gt;children('urn:schemas-microsoft-com:rowset');
foreach( $rs-&gt;data-&gt;children('#RowsetSchema') as $key){
	$attr = $key-&gt;attributes();
	echo sprintf(" %s =&gt; %s
 ", $attr-&gt;StudID, $attr-&gt;StudName);
}

$xml_target_path = 'xml2.xml';

$feed = file_get_contents($xml_target_path);

$xml = new SimpleXmlElement($feed);

$elementType = $xml->children('uuid:AAAAA-120003-11231')->Schema->children('uuid:AAAAA-120003-11231')->ElementType;

foreach( $elementType->children('uuid:AAAAA-120003-11231') as $key ){

$attr = $key->attributes();

$datatype = $key->children('uuid:AAAAA-120003-11231')->datatype->attributes();

echo sprintf(" Column => %s, DataType => %s

", $attr->name, $datatype->{'type'});

}

$rs = $xml->children('urn:schemas-microsoft-com:rowset');

foreach( $rs->data->children('#RowsetSchema') as $key){

$attr = $key->attributes();

echo sprintf(" %s => %s

", $attr->StudID, $attr->StudName);

}

結果

Column => StudID, DataType => string
Column => StudName, DataType => string
Column => ClassID, DataType => string
Column => Post, DataType => string
25-0001 => 楊同學
25-0002 => 曾同學
25-0003 => 姚同學
33-0001 => 張同學
33-0003 => 林同學
