我試過不同的技巧，但他們不工作。

 
    $xmlResponse = simplexml_load_string($output); 
print_r($xmlResponse); 
    $totalPages = $xmlResponse->PaginationResult->TotalNumberOfPages; 
echo "there are $totalPages pages"; 

    $feedback = $xmlResponse->FeedbackDetailArray; 
print_r($feedback); 

    foreach($feedback as $rows) 
    { 

$username = $rows->FeedbackDetail; 
echo $username->CommentingUser; 
}

的XML看起來像這樣

<?xml version="1.0" encoding="UTF-8"?> 
`<GetFeedbackResponse xmlns="urn:ebay:apis:eBLBaseComponents"><Timestamp>2011-08-01T08:39:00.631Z</Timestamp><Ack>Success</Ack><Version>731</Version>` `<Build>E731_INTL_BUNDLED_13551333_R1</Build><FeedbackDetailArray><FeedbackDetail><CommentingUser>amangi-machque</CommentingUser>`<CommentingUserScore>141</CommentingUserScore><CommentText>YAAAAAA!</CommentText><CommentTime>2011-08-01T08:38:16.000Z</CommentTime><CommentType>Positive</CommentType><ItemID>120420154018</ItemID><Role>Seller</Role><FeedbackID>540473547022</FeedbackID><TransactionID>744712455002</TransactionID><OrderLineItemID>120420154018-744712455002</OrderLineItemID><ItemTitle>NEW Keyspan High Speed USB Serial Adapter USA-19HS</ItemTitle><ItemPrice currencyID="USD">29.6</ItemPrice></FeedbackDetail><FeedbackDetail><CommentingUser>kerryd53</CommentingUser><CommentingUserScore>124</CommentingUserScore>`

嘗試用：

foreach ($xmlResponse -> FeedbackDetailArray -> FeedbackDetail as $row) 
{ 
    echo $row -> CommentingUser; 
}

好吧，如果你的XML看起來是這樣的（我不太從上面的代碼瞭解結構）：

<comments> 
    <comment> 
    <commentingUser>user1</commentingUser> 
    </comment> 
    <comment> 
    <commentingUser>user2</commentingUser> 
    </comment> 
</coments>

你可以這樣讀：

foreach($xmlResponse->comment as $comment) { 
    echo $comment->commentingUser; 
}

看起來你指的是XML對象內部的錯誤的元素，試試這個：

$feedback = $xmlResponse->FeedbackDetailArray->FeedbackDetail; 
foreach($feedback as $row)

不工作。我之前也這樣做過...... – Michael

如果你只是要需要CommentingUser元素，你可以也做一個xpath查詢來獲取它們。

foreach ($xmlResponse->xpath('CommentingUser') as $user) { 
    echo $user; 
}
