UPS API使用捲曲和PHP ...格式良好的XML問題

Question

UPS的服務器一直給我這樣的響應：

HTTP/1.1 200 OK 
Server: Apache 
Content-Length: 429 
X-Powered-By: Servlet/2.5 JSP/2.1 
Content-Type: application/xml 
Expires: Wed, 31 Aug 2011 21:28:12 GMT 
Cache-Control: max-age=0, no-cache, no-store 
Pragma: no-cache 
Date: Wed, 31 Aug 2011 21:28:12 GMT 
Connection: keep-alive 

與此錯誤：

<AddressValidationResponse> 
    <Response> 
     <TransactionReference> 
     <XpciVersion>1.0001</XpciVersion> 
     </TransactionReference> 
     <ResponseStatusCode>0</ResponseStatusCode> 
     <ResponseStatusDescription>Failure</ResponseStatusDescription> 
     <Error> 
     <ErrorSeverity>Hard</ErrorSeverity> 
      <ErrorCode>10001</ErrorCode> 
      <ErrorDescription>The XML document is not well formed</ErrorDescription> 
     </Error> 
    </Response> 
</AddressValidationResponse> 

這裏是PHP代碼中，我正在發送到服務器。是否有錯誤，我錯過了，忽略？

$data = '<?xml version=\"1.0\" ?> 
       <AccessRequest xml:lang=\"en-US\"> 
        <AccessLicenseNumber>$this->AccessLicenseNumber</AccessLicenseNumber> 
        <UserId>$this->UserId</UserId> 
        <Password>$this->Password</Password> 
       </AccessRequest> 
       <?xml version=\"1.0\" ?> 
       <AddressValidationRequest xml:lang=\"en-US\"> 
        <Request> 
         <TransactionReference> 
          <XpciVersion>1.0001</XpciVersion> 
         </TransactionReference> 
         <RequestAction>XAV</RequestAction> 
         <RequestOption>3</RequestOption> 
        </Request> 
        <AddressKeyFormat> 
         <AddressLine>$address</AddressLine> 
         <PoliticalDivision2>$city</PoliticalDivision2> 
         <PoliticalDivision1>$state</PoliticalDivision1> 
         <PostcodePrimaryLow>$zip</PostcodePrimaryLow> 
         <CountryCode>US</CountryCode> 
        </AddressKeyFormat> 
       </AddressValidationRequest>'; 

任何幫助將不勝感激。謝謝。

你必須使用"而不是'來包裝你的XML，像這樣：

$data="<?xml..."; 

PHP只"
