的BizTalk平面文件產生CRLF即使空數據

Question

我有平面文件的XSD從XML映射的結果，像這樣：

<?xml version="1.0" encoding="utf-16"?> 
<xs:schema xmlns="http://mynamespace" xmlns:b="http://schemas.microsoft.com/BizTalk/2003" targetNamespace="http://mynamespace" xmlns:xs="http://www.w3.org/2001/XMLSchema">

          <!-- My elements here -->

        </xs:sequence> 
       </xs:complexType> 
       </xs:element> 
      </xs:sequence> 
      </xs:complexType> 
     </xs:element> 
     <xs:element minOccurs="1" maxOccurs="1" default="EOF" name="EOF" type="xs:string"> 
      <xs:annotation> 
      <xs:appinfo> 
       <b:fieldInfo sequence_number="2" justification="left" pos_offset="0" pos_length="3" /> 
      </xs:appinfo> 
      </xs:annotation> 
     </xs:element> 
     </xs:sequence> 
    </xs:complexType> 
    </xs:element> 
</xs:schema> 

的問題是當XML有數據，我們有一個正確的結果，是這樣的：

line1 
line2 
line3 
EOF 

但是，當我們沒有數據（XML僅僅只有命名空間）

<ns:SAPFile Channel="Eziemall" xmlns:ns="http://mynamespace" /> 

然後平面文件是：

CRLF (for easy reading) 
EOF 

我怎樣才能從我的平面文件擺脫CRLF的，我只是想在EOF的第一道防線。

Answer 1

我剛試過你的模式，有一張地圖，我沒有映射任何東西到目的地，我沒有得到CRLF。

所以問題出在你的地圖上，而不是架構上。

如果沒有數據，則需要添加一個鏈接到TransactionDate，以抑制該數據。
