的BizTalk平面文件产生CRLF即使空数据

Question

我有平面文件的XSD从XML映射的结果，像这样：

<?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> 

的问题是当XML有数据，我们有一个正确的结果，是这样的：

line1 
line2 
line3 
EOF 

但是，当我们没有数据（XML仅仅只有命名空间）

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

然后平面文件是：

CRLF (for easy reading) 
EOF 

我怎样才能从我的平面文件摆脱CRLF的，我只是想在EOF的第一道防线。

Answer 1

我刚试过你的模式，有一张地图，我没有映射任何东西到目的地，我没有得到CRLF。

所以问题出在你的地图上，而不是架构上。

如果没有数据，则需要添加一个链接到TransactionDate，以抑制该数据。
