arcxml 中 outputmode=”xml” 和 outputmode=”newxml” 的區別

   
   最近正在研究
   ArcXML_Programmers_Ref_Gd.pdf
   英語差，但也得啃啊。。
 
  outputmode="xml" 時
  request 
 

  <?xml version="1.0" encoding="UTF-8"?>
   <ARCXML version="1.1">
    <REQUEST> 
    <GET_FEATURES outputmode="newxml"> 
    <LAYER id="2" />
     <SPATIALQUERY subfields="state_name sub_region" where="STATE_NAME='Washington'" /> 
     </GET_FEATURES>
      </REQUEST> 
      </ARCXML>

respose<?xml version="1.0" encoding="UTF8"?> 
<ARCXML version="1.1"> 
<RESPONSE> <FEATURES>
 <FEATURE> 
 <FIELDS STATE_NAME="Washington" SUB_REGION="Pacific" />
  </FEATURE>
   <FEATURECOUNT count="1" hasmore="false" /> 
  </FEATURES>
   </RESPONSE> 
  </ARCXML>

 

  

 outputmode="newxml" 時
 request

  <?xml version="1.0" encoding="UTF-8"?>
   <ARCXML version="1.1">
    <REQUEST> 
    <GET_FEATURES outputmode="newxml"> 
    <LAYER id="2" />
     <SPATIALQUERY subfields="state_name sub_region" where="STATE_NAME='Washington'" /> 
     </GET_FEATURES>
      </REQUEST> 
      </ARCXML>

respose  <?xml version="1.0" encoding="UTF8"?>
       <ARCXML version="1.1"> 
       <RESPONSE> <FEATURES> 
       <FEATURE> 
       <FIELDS> 
       <FIELD name="STATE_NAME" value="Washington" />
       <FIELD name="SUB_REGION" value="Pacific" /> </FIELDS>
         </FEATURE> <FEATURECOUNT count="1" hasmore="false" /> 
         </FEATURES> </RESPONSE> </ARCXML>
         

 在用.net link 做開發時，好些時候要求用 newxml 格式
 
The "xml" outputmode can be used only when no XML parser is used since the attribute names in FIELD are always changing. When using an XML parser, outputmode should be set to "newxml", which returns data in a valid XML format. If outputmode="newxml", then all fields are returned using the FIELD element. The next request asks for the same information on Washington as the previous request.
這是原文。
