LASTMOVE循环不工作

Question

我的XML看起来像

- <ItemMaster> 
    - <ItemMasterHeader> 
     + <ItemID> 
     + <ItemStatus> 
     + <UserArea> 
     - <Classification Type="HOMOLOGATION CLASS"> 
      - <Codes> 
      <Code>E</Code> 
      </Codes> 
     </Classification> 
     + <Classification Type="LP"> 
     + <Classification> 
     - <Classification Type="BRAND"> 
      - <Codes> 
       <Code>002</Code> 
      </Codes> 
     </Classification> 

YHE完整的XML是在这里http://www.speedyshare.com/MgCCA/download/ItemMaster-2.xml

我需要获取分类与属性TYPE =“品牌”的价值，但与下面的代码，它只取得属性TYPE =“HOMOLOGATION CLASS”的分类，我不想要，因为我要求“品牌”。我试图申请LASTMOVE，但剂量的工作。请告诉我我错在哪里。

我必须获取其他值也类似代码里面的类型 - “LP”也。

DECLARE rResource REFERENCE TO InputRoot.XMLNSC.*:SyncItemMaster.*:DataArea.*:ItemMaster.*:ItemMasterHeader[1]; 
     SET rowCnt = rowCnt+1;  
     DECLARE LineCount INTEGER 1; 

     WHILE LASTMOVE(rResource) = TRUE DO  
     SET OutputRoot.XMLNSC.root.row[rowCnt].product_Info.TyreBrandCd = THE (SELECT ITEM FIELDVALUE(T) FROM itemMaster.*:ItemMasterHeader[LineCount].*:Classification.*:Codes.*:Code AS T WHERE FIELDVALUE(itemMaster.*:ItemMasterHeader[LineCount].*:Classification.(XMLNSC.Attribute)Type) = 'BRAND'); 
      SET LineCount = LineCount + 1; 
     MOVE rResource NEXTSIBLING REPEAT TYPE NAME; 
     END WHILE;    
    RETURN TRUE; 
    END;

Answer 1

试试这个：

declare temp ROW; 

SET temp = THE (SELECT T.Classification FROM rResource AS T WHERE FIELDVALUE(T.Classification.(XMLNSC.Attribute)Type) = 'BRAND'); 

OutputRoot.XMLNSC.root.row[rowCnt].product_Info.TyreBrandCd = temp.code; 

Answer 2

我不知道你在找什么样的地图。假设你想要的是'代码'，在每个'ItemMasterHeader'上具有正确属性的'分类'中，出现在单独'行'文件夹内的输出中，这里是代码：

CREATE PROCEDURE ExtractTyreCodes() BEGIN 
     DECLARE rOutput REFERENCE TO OutputRoot; 
     DECLARE rResource REFERENCE TO InputRoot.XMLNSC.*:SyncItemMaster.*:DataArea.*:ItemMaster; 
     CREATE FIELD OutputRoot.XMLNSC.root AS rOutput; 
     IF LASTMOVE(rResource) THEN 
     SET rOutput.row[] = SELECT 
       THE(SELECT C.*:Codes.*:Code AS TyreBrand 
        FROM T.*:Classification[] AS C 
        WHERE C.(XMLNSC.Attribute)Type = 'BRAND') AS product_Info 
       FROM rResource.*:ItemMasterHeader[] AS T; 
     END IF; 
END; 

从这个消息开始：

<SyncItemMaster> 
    <DataArea> 
    <ItemMaster> 
     <ItemMasterHeader> 
     <ItemID/> 
     <ItemStatus/> 
     <UserArea/> 
     <Classification Type="HOMOLOGATION CLASS"> 
      <Codes> 
      <Code>E</Code> 
      </Codes> 
     </Classification> 
     <Classification Type="LP"/> 
     <Classification/> 
     <Classification Type="BRAND"> 
      <Codes> 
      <Code>002</Code> 
      </Codes> 
     </Classification> 
     </ItemMasterHeader> 
     <ItemMasterHeader> 
     <ItemID/> 
     <ItemStatus/> 
     <UserArea/> 
     <Classification Type="HOMOLOGATION CLASS"> 
      <Codes> 
      <Code>F</Code> 
      </Codes> 
     </Classification> 
     <Classification Type="LP"/> 
     <Classification/> 
     <Classification Type="BRAND"> 
      <Codes> 
      <Code>005</Code> 
      </Codes> 
     </Classification> 
     </ItemMasterHeader> 
    </ItemMaster> 
    </DataArea> 
</SyncItemMaster> 

你得到这个消息：

<root> 
    <row> 
    <product_Info> 
     <TyreBrand>002</TyreBrand> 
    </product_Info> 
    </row> 
    <row> 
    <product_Info> 
     <TyreBrand>005</TyreBrand> 
    </product_Info> 
    </row> 
</root> 

这会产生一个 '行' 文件夹的每个 'ItemMasterHeader'，把每一个 '产品的详细信息' F的内部年龄较大，并且在其中放置来自（属性）'类型'的'分类'='品牌'的代码。

希望这会有所帮助。问候，
