如何将数据从两个 SAS 数据集正确导出到一个 XML 数据文件？

如何解决如何将数据从两个 SAS 数据集正确导出到一个 XML 数据文件？

将多个（两个或多个）SAS 数据集（dataset1、dataset2）导出到一个 XML 数据文件并同时引用 XMLMap 中的不同表的正确方法是什么？

执行以下操作时效果很好：

filename xmlout 'path\to\file\want.xml';
libname xmlout xmlv2 xmltype=xmlmap xmlmap='path\to\file\XMLmap.map';

data xmlout.dim;
set work.have_dim;
run;

我从另一个 SAS 表中获取数据以在标题中导出（ID 和时间如 .map 中所示）。然后我会修改 .map ：

<OUTPUT> 
   <TABLEREF name="dim" /> 
   <TABLEREF name="header" />
</OUTPUT>

并执行以下代码：

data xmlout.header;
    set work.have_header;
run;

但是，我无法将 TABLEREF 添加到标题表中，因为它在文档中指定：TABLEREF= specifies the name of the table in the XMLMap to be exported. The name must be unique in the XMLMap definition,and the name must be a valid SAS name,which can be up to 32 characters. (cf. XML LIBNAME Engine )

所以我的问题是，如果我不能使用不同的 TABLEREF ，我如何将这两个 SAS 表导出到同一个 XML 文件中？在某些时候，我想使用一个数据步骤，我只是将两个表放在一起，并且在 .map 中只使用一个 TABLEREF，如下所示：

data aggregated;
   set have_dim have_header;
run;

但是，如何将某些变量重定向到 header 表（ID 和时间）以及 XML 输出中 dim 表中的其他变量？

所需的 XML output 将是：

<?xml version="1.0" encoding="UTF-8"?>
<ns2:message xmlns:ns2="http://www.someurl/common/vo/message" xmlns:ns3="http://www.someurl/common/vo/cube">
  <ns2:header>
      <ns2:ID>1234</ns2:ID> 
      <ns2:time>2021-01-19T09:20:47</ns2:time> <!-- the time of the day --> 
  </ns2:header>
  <ns2:content>
      <ns2:dataSegment id="OBSERVATION">
            <ns2:cube id="ID_CODE">
                <ns3:obs>
                    <ns3:dim name="CODE" value="ABC123" />
                    <ns3:dim name="VAR" value="VAR1"/>
                    <ns3:dim name="VALUE" value="Y"/>       
                    <ns3:dim name="DATE" value="2021-01-01T00:00:00" />
                </ns3:obs>
            </ns2:cube>
            <ns2:cube id="ID_CODE">
                <ns3:obs>
                    <ns3:dim name="CODE" value="DEF456" />
                    <ns3:dim name="VAR" value="VAR2"/>
                    <ns3:dim name="VALUE" value="N"/>       
                    <ns3:dim name="DATE" value="2021-01-01T00:00:00" />
                </ns3:obs>
            </ns2:cube>
        </ns2:dataSegment>
  </ns2:content>
</ns2:message>

为了举例，我只显示了 2 个观察结果。尽管如此，可能会有超过 100 万个观测值。

编辑：可重现的示例：

SAS Code：

data have_header;
ID = 1234;
time = datetime();
run;

data have_dim;
infile datalines delimiter=",";
input CODE :$8. VAR :$8. VALUE $1. DATE:datetime20.;
format DATE datetime20.;
datalines;
ABC1,VAR1,Y,31DEC2020:00:00:00
ABC2,VAR2,N,31DEC2020:00:00:00
;
run;

filename dim'path\to\file\dim.xml';
libname dim xmlv2 xmltype=xmlmap xmlmap='path\to\file\map_dim.map';

data dim.dim;
set have_dim;
run;

filename header 'path\to\file\header.xml';
libname header xmlv2 xmltype=xmlmap xmlmap='path\to\file\map_header.map';

data header.header;
set have_header;
run;

libname dim clear;
libname header clear;

*** COMBINE ALL XML FILES;
proc xsl 
   in  = "path\to\file\header.xml"
   xsl = "path\to\file\script.xsl"
   out = "path\to\file\final_output.xml";
run;

XML.map 表示暗淡：

解决方法

考虑 XSLT，这是一种专门用于转换 XML 文件的专用语言，例如从不同的文档进行组合。 SAS 可以使用 proc xsl 运行 XSLT 1.0 甚至 2.0。

然而，您实际上需要两个 XSLT 转换，因为您想要的输出并不完全是两个 XML 文件的堆栈，即 dim.xml 中的元素被迁移到属性。

XSLT 1 （另存为 .xsl 文件，一个特殊的 .xml 文件）

<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
                             xmlns:ns2="http://www.someurl/common/vo/message"
                             xmlns:ns3="http://www.someurl/common/vo/cube"> 
  <xsl:output indent="yes" encoding="UTF-8"/>
  <xsl:strip-space elements="*"/>
    
  <xsl:template match="/ns2:message">
    <ns2:message xmlns:ns2="http://www.someurl/common/vo/message" xmlns:ns3="http://www.someurl/common/vo/cube"> 
         <xsl:apply-templates select="ns2:content"/>
    </ns2:message>
  </xsl:template> 
 
   <xsl:template match="ns2:content">
    <xsl:copy> 
         <xsl:apply-templates select="ns2:dataSegment"/>
    </xsl:copy>
  </xsl:template> 
  
  <xsl:template match="ns2:dataSegment">
    <xsl:copy> 
         <xsl:attribute name="id">OBSERVATION</xsl:attribute>
         <xsl:apply-templates select="*"/>
    </xsl:copy>
  </xsl:template> 
  
  <xsl:template match="ns2:cube|ns3:obs">
     <xsl:apply-templates select="*"/>
  </xsl:template> 
  
  <xsl:template match="ns3:dim">
    <ns2:cube id="ID_CODE">
      <ns3:obs> 
         <xsl:for-each select="*">  
             <ns3:dim> 
                 <xsl:attribute name="name">
                    <xsl:value-of select="name()"/>
                 </xsl:attribute>
                 <xsl:attribute name="value">
                    <xsl:value-of select="text()"/>
                 </xsl:attribute>
            </ns3:dim>
         </xsl:for-each>
      </ns3:obs>     
     </ns2:cube>
  </xsl:template> 
  
</xsl:transform>

XSLT 2 （另存为 .xsl 文件；使用带有 file:// 关键字的绝对路径引用）

<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
                             xmlns:ns2="http://www.someurl/common/vo/message"> 
  <xsl:output indent="yes" encoding="UTF-8"/>
  <xsl:strip-space elements="*"/>
  
  <xsl:template match="/ns2:message">
    <ns2:message xmlns:ns2="http://www.someurl/common/vo/message" xmlns:ns3="http://www.someurl/common/vo/cube"> 
         <!-- COPY CURRENT DATA -->
         <xsl:copy-of select="*"/>

         <!-- COMBINE ALL DATA FROM NEW dim.xml -->
         <xsl:copy-of select="document('file://absolute/path/to/new_dim.xml')/ns2:message/*" />
    </ns2:message>
  </xsl:template> 
  
</xsl:transform>

SAS （使用宏输出多个文件）

*** OUTPUT INDIVIDUAL XML FILES;
%macro output_xmls(dset);
   filename xmlout "path\to\file\&dset..xml";
   libname xmlout xmlv2 xmltype=xmlmap xmlmap='path\to\file\XMLmap.map';

   data xmlout.&dset;
      set work.&dset;
   run;

   libname xmlout clear;
%mend output_xmls;

%output_xmls(header);
%output_xmls(dim);


*** TRANSFORM RAW dim.xml;
proc xsl 
   in  = "path\to\file\dim.xml"
   xsl = "path\to\file\script_1.xsl"
   out = "path\to\file\new_dim.xml";
run;

*** COMBINE header.xml and new_dim.xml FILES;
proc xsl 
   in  = "path\to\file\header.xml"
   xsl = "path\to\file\script_2.xsl"
   out = "path\to\file\final.xml";
run;

输出

<?xml version="1.0" encoding="UTF-8"?>
<ns2:message xmlns:ns2="http://www.someurl/common/vo/message"
             xmlns:ns3="http://www.someurl/common/vo/cube">
   <ns2:header>
      <ns2:ID>1234</ns2:ID>
      <ns2:time>2021-01-19T09:39:44</ns2:time>
   </ns2:header>
   <ns2:content>
      <ns2:dataSegment id="OBSERVATION">
         <ns2:cube id="ID_CODE">
            <ns3:obs>
               <ns3:dim name="CODE" value="ABC1"/>
               <ns3:dim name="VAR1" value="VAR1"/>
               <ns3:dim name="VALUE" value="Y"/>
               <ns3:dim name="DATE" value="2020-12-31T00:00:00"/>
            </ns3:obs>
         </ns2:cube>
         <ns2:cube id="ID_CODE">
            <ns3:obs>
               <ns3:dim name="CODE" value="ABC2"/>
               <ns3:dim name="VAR1" value="VAR2"/>
               <ns3:dim name="VALUE" value="N"/>
               <ns3:dim name="DATE" value="2020-12-31T00:00:00"/>
            </ns3:obs>
         </ns2:cube>
      </ns2:dataSegment>
