xpath：从xml

Question

无法获得所需的输出......也许它不可能，但我是XPath选择器的新手。

我有XML：

<submission>
    <component type="X">
        <audit>
            <measures>
                <measure id="xyz">
                    <reported>false</reported>
                    <benefit>false</benefit>
                    <data-elements>
                        <data-element id="rate1">
                            <reportable>false</reportable>
                            <comment/>
                        </data-element>
                        <data-element id="rate2">
                            <reportable>false</reportable>
                            <comment/>
                        </data-element>
                        <data-element id="rate3">
                            <reportable>false</reportable>
                            <comment/>
                        </data-element>
                        <data-element id="rate4">
                            <reportable>false</reportable>
                            <comment/>
                        </data-element>
                    </data-elements>
                </measure>
                <measure id="abc">
                    <reported>false</reported>
                    <benefit>false</benefit>
                    <data-elements>
                        <data-element id="rate5">
                            <reportable>false</reportable>
                            <comment/>
                        </data-element>
                        <data-element id="rate6">
                            <reportable>false</reportable>
                            <comment/>
                        </data-element>
                        <data-element id="rate7">
                            <reportable>false</reportable>
                            <comment/>
                        </data-element>
                        <data-element id="rate8">
                            <reportable>false</reportable>
                            <comment/>
                        </data-element>
                    </data-elements>
                </measure>
            </measures>
        </audit>
    </component>
</submission>

我试图使用像这样的XMLMAP使用XPath选择器访问属性：

<?xml version="1.0" ?>
<SXLEMAP version="1.2">
  <TABLE name="AUDIT">  
    <TABLE-PATH syntax="XPath">  
       /submission/component/audit/measures/measure
     </TABLE-PATH>

    <COLUMN name="MEASURE" retain="YES">  
      <PATH syntax="XPath">  
         /submission/component/audit/measures/measure@id
        </PATH>
        <TYPE>character</TYPE>
        <DATATYPE>STRING</DATATYPE>
        <LENGTH>30</LENGTH>
     </COLUMN>

    <COLUMN name="RATES">  
      <PATH syntax="XPath">  
       //submission/component/audit/measures/measure/data-elements/data-element/@id
        </PATH>
        <TYPE>character</TYPE>
        <DATATYPE>STRING</DATATYPE>
        <LENGTH>20</LENGTH>
     </COLUMN>

    <COLUMN name="REPORT">  
      <PATH syntax="XPath">  
       /submission/component/audit/measures/measure/data-elements/data-element/reportable
        </PATH>
        <TYPE>character</TYPE>
        <DATATYPE>STRING</DATATYPE>
        <LENGTH>20</LENGTH>
     </COLUMN>

我的输出如下：

   MEASURE                           RATES                   REPORT

   xyz                               rate4                   false
   abc                               rate8                   false

我希望我的输出获得所有费率，而不仅仅是最后一个费率，例如：

   MEASURE                           RATES                   REPORT

   xyz                               rate1                   false
   xyz                               rate2                   false
   xyz                               rate3                   false
   xyz                               rate4                   false
   abc                               rate5                   false
   abc                               rate6                   false
   abc                               rate7                   false
   abc                               rate8                   false

这可能使用XMLMAP还是需要其他东西？

提前感谢您的意见！

****编辑****************************************** *****;

这是一个基本的SAS程序，它将xml拉入并打印输出：

* set destination for output *;
LIBNAME DATA '<filepath>';

* set location of xml document and xml_map *;
LIBNAME XFILE XML '<filepath>\stack_example.xml' 
          XMLMAP='<filepath>\stack_import_map.xml';


* check import *;
PROC PRINT DATA= XFILE.AUDIT;
RUN;

Answer 1

我明白了......

在我的表格路径中，我需要深入到我希望开始新观察（行）的行级别，例如：

studentDict

现在将选择我想要的所有数据元素。
