XSLT: Breaking CSV aus einer Quelle XML-Knoten in mehrere Ziel-XML-Knoten

Question

Dank der Hilfe von Kollegen SO, die mir in this question half ich bin auf halbem Weg durch meine XML-Transformation.

Das Problem, das ich gegen eine Wand mit Komma getrennt Werte Transformation (DATE und Menge):

<?xml version="1.0" encoding="utf-8"?> 
<results> 
<recordset rowCount="68" fieldNames="ITEM,ECL,LEAD_TIME,QTY,DATE" type="**coldfusion.sql.QueryTable**"> 
<field name="ITEM"> 
<string>ITEM_A</string> 
<string>ITEM_B</string> 
<string>ITEM_C</string> 
</field> 
<field name="REV"> 
<string>A</string> 
<string>B</string> 
<string>C</string> 
</field> 
<field name="LEAD_TIME"> 
<string>10</string> 
<string>15</string> 
<string>25</string> 
</field> 

<field name="QTY"> 
<string>10,13,3</string> 
<string>1,5,2</string> 
<string>6,10,25</string> 
</field> 

</recordset> 
<var name="DATE_LABELS"> 
<string>05-18,05-25,06-01</string> 
</var> 
</results> 

In:

<records> 
<item_line> 
<item>ITEM_A</item> 
<rev>A</rev> 
<lead_time>10</lead_time> 
<values> 
    <qty date="05-18>10</qty> 
    <qty date="05-25>13</qty> 
    <qty date="06-01>3</qty> 
</values> 
</item_line> 
<item_line> 
<item>ITEM_B</item> 
<rev>B</rev> 
<lead_time>15</lead_time> 
<values> 
    <qty date="05-18>1</qty> 
    <qty date="05-25>5</qty> 
    <qty date="06-01>2</qty> 
</values> 
</item_line> 
<item_line> 
<item>ITEM_C</item> 
<rev>C</rev> 
<lead_time>25</lead_time> 
<values> 
    <qty date="05-18>6</qty> 
    <qty date="05-25>10</qty> 
    <qty date="06-01>25</qty> 
</values> 
</item_line> 
</records> 

Ist es überhaupt möglich, es mit XSLT auszudrücken?

Ich beginne den Mann zu hassen, dass „entworfen“ die Quelle XML-Schema ...

UPDATE: Vielen Dank für Ihre Hilfe!

ich die Lösung aktualisiert habe ich auf Ihre andere Frage zur Verfügung gestellt:

<xsl:stylesheet version="1.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 

    <xsl:output indent="yes"/> 

    <xsl:template match="/"> 
    <records> 
     <!-- Just process the first field's children, to get the list of line items --> 
     <xsl:apply-templates select="/results/recordset/field[1]/*"/> 
    </records> 
    </xsl:template> 

      <!-- Convert each field child to a line item --> 
      <xsl:template match="field/*"> 
      <item_line> 
       <!-- Then query all the fields for the value at this position --> 
       <xsl:apply-templates select="/results/recordset/field"> 
       <xsl:with-param name="pos" select="position()"/> 
       </xsl:apply-templates> 
      </item_line> 
      </xsl:template> 

        <xsl:template match="field"> 
        <xsl:param name="pos"/> 
        <!-- Convert the field name to lower case --> 
        <xsl:element name="{translate(@name,'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 
                 'abcdefghijklmnopqrstuvwxyz')}">

        </values> 
        </xsl:template> 

    <xsl:template mode="qty" match="field/*"> 
    <!-- ASSUMPTION: date-list and value-list will have same number of commas --> 
    <xsl:param name="date-list" select="/results/var[@name = 'DATE_LABELS']/string"/>

    <!-- Extract the date -->

    </xsl:variable> 
    <!-- Output the element --> 
    <qty date="{$date}"> 
     <xsl:value-of select="$value"/> 
    </qty> 
    <!-- Keep processing if there are more left --> 
    <xsl:if test="contains($date-list,',')"> 
     <xsl:apply-templates mode="qty" select="."> 
     <xsl:with-param name="date-list" select="substring-after($date-list, ',')"/> 
     <xsl:with-param name="value-list" select="substring-after($value-list, ',')"/> 
     </xsl:apply-templates> 
    </xsl:if> 
    </xsl:template> 

      <xsl:template name="next-item"> 
      <xsl:param name="csv"/> 
      <xsl:choose> 
       <xsl:when test="contains($csv, ',')"> 
       <xsl:value-of select="substring-before($csv, ',')"/> 
       </xsl:when> 
       <xsl:otherwise> 
       <xsl:value-of select="$csv"/> 
       </xsl:otherwise> 
      </xsl:choose> 
      </xsl:template> 

</xsl:stylesheet> 

Lassen Sie mich wissen, wenn Sie Fragen haben.

Vielleicht können Sie dieses Stück Kuchen das nächste Mal in einer Frage stellen, also müssen wir die Dinge nicht zweimal machen, aber hier sind wir!
