I have been struggling for days to determine how to take an XML file

  • 0

I have been struggling for days to determine how to take an XML file of game results (teams and final scores) and generate a team standings list that shows each team along with how many times they won, lost or tied. The results should also be sorted by total wins, but I can’t even figure out a good method of calculating the wins/losses let alone sorting by the results. I know it must involve muenchian grouping, and I’ve coded the part that finds all distinct teams but am stumped where to go from there. Any help would be GREATLY appreciated.

    You want something like this (XSLT 1.0):

    <xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:key name="kTeamByName" match="Home|Away" use="."/>

 <xsl:template match="/*">

 <table border="1">
  <tr>
   <td>Team</td><td>W</td><td>D</td><td>L</td>
  </tr>
      <xsl:apply-templates select=
      "(*/Home | */Away)
        [generate-id()
        =
         generate-id(key('kTeamByName', .)[1])
        ]
      ">
      <xsl:sort data-type="number" order="descending" select=
       "count(key('kTeamByName', .)
                 [self::Home
                and
                  ../Home_Score > ../Away_Score
                or
                  self::Away
                and
                  ../Away_Score > ../Home_Score
                 ]
             )
       "/>

      </xsl:apply-templates>
  </table>
 </xsl:template>

 <xsl:template match="Home|Away">
  <tr>
   <td>
    <xsl:value-of select="."/>
   </td>
   <td>
    <xsl:value-of select=
    "count(key('kTeamByName', .)
                 [self::Home
                and
                  ../Home_Score > ../Away_Score
                or
                  self::Away
                and
                  ../Away_Score > ../Home_Score
                 ]
             )"/>
   </td>
   <td>
    <xsl:value-of select=
    "count(key('kTeamByName', .)
                 [../Home_Score = ../Away_Score]
             )"/>
   </td>
   <td>
    <xsl:value-of select=
    "count(key('kTeamByName', .)
                 [self::Home
                and
                  ../Away_Score > ../Home_Score
                or
                  self::Away
                and
                  ../Home_Score > ../Away_Score
                 ]
             )"/>
   </td>
  </tr>
 </xsl:template>

 <xsl:template match="text()"/>
</xsl:stylesheet>

    when this transformation is applied on the provided XML document:

    <Games>
    <Game>
        <Home>Team A</Home>
        <Away>Team B</Away>
        <Home_Score>20</Home_Score>
        <Away_Score>15</Away_Score>
    </Game>
    <Game>
        <Home>Team C</Home>
        <Away>Team D</Away>
        <Home_Score>12</Home_Score>
        <Away_Score>18</Away_Score>
    </Game>
    <Game>
        <Home>Team A</Home>
        <Away>Team C</Away>
        <Home_Score>8</Home_Score>
        <Away_Score>8</Away_Score>
    </Game>
    <Game>
        <Home>Team B</Home>
        <Away>Team D</Away>
        <Home_Score>6</Home_Score>
        <Away_Score>14</Away_Score>
    </Game>
    <Game>
        <Home>Team D</Home>
        <Away>Team C</Away>
        <Home_Score>9</Home_Score>
        <Away_Score>11</Away_Score>
    </Game>
    <Game>
        <Home>Team C</Home>
        <Away>Team A</Away>
        <Home_Score>13</Home_Score>
        <Away_Score>13</Away_Score>
    </Game>
</Games>

    the wanted, correct result is produced:

    <table border="1">
   <tr>
      <td>Team</td>
      <td>W</td>
      <td>D</td>
      <td>L</td>
   </tr>
   <tr>
      <td>Team D</td>
      <td>2</td>
      <td>0</td>
      <td>1</td>
   </tr>
   <tr>
      <td>Team A</td>
      <td>1</td>
      <td>2</td>
      <td>0</td>
   </tr>
   <tr>
      <td>Team C</td>
      <td>1</td>
      <td>2</td>
      <td>1</td>
   </tr>
   <tr>
      <td>Team B</td>
      <td>0</td>
      <td>0</td>
      <td>2</td>
   </tr>
</table>
