XSL分组使用attibute

Question

我有一些XML，看起来有点像这样：

<Options> 
    <Option OptionGroup="Safety">Driver Airbag</Option> 
    <Option OptionGroup="Comfort and Convenience">Front Electric Windows</Option> 
    <Option OptionGroup="Comfort and Convenience">Height Adjustable Drivers Seat</Option> 
    <Option OptionGroup="Comfort and Convenience">Pollen Filter</Option> 
    <Option OptionGroup="Comfort and Convenience">Privacy Glass</Option> 
    <Option OptionGroup="Comfort and Convenience">Remote Boot Release</Option> 
    <Option OptionGroup="Comfort and Convenience">Split Rear Seats</Option> 
    <Option>Something else</Option> 
    <Option>Yet another thing</Option> 
    <Option OptionGroup="Paint or Trim and Upholstery">Metallic Paint</Option> 
    <Option OptionGroup="Exterior Equipment">Power Assisted Steering (PAS)</Option> 
    <Option OptionGroup="Interior Equipment">Leather Steering Wheel</Option> 
    <Option OptionGroup="In Car Entertainment">CD Radio</Option> 
    <Option OptionGroup="Security">Central Locking</Option> 
</Options> 

我想组一起使用XSL 1.0输出，根据他们的选项组attirbute，有没有任何选项最后列出的属性。是这样的：

<table> 
<tr><th>Safety</th></tr> 
    <tr><td>Drivers Airbag</td></tr> 
<tr><th>Comfort and Convenience</th></tr> 
    <tr><td>Front Electric Windows, Height Adjustable Drivers Seat, Pollen Filter, Privacy Glass, Remote Boot Release, Split Rear Seats</td></tr> 
<tr><th>Paint or Trim and Upholstery</th></tr> 
    <tr><td>Metallic Paint</td></tr> 
<tr><th>Exterior Equipment</th></tr> 
    <tr><td>Power Assisted Steering (PAS)</td></tr> 
<tr><th>Interior Equipment</th></tr> 
    <tr><td>CD Radio</td></tr> 
<tr><th>Security</th></tr> 
    <tr><td>Central Locking</td></tr> 
<tr><th>Other</th></tr> 
    <tr><td>Something else, Yet another thing</td></tr> 
</table> 

我猜这是所有可能的，但不能解决它。任何帮助将非常感激地收到。

谢谢。

这应该工作：

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

    <xsl:template match="/"> 
    <table> 
     <xsl:for-each select="Options/Option/@OptionGroup[not(. = preceding::Option/@OptionGroup)]"> 
     <xsl:call-template name="OutputGroup"> 
      <xsl:with-param name="title" select="." /> 
      <xsl:with-param name="items" select="../../Option[@OptionGroup = current()]" /> 
     </xsl:call-template> 
     </xsl:for-each> 

     <xsl:if test="Options/Option[not(@OptionGroup)]"> 
     <xsl:call-template name="OutputGroup"> 
      <xsl:with-param name="title" select="'Other'" /> 
      <xsl:with-param name="items" select="Options/Option[not(@OptionGroup)]" /> 
     </xsl:call-template> 
     </xsl:if> 
    </table> 
    </xsl:template> 
    <xsl:template name="OutputGroup"> 
    <xsl:param name="title" /> 
    <xsl:param name="items" /> 

    <tr> 
     <th> 
     <xsl:value-of select="$title"/> 
     </th> 
    </tr> 
    <tr> 
     <td> 
     <xsl:apply-templates select="$items" /> 
     </td> 
    </tr> 

    </xsl:template> 

    <xsl:template match="Option"> 
    <xsl:if test="position() > 1"> 
     <xsl:text>, </xsl:text> 
    </xsl:if> 
    <xsl:value-of select="."/> 
    </xsl:template>

这里是一个grouping sample：

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

<xsl:param name="default" select="'Other'"/> 

<xsl:output method="html" indent="yes"/> 

<xsl:key name="ogroup" match="Option" use="string(@OptionGroup)"/> 

<xsl:template match="Options"> 
    <table> 
    <xsl:apply-templates select="Option[@OptionGroup][generate-id() = generate-id(key('ogroup', string(@OptionGroup))[1])]" mode="term"/> 
    <xsl:apply-templates select="key('ogroup', '')[1]" mode="term"/> 
    </table> 
</xsl:template> 

<xsl:template match="Option" mode="term"> 
    <tr> 
    <th> 
     <xsl:choose> 
     <xsl:when test="@OptionGroup"> 
      <xsl:value-of select="@OptionGroup"/> 
     </xsl:when> 
     <xsl:otherwise><xsl:value-of select="$default"/></xsl:otherwise> 
     </xsl:choose> 
    </th> 
    <td> 
     <xsl:apply-templates select="key('ogroup', string(@OptionGroup))"/> 
    </td> 
    </tr> 
</xsl:template> 

<xsl:template match="Option"> 
    <xsl:if test="position() &gt; 1">, </xsl:if> 
    <xsl:value-of select="."/> 
</xsl:template> 

</xsl:stylesheet> 

它把

<Options> 
    <Option OptionGroup="Safety">Driver Airbag</Option> 
    <Option OptionGroup="Comfort and Convenience">Front Electric Windows</Option> 
    <Option OptionGroup="Comfort and Convenience">Height Adjustable Drivers Seat</Option> 
    <Option OptionGroup="Comfort and Convenience">Pollen Filter</Option> 
    <Option OptionGroup="Comfort and Convenience">Privacy Glass</Option> 
    <Option OptionGroup="Comfort and Convenience">Remote Boot Release</Option> 
    <Option OptionGroup="Comfort and Convenience">Split Rear Seats</Option> 
    <Option>Something else</Option> 
    <Option>Yet another thing</Option> 
    <Option OptionGroup="Paint or Trim and Upholstery">Metallic Paint</Option> 
    <Option OptionGroup="Exterior Equipment">Power Assisted Steering (PAS)</Option> 
    <Option OptionGroup="Interior Equipment">Leather Steering Wheel</Option> 
    <Option OptionGroup="In Car Entertainment">CD Radio</Option> 
    <Option OptionGroup="Security">Central Locking</Option> 
</Options> 

到

<table> 
    <tr> 
     <th>Safety</th> 
     <td>Driver Airbag</td> 
    </tr> 
    <tr> 
     <th>Comfort and Convenience</th> 
     <td>Front Electric Windows, Height Adjustable Drivers Seat, Pollen Filter, Privacy Glass, Remote Boot Release, Split Rear Seats</td> 
    </tr> 
    <tr> 
     <th>Paint or Trim and Upholstery</th> 
     <td>Metallic Paint</td> 
    </tr> 
    <tr> 
     <th>Exterior Equipment</th> 
     <td>Power Assisted Steering (PAS)</td> 
    </tr> 
    <tr> 
     <th>Interior Equipment</th> 
     <td>Leather Steering Wheel</td> 
    </tr> 
    <tr> 
     <th>In Car Entertainment</th> 
     <td>CD Radio</td> 
    </tr> 
    <tr> 
     <th>Security</th> 
     <td>Central Locking</td> 
    </tr> 
    <tr> 
     <th>Other</th> 
     <td>Something else, Yet another thing</td> 
    </tr>
