XSLT：基于多个标准计算特定节点

我有一些XML，我想将其转换为一个报告，显示在一个日期周期内匹配特定条件的节点数

下面是xml示例。我试图根据日期范围内的状态显示节点数

我可以根据日期范围进行匹配，但我无法显示该范围内的状态计数。欢迎指点

    <?xml version="1.0" encoding="UTF-8"?>
    <List>
     <Item>
       <Value name="Status">Open</Value>    
       <Value name="Date">2012-09-01</Value>
       <Value name="Name">Item 1</Value>
     </Item>
     <Item>
       <Value name="Status">Open</Value> 
       <Value name="Date">2012-10-15</Value>
       <Value name="Name">Item 2</Value>
     </Item>
     <Item>
       <Value name="Status">Open</Value> 
       <Value name="Date">2012-10-15</Value>
       <Value name="Name">Item 3</Value>
     </Item>
     <Item>
       <Value name="Status">Pending</Value> 
       <Value name="Date">2012-10-20</Value>
       <Value name="Name">Item 4</Value>
     </Item>
     <Item>
       <Value name="Status">Closed</Value>
       <Value name="Date">2012-10-30</Value>
       <Value name="Name">Item 5</Value>
     </Item>
    </List>

就这么简单：

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

 <xsl:param name="pStartDate" select="20121001"/>
 <xsl:param name="pEndDate" select="20121031"/>

 <xsl:template match="/">
   <xsl:variable name="vInRange" select=
    "/*/*[translate(Value[@name='Date'],'-','') >= $pStartDate
         and
          $pEndDate >= translate(Value[@name='Date'],'-','')
         ]"/>
     Open      <xsl:value-of select="count($vInRange[Value[@name='Status']='Open'])"/>
     Closed    <xsl:value-of select="count($vInRange[Value[@name='Status']='Closed'])"/>
     Pending   <xsl:value-of select="count($vInRange[Value[@name='Status']='Pending'])"/>
 </xsl:template>
</xsl:stylesheet>

 Open      2
 Closed    1
 Pending   1
