Re: [xsl] double document merge using keys

Okay, when I try this template, I get unusual return.


<xsl:variable name="stand2page" select="document('teks2page2.xml')"/>

<xsl:template match="chapter">
       <xsl:for-each select="Chapterlesson">
        <xsl:copy>
            <xsl:copy-of select="@*"/>
            <xsl:apply-templates/>
            <xsl:variable name="localStart" select="startNum"/>
            <xsl:variable name="localEnd" select="endNum"/>
            <xsl:for-each select="$stand2page">
                 <range><xsl:copy-of 
select="$stand2page/standards/stand[(_at_)startNum &gt;= $localStart and 
@startNum &lt;= $localEnd]"/></range>
             </xsl:for-each>
      </xsl:copy>
     </xsl:for-each>
</xsl:template>


Everything is good until we get to the triple digits:
<Chapterlesson code="6.1.2">
      <ch>1</ch>
      <lesson>Collaborating Through the Writing Process </lesson>
      <startNum>13</startNum>
      <endNum>32</endNum>
      <range>
         <stand startNum="13" endNum="14">14.A.2</stand>

         <!--I removed a bunch from here-->

         <stand startNum="30" endNum="30">14.D.3</stand>
         <stand startNum="31" endNum="31">14.E.3</stand>
         <stand startNum="132" endNum="132">16.A.2</stand>
         <stand startNum="133" endNum="133">14.A.1</stand>
                <!--many more like thes-->
</range>
</Chapterlesson>

Something is going wrong with the math. Is it seeing startNum="133" and seeing 
13 or something?

I have a set of standards that need to be aligned with each lesson. The 
standards are coded to the page, not the lesson. Here is a snippet of the 
current xml of standardDoc.xml:
<standards>
  <stand startNum="5" endNum="5">19.A.4</stand>
  <stand startNum="11" endNum="11">14.D.2</stand>
  <stand startNum="11" endNum="11">14.D.3</stand>
  <stand startNum="13" endNum="14">14.A.2</stand>
  <stand startNum="15" endNum="15">14.A.1</stand>
  <stand startNum="16" endNum="16">14.A.1</stand>
....
</standards>
The following stylesheet works as far as it goes. It only captures the 
standards that match the start page of the lesson. What I need is way to 
address standards with startNum >= $localStart and <= $localEnd. Is there a 
way to do this using keys?

<xsl:template match="Chapterlesson">
       <xsl:copy>
           <xsl:copy-of select="@*"/>
           <xsl:apply-templates/>
           <xsl:variable name="localStart" select="startNum"/>
           <xsl:variable name="localEnd" select="endNum"/>
           <xsl:for-each select="$stand2page">
               <stand><xsl:copy-of select="key('standPage', 
$localStart)"/></stand>
           </xsl:for-each>

I am not sure the a key helps with a less than/greater than condition but you 
could certainly use e.g.
             <xsl:copy-of select="$stand2page/standards/stand[(_at_)startNum 
= $localStart and @endNum &lt;= $localEnd]"/>
to simply formulate the condition with XPath.
