Re: 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[@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[@startNum>= $localStart and @endNum&lt;= $localEnd]"/>
to simply formulate the condition with XPath.
