Is it possible to "key" on two values during a document merge? Let me explain.
I have document that includes lesson name and the page range of the lesson:
Writing with Power
Pages 5–12
Collaborating Through the Writing Process
Pages 13–32
I have transformed the information into the following xml:
<chapter>
<Chapterlesson code="6.1.1">
<ch>1</ch>
<lesson>Writing with Power </lesson>
<startNum>5</startNum>
<endNum>12</endNum>
</Chapterlesson>
<Chapterlesson code="6.1.2">
<ch>1</ch>
<lesson>Collaborating Through the Writing Process </lesson>
<startNum>13</startNum>
<endNum>32</endNum>
</Chapterlesson>
...
</chapter>
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 <= $localEnd. Is there a way
to do this using keys?
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:variable name="stand2page" select="document('stand2page.xml')"/>
<xsl:key name="standPage" match="stand" use="@startNum"/>
<xsl:template match="Chapterlesson">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
<xsl:variable name="localStart" select="startNum"/>
<xsl:variable name="localEnd" select="endNum"/>
<xsl:for-each select="$stand2page">
<stand><xsl:copy-of select="key('standPage',
$localStart)"/></stand>
</xsl:for-each>
</xsl:copy>
</xsl:template>
