Maybe try <xsl:number from="preceding-sibling::Category" ... ?

Hi All,

Here is my input XML:

<?xml version="1.0" encoding="UTF-8"?>
<Cases>
     <Story>
         <Category>Category: Subcategory</Category>
         <CaseTitle>Title One</CaseTitle>

         <Author>Authors One</Author>
         <History>History One</History>
         <DifferentialDiagnosis>Sick</DifferentialDiagnosis>

         <TeachingPoint>Point1</TeachingPoint>
         <TeachingPoint>Point2</TeachingPoint>
         <Category>Category One: Subcategory</Category>
         <CaseTitle>Title Two</CaseTitle>
         <Institution>Title Two</Institution >
         <Author>Author Two</Author>
         <History>History Two</History>
         <DifferentialDiagnosis>Sick</DifferentialDiagnosis>
         <DifferentialDiagnosis>Sicker</DifferentialDiagnosis>

         <TeachingPoint>Point1</TeachingPoint>
         <TeachingPoint>Point2</TeachingPoint>
     </Story>
</Cases>

I want to organize the data in a deeper structure like this:

<?xml version="1.0" encoding="UTF-8"?>
<data>
    <newRecord>
       <Category>Category</Category>
       <Subcategory>Subcategory</Subcategory>
       <Case>1</Case>
       <CaseTitle>Title One</CaseTitle>
       <Institution>Institution One</Institution>
       <Author>Authors One</Author>
       <History>History One</History>
       <DifferentialDiagnosis>Sick</DifferentialDiagnosis>
       <DifferentialDiagnosis>Sicker</DifferentialDiagnosis>
       <DifferentialDiagnosis>Sickest</DifferentialDiagnosis>
       <TeachingPoint>Point1</TeachingPoint>
       <TeachingPoint>Point2</TeachingPoint>
    </newRecord>
    <newRecord>
       <Category>Category One</Category>
       <Subcategory>Subcategory</Subcategory>
       <Case>2</Case>
       <CaseTitle>Title Two</CaseTitle>
       <Institution>Title Two</Institution>
       <Author>Author Two</Author>
       <History>History Two</History>
       <DifferentialDiagnosis>Sick</DifferentialDiagnosis>
       <DifferentialDiagnosis>Sicker</DifferentialDiagnosis>
       <DifferentialDiagnosis>Sickest</DifferentialDiagnosis>
       <TeachingPoint>Point1</TeachingPoint>
       <TeachingPoint>Point2</TeachingPoint>
    </newRecord>
</data>

With help from the list, I am using this to get the results.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output indent="yes" />
<xsl:template match="Cases/Story">
<data>
<xsl:apply-templates select="Category[1]" />
</data>
</xsl:template>
<xsl:template match="Category">
<xsl:element name="newRecord">
<Category><xsl:value-of select="substring-before(.,':
')"/></Category>
<Subcategory><xsl:value-of select="substring-after(.,':
')"/></Subcategory>
<Case><xsl:number count="Category"/></Case>
<xsl:apply-templates
select="following-sibling::*[1][not(self::Category)]"
mode="in-case-siblings"/>
</xsl:element>
<xsl:apply-templates select="following-sibling::Category[1]"/>
</xsl:template>
<xsl:template match="*" mode="in-case-siblings">
<xsl:copy-of select="." />
<xsl:apply-templates
select="following-sibling::*[1][not(self::Category)]"
mode="in-case-siblings"/>
</xsl:template>
<xsl:template match="Category" mode="in-case-siblings"/>

</xsl:stylesheet>

This is working well, but now I need to do something different to the
<DifferentialDiagnosis> elements. I want to change the element names by
numbering them sequentially within my <newRecord> element, like this:

<?xml version="1.0" encoding="UTF-8"?>
<data>
    <newRecord>
       <Category>Category</Category>
       <Subcategory>Subcategory</Subcategory>
       <Case>1</Case>
       <CaseTitle>Title One</CaseTitle>
       <Institution>Institution One</Institution>
       <Author>Authors One</Author>
       <History>History One</History>
       <DifferentialDiagnosis1>Sick</DifferentialDiagnosis1>
       <DifferentialDiagnosis2>Sicker</DifferentialDiagnosis2>
       <DifferentialDiagnosis3>Sickest</DifferentialDiagnosis3>
       <TeachingPoint>Point1</TeachingPoint>
       <TeachingPoint>Point2</TeachingPoint>
    </newRecord>
    <newRecord>
       <Category>Category One</Category>
       <Subcategory>Subcategory</Subcategory>
       <Case>2</Case>
       <CaseTitle>Title Two</CaseTitle>
       <Institution>Title Two</Institution>
       <Author>Author Two</Author>
       <History>History Two</History>
       <DifferentialDiagnosis1>Sick</DifferentialDiagnosis1>
       <DifferentialDiagnosis2>Sicker</DifferentialDiagnosis2>
       <DifferentialDiagnosis3>Sickest</DifferentialDiagnosis3>
<TeachingPoint>Point1</TeachingPoint>
       <TeachingPoint>Point2</TeachingPoint>
    </newRecord>
</data>

I added this rule to my stylesheet:

     <xsl:template match="DifferentialDiagnosis" mode="in-case-siblings">
         <xsl:variable name="diagnosis"><xsl:number
count="DifferentialDiagnosis" from="Category"/></xsl:variable>
         <xsl:element name="{concat(name(),$diagnosis)}"><xsl:value-of
select="."/></xsl:element>
         <xsl:apply-templates
             select="following-sibling::*[1][not(self::Category)]"
mode="in-case-siblings"/>
     </xsl:template>

This basically "works" except the numbers are sequential throughout the
document.

<data>
    <newRecord>
	...
       <DifferentialDiagnosis1>Sick</DifferentialDiagnosis1>
       <DifferentialDiagnosis2>Sicker</DifferentialDiagnosis2>
       <DifferentialDiagnosis3>Sickest</DifferentialDiagnosis3>
	...
    </newRecord>
    <newRecord>
	...
       <DifferentialDiagnosis1>Sick</DifferentialDiagnosis5>
       <DifferentialDiagnosis2>Sicker</DifferentialDiagnosis6>
       <DifferentialDiagnosis3>Sickest</DifferentialDiagnosis7>
	...
    </newRecord>
</data>

I need the numbers to reset for each <newRecord> element. I am sorry for the
long post, but I want to be complete as possible. Also, for this project, I
need to use XSLT 1.0. Thank you very much.
