Joe,
I'm making up some data to show something similar; it may be instructive to
work/adapt it to your needs:
This input (note that machine-3 uses B twice):
<data>
<enums>
<enum>A</enum>
<enum>B</enum>
</enums>
<machines>
<machine name="machine-1">
<value>A</value>
</machine>
<machine name="machine-2">
<value>A</value>
</machine>
<machine name="machine-3">
<value>B</value>
<value>B</value>
</machine>
</machines>
</data>
And this XSL:
<?xml version="1.0" encoding="iso8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:key match="machine" name="k-machines-per-enum" use="value"/>
<xsl:template match="data">
<xsl:copy>
<xsl:apply-templates select="enums/enum"/>
</xsl:copy>
</xsl:template>
<xsl:template match="enum">
<enum value="{.}">
<xsl:attribute name="usecount">
<xsl:value-of select="count(key('k-machines-per-enum',
.))"/>
</xsl:attribute>
</enum>
</xsl:template>
</xsl:stylesheet>
Yields this, each enum and the number of machines in which it is used:
<?xml version="1.0" encoding="UTF-8"?>
<data>
<enum value="A" usecount="2"/>
<enum value="B" usecount="1"/>
</data>
The idea, then, is that as you generate a common header with those enums
whose usage count is greater than 1. Also, when you generate a specific C
file, include those enums whose [unique] usage count, for that machine is 1.

Given the following XML
<EnumeratedType>
<Name>Speed Type</Name>
<Enumeration>
<Name>Low</Name>
<Value>1</Value>
</Enumeration>
<Enumeration>
<Name>Med</Name>
<Value>5</Value>
</Enumeration> <Enumeration>
<Name>High</Name>
<Value>8</Value>
</Enumeration>
</EnumeratedType>
<Equipment>
<Name>Motor</Name>
<Message>
<Name>Motor Speed</Name>
<Field>
<Name>MotorID</Name>
<DataType>integer</DataType>
</Field>
<Field>
<Name>Speed<Name >
<DataType>Enumerated Type</DataType>
<EnumeratedType>Speed Type</EnumeratedType>
</Field>
</Message/
</Equipment>
What I need to be able to determine is if an enumerated type is used in
more than one equipment. (The XSL is used to generate C code, and each
equipment is generated to a different file. If the type is used in
multiple pieces of equipment then it should be generated to a
"common_types.h" file, if it is only used by ne piece of equipment then
it should be generated in that equipment's file)
Currently I can use the same .xsl to generate the different files, using
a command line parameter, however, all of the enumerated types are
generates to all files at this point. I'm pretty noob and cluless about
xslt, so I don't even know where to begin to attempt this part of the
task.
