RE: [xsl] Checking for nodes in other nodes

   Hi,
           You may want to try the following XSL. (Thanks to Bruce for
setting me on the right track).

<?xml version="1.0" encoding="utf-8" ?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:output method="xml" encoding="UTF-8" indent="yes"/>

<xsl:key name="equip" match="/Root/Equipment"
use="/Root/Equipment/Message/Field/EnumeratedType"/>

<xsl:template match="/Root">

<xsl:for-each select="/Root/EnumeratedType">

    <xsl:variable name="var" select="Name"/>

   <xsl:value-of select="count(key('equip', $var))"/>

    </xsl:for-each>

</xsl:template>

<xsl:template match="/Root/Equipment">

     <xsl:value-of select="."/>

</xsl:template>

</xsl:stylesheet>

   My input XML:

<Root>
<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>

<Equipment>
	<Name>Alternator</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>


</Root>

The stylesheet correctly produced the output 2.

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.

Thanks
