Compare Current Value to Preceeding Values

[redgrL86]

Hi,
I am trying to create an XSL document which will output the word "Header" only if the <StepRecipeID > string for the current step is not equal to the <StepRecipeID > from previous steps. Thus, for the XML below, the word "Header" should be output twice (once for each of the two steps in the XML) since each step has a different string value for the <StepRecipeID >. Likewise, if the <StepRecipeID > 's were the same strings, the output would only be one "Header".
Does anyone know how to do this with the XSL?? I am trying to use XPath code within the XSL but I don't know if that is correct and I can't seem to figure it out. Any help would be much appreciated!!

Thank you!
Christine


XSL Code:

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

<xsl:template match="/">

<xsl:for-each select="RecipeElement/Steps">

	<xsl:if test="'Step/StepRecipeID' != 'previous::*'">
		
		<t>Header </t>
	
	</xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

XML Code:

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="stylesheet13.xsl"?>
<RecipeElement>
<RecipeElementID>UFDF_CLEANING</RecipeElementID>
	<Steps>
		<InitialStep XPos="700" YPos="100">
			<Name>INITIALSTEP:1</Name>
		</InitialStep>
		<TerminalStep XPos="50" YPos="50">
			<Name>TERMINALSTEP:1</Name>
		</TerminalStep>
		
		<Step XPos="600" YPos="500" AcquireUnit="true">
			<Name>Step 1</Name>
			<StepRecipeID>StepOne</StepRecipeID>
			<UnitAlias>UFDF_CLEANING:1</UnitAlias>
		</Step>
		
		<Step XPos="600" YPos="1000" AcquireUnit="true">
			<Name>Step 2</Name>
			<StepRecipeID>StepTwo</StepRecipeID>
			<UnitAlias>UFDF_CLEANING:1</UnitAlias>
		</Step>
	</Steps>
</RecipeElement>
