xsl: How to update varial value in a loop

maxin

I have a xml file:

Expand|Select|Wrap|Line Numbers

 
<E1MBXYI SEGMENT="1">

...

<CHARG>1000024187</CHARG> 

...

</E1MBXYI>

<E1MBXYI SEGMENT="1">

...

<CHARG>1000024187</CHARG> 

...

</E1MBXYI>

<E1MBXYI SEGMENT="1">

...

<CHARG>1000024188</CHARG> 

...

</E1MBXYI>

I want to transform it to another xml file, where I should only take the item CHARG if it has a differetn value.
I wrote the following code:

Expand|Select|Wrap|Line Numbers

 
<DataArea>

        <xsl:variable name="V_MaterialLot" select="''"/>

        <xsl:for-each select="E1MBXYI">

                <xsl:if test="$V_MaterialLot != CHARG">

                        <MaterialInformation>

                                <ID>

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

                                        <xsl:variable name="V_MaterialLot" select="CHARG"/>

                                <ID>

                        <MaterialInformation>

                </xsl:if>

        </xsl:for-each>

</DataArea>

However, I can not define the varial V_MaterialLot twice in the same xsl.
Does someone have a solution to me?

if you want to use only the unique <CHARG>s, then you can try Muenchian Grouping before doing the output.

More specifically it would be like:

Expand|Select|Wrap|Line Numbers

 
<xsl:for-each select="E1MBXYI[not (CHARG = preceding-sibling::E1MBXYI/CHARG)]">

No variables needed.

Thanks all for the solution.
I will try it.
