Hi every one,
 I have a simple variable comparison to be done in loop <xsl:for-each
and i have to compare a value from an xml document from a previous
value. I.e the xml tags might contain duplicates so i am comparing the
previous value from the current value to be converted into a pdf
document. I have two problems how do keep track of previous value
using a variable or other wise and how to use xsl choose i am doing
some thing like this.

 <xsl:variable name="PRGPIDP"  select="'jk'"/>
 <xsl:for-each select="itemMovementListsReport/
ItemMovementListsReportGroupEntry">

         <xsl:when test="$PRGPIDP eq PRGPID">
			            <fo:table-cell text-align="right"><fo:block><xsl:value-
of select="$PRGPIDP"/></fo:block></fo:table-cell>
			          </xsl:when>
			          <xsl:otherwise>
			            <fo:table-cell text-align="right"><fo:block><xsl:value-
of select="PRGPID"/></fo:block></fo:table-cell>
			          </xsl:otherwise>
			        </xsl:choose>

        <xsl:variable name="PRGPIDP" select="PRGPID"></xsl:variable>
            </xsl:for-each>

The variable i am using is also not being reset, can any one please
let me know any other ideas?
