[xsl] Concatenate and unique values
Subject: [xsl] Concatenate and unique values|

SymptomNum is sequential from 0 till the number of rows of data. Each row has SymptomNum, Pulse and Heart-beat. Across all the SymptomNum, I want to find the unqiue combinations of Pulse and Heart-beat existing in the data. There may be repitions, so I want to ignore them.
<xsl:variable name="current-sym-num" select="./SymptomNum"/>
<xsl:variable name="pulse-val" select="./Pulse"/>
<xsl:variable name="heart-beat-val" select="./HeartBeat"/>
<xsl:variable name="sym-summary" select="concat($pulse-val, ' ', $heart-beat-val)"/>
<!-- Display all unique combinations of pulse-val and heart-beat-val -->
<xsl:if test="$pulse-val and $heart-beat-val">
How do i find that this current combination of pulse-val and heart-beat-val is unique?
I have been using this logic to get unique values of pulse values:
<xsl:variable name="unique-pulse-num" select="//Health/Disease/Pulse[not(.=following::Pulse)]" />
<xsl:value-of select="." />,
Can this logic be extended to multiple attributes of an element? Can anyone help me with this logic? Thanks in advance,
