Hi Ahmad,
I'm still not sure I understand well it seems from your answer that a character's
"moves" are according to document order (the time a message was sent is not the time
a character delivered it), so here's a possible solution:
1. Change the definition of the "kLocByCharacter" to:
<xsl:key name="kLocByCharacter"
match="LOCATION_ID[not(.
=
../preceding-sibling::DIRECT[1]
/LOCATION_ID)
]"
use="../CHARACTER_ID"/>
2. The key "kLocByValandChar" is no-longer needed -- may be removed.
3. The end of the stylesheet should now be:
<xsl:value-of select="$NL"/>
<xsl:value-of select="concat('Room moves by character:', $NL)"/>
<xsl:for-each select="$vUniqueCharactersSending">
<xsl:value-of select="concat('Character_ID: ',
CHARACTER_ID,
':',
$NL
)"/>
<xsl:for-each select="key('kLocByCharacter',CHARACTER_ID)">
<xsl:value-of select="concat(' ', ., $NL)"/>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Bellow is the complete stylesheet:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="text"/>
<xsl:key name="kByID" match="DIRECT" use="CHARACTER_ID"/>
<xsl:key name="kByTargetID" match="TARGET_CHARACTER_ID" use="."/>
<xsl:key name="kLocByCharacter"
match="LOCATION_ID[not(.
=
../preceding-sibling::DIRECT[1]
/LOCATION_ID)
]"
use="../CHARACTER_ID"/>
<xsl:key name="kLocByValandChar"
match="LOCATION_ID"
use="concat(., '|', ../CHARACTER_ID)"/>
<xsl:variable name="vUniqueCharactersSending"
select="LOG/DIRECT[generate-id()
=
generate-id(key('kByID',
CHARACTER_ID
)[1]
)
]"/>
<xsl:variable name="vUniqueCharactersReceiving"
select="LOG/DIRECT/TARGET_CHARACTER_ID
[generate-id()
=
generate-id(key('kByTargetID',
.
)[1]
)
]"/>
<xsl:variable name="vNumCharactersSending"
select="count($vUniqueCharactersSending)"/>
<xsl:variable name="vNumCharactersReceiving"
select="count($vUniqueCharactersReceiving)"/>
<xsl:variable name="vTotalSent"
select="count(LOG/DIRECT/CHARACTER_ID)"/>
<xsl:variable name="NL" select="'
'"/>
<xsl:template match="/">
<xsl:for-each select="$vUniqueCharactersSending">
<xsl:value-of select="concat('CHARACTER_ID ',CHARACTER_ID,
' sent ',
count(key('kByID',CHARACTER_ID)),
' messages, received ',
count(key('kByTargetID',CHARACTER_ID)),
$NL
)"/>
</xsl:for-each>
<xsl:for-each select="$vUniqueCharactersReceiving
[not(key('kByID', .))]">
<xsl:value-of select="concat('CHARACTER_ID ', .,
' sent 0 messages, received ',
count(key('kByTargetID',.)),
$NL
)"/>
</xsl:for-each>
<xsl:value-of select="$NL"/>
<xsl:value-of select="concat('Number of characters having sent a message: ',
$vNumCharactersSending,
$NL
)"/>
<xsl:value-of select="concat('Number of characters having received a message: ',
$vNumCharactersReceiving,
$NL
)"/>
<xsl:value-of select="$NL"/>
<xsl:value-of select="concat('Total sent: ',
$vTotalSent,
', Average sent by a sending character: ',
$vTotalSent div $vNumCharactersSending,
'
',
'Total received: ',
$vTotalSent,
', Average received by a receiving character: ',
$vTotalSent div $vNumCharactersReceiving,
'
'
)"/>
<xsl:value-of select="$NL"/>
<xsl:value-of select="concat('Room moves by character:', $NL)"/>
<xsl:for-each select="$vUniqueCharactersSending">
<xsl:value-of select="concat('Character_ID: ',
CHARACTER_ID,
':',
$NL
)"/>
<xsl:for-each select="key('kLocByCharacter',CHARACTER_ID)">
<xsl:value-of select="concat(' ', ., $NL)"/>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
