I've just recently figured out how to make the Muenchian method work
and I've run into a problem that I figured out a way to hack around. It
seems rather inelegant so I'm wondering if there's a better way.
I've got an external reference data source that has all of the people in my department and their associate (truncated for simplicity) <people> <staff staff_id="unique_id_here" alpha_key="A"> <name>Fred Anderson</name> <associate associate_id="1"> </staff> <staff staff_id="unique_id_here" alpha_key="A"> <name>Jane Anderson</name> <associate associate_id="2"> </staff> <staff staff_id="unique_id_here" alpha_key="B"> <name>Sue Bates</name> <associate associate_id="0"> </staff> <staff staff_id="unique_id_here" alpha_key="B"> <name>John Boxer</name> <associate associate_id="0"> </staff> .... </people> It's imported into my document and indexed thusly <xsl:variable name="staff" select="document($ref_staff)/people"/> <xsl:key name="alpha" match="@alpha_key" use="."/> When I display them in the form I want to separate them out with preference to a certain associate. In this case, lets say associate_id=1. In the using the "native" xml I've got a template that looks like this: <xsl:template match="people"> <xsl:variable name="center_staff" select="$staff/staff[associate/@associate_id = $associate_id]"/> <xsl:variable name="other_staff" select="$staff/staff[associate/@associate_id != $associate_id]"/> <xsl:if test="count($center_staff) > 0"> <fieldset class="span-18 last col-wrap"> <legend class="quiet"> <xsl:value-of select="ancestor::project/associates/associate/title"/> People</legend> <xsl:call-template name="layout_3column"> <xsl:with-param name="objects" select="$center_staff"/> </xsl:call-template> </fieldset> </xsl:if> <xsl:if test="count($other_staff) > 0"> <fieldset class="span-18 last col-wrap"> <legend class="quiet">All other U of M People</legend> <div id="tabs"> <ul> <xsl:for-each select="$other_staff/@alpha_key[generate-id()=generate-id(key('alpha', .))]"> <xsl:call-template name="tab_link"> <xsl:with-param name="alpha_string" select="."/> </xsl:call-template> </xsl:for-each> </ul> <xsl:for-each select="$other_staff/@alpha_key[generate-id()=generate-id(key('alpha', .))]"> <xsl:call-template name="tab_data"> <xsl:with-param name="alpha_string" select="."/> <xsl:with-param name="objects" select="$other_staff[@alpha_key = current()]"/> </xsl:call-template> </xsl:for-each> </div> </fieldset> </xsl:if> </xsl:template> The problem that I have is that because Fred Anderson is not in the $other_staff node set, the As don't show up at all because the keys don't match. I debugged this by running the following two snippets: <xsl:for-each select="$staff/staff/@alpha_key"> <xsl:value-of select="."/> - <xsl:value-of select="generate-id(.)"/> - <xsl:value-of select="generate-id(key('alpha', .))"/> <br/> </xsl:for-each> <xsl:for-each select="$other_staff/@alpha_key"> <xsl:value-of select="."/> - <xsl:value-of select="generate-id(.)"/> - <xsl:value-of select="generate-id(key('alpha', .))"/> <br/> </xsl:for-each>
$other_staff/@alpha_key A - id51618367 - id51618272 A - id51620641 - id51618272 A - id51620731 - id51618272 A - id51620821 - id51618272 None of the keys match for the letter A in the second set because the one that has been keyed is not a member of the set anymore so it's not displayed. If I change the stylesheet to this it works: <xsl:template match="people"> <xsl:variable name="center_staff" select="$staff/staff[associate/@associate_id = $associate_id and associate/@associate_id != 0]"/> <xsl:variable name="other_staff" select="$staff/staff[associate/@associate_id != $associate_id or associate/@associate_id = 0]"/> <xsl:if test="count($center_staff) > 0"> <fieldset class="span-18 last col-wrap"> <legend class="quiet"> <xsl:value-of select="ancestor::project/associates/associate/title"/> People</legend> <xsl:call-template name="layout_3column"> <xsl:with-param name="objects" select="$center_staff"/> </xsl:call-template> </fieldset> </xsl:if> <xsl:if test="count($other_staff) > 0"> <fieldset class="span-18 last col-wrap"> <legend class="quiet">All other U of M People</legend> <div id="tabs"> <ul> <xsl:for-each changed --> select="$staff/staff/@alpha_key[generate-id()=generate-id(key('alpha', .))]"> added --> <xsl:if test="count($other_staff[@alpha_key = current()]) > 0"> <xsl:call-template name="tab_link"> <xsl:with-param name="alpha_string" select="."/> </xsl:call-template> </xsl:if> </xsl:for-each> </ul> <xsl:for-each changed --> select="$staff/staff/@alpha_key[generate-id()=generate-id(key('alpha', .))]"> added --> <xsl:if test="count($other_staff[@alpha_key = current()]) > 0"> <xsl:call-template name="tab_data"> <xsl:with-param name="alpha_string" select="."/> <xsl:with-param name="objects" select="$other_staff[@alpha_key = current()]"/> </xsl:call-template> </xsl:if> </xsl:for-each> </div> </fieldset> </xsl:if> </xsl:template> Is there a better way to do this?
