Subject: [xsl] Joining xml documents on the fly
Ok, I'm in totally over my head here. I'm hoping someone can
help me out.
I've got 2 external (reference) documents I'm including into
my stylesheet.
One is a list of staff. It looks like this (edited for brevity):
<people>
<staff staff_id="123456789" alpha_key="A" sort_key="AberyBrian">
<display_name>Brian H Abery</display_name>
</staff>
<staff staff_id="987654321" alpha_key="A" sort_key="AlbusDeb">
<display_name>Deb Albus</display_name>
</staff>
<staff staff_id="456321789" alpha_key="A" sort_key="AltmanJason">
<display_name>Jason R Altman</display_name>
</staff>
</people>
And the other is the three way join between staff, projects
and roles <project_staff_roles>
<project_staff_role project_id="1" staff_id="123456789"
role_id="staff">
<staff staff_id="123456789" alpha_key="A"
sort_key="AberyBrian">
<display_name>Brian H Abery</display_name>
</staff>
</project_staff_role>
<project_staff_role project_id="1" staff_id="123456789"
role_id="director">
<staff staff_id="123456789" alpha_key="A"
sort_key="AberyBrian">
<display_name>Brian H Abery</display_name>
</staff>
</project_staff_role>
<project_staff_role project_id="2" staff_id="987654321"
role_id="staff">
<staff staff_id="987654321" alpha_key="A" sort_key="AlbusDeb">
<display_name>Deb Albus</display_name>
</staff>
</project_staff_role>
</project_staff_roles>
I want to break this into two groups based on the current project_id.
So if I'm viewing project_id=1
I want two groups of people
Project Staff:
<people>
<staff staff_id="123456789" alpha_key="A" sort_key="AberyBrian">
<display_name>Brian H Abery</display_name>
</staff>
</people>
Non-Project-Staff
<people>
<staff staff_id="987654321" alpha_key="A" sort_key="AlbusDeb">
<display_name>Deb Albus</display_name>
</staff>
<staff staff_id="456321789" alpha_key="A" sort_key="AltmanJason">
<display_name>Jason R Altman</display_name>
</staff>
</people>
I've got the following variables in my document:
<xsl:variable name="staff" select="document($ref_staff)/people"/>
<xsl:variable name="staff_roles"
select="document($ref_project_staff_role)/project_staff_roles/
project_staff_role[(_at_)role_id='staff']"/>
<xsl:variable name="project_staff"
select="$staff_roles[(_at_)project_id=$[project_id]/staff"/>
<xsl:variable name="non_project_staff" select="?????"/>
How do I even go about thinking about this? I've tried
googling it but I have no idea what to search on. I've tried
various iterations of keys, etc but I just can't get it.
The final xslt that gives the desired output is:
<xsl:if test="count($project_staff) > 0">
<fieldset class="span-18 last col-wrap">
<legend class="quiet">
<xsl:value-of
select="ancestor::project/associates/associate/title"/>
People</legend>
<xsl:call-template name="layout_3column">
<xsl:with-param name="objects"
select="$project_staff"/>
</xsl:call-template>
</fieldset>
</xsl:if>
<xsl:if test="count($non_project_staff) > 0">
<fieldset class="span-18 last col-wrap">
<legend class="quiet">All Other People</legend>
<div id="tabs">
<ul>
<xsl:for-each
select="$staff/staff/@alpha_key[generate-id()=generate-id(key('alpha',
.))]">
<xsl:if
test="count($non_project_staff[(_at_)alpha_key = current()]) > 0">
<xsl:call-template name="tab_link">
<xsl:with-param
name="alpha_string"
select="."/>
</xsl:call-template>
</xsl:if>
</xsl:for-each>
</ul>
<xsl:for-each
select="$staff/staff/@alpha_key[generate-id()=generate-id(key('alpha',
.))]">
<xsl:if
test="count($non_project_staff[(_at_)alpha_key = current()]) > 0">
<xsl:call-template name="tab_data">
<xsl:with-param name="alpha_string"
select="."/>
<xsl:with-param name="objects"
select="$non_project_staff[(_at_)alpha_key = current()]"/>
</xsl:call-template>
</xsl:if>
</xsl:for-each>
</div>
</fieldset>
</xsl:if>
I hope this is clear. Any help would be much appreciated.
Thanks in advance.
Joelle
