Another newbie question that I could not
find an answer for in the archives.
Part of my web site needs to generate
dynamic content based on database queries. I intend to write my
own logicsheets to get that functionality (I am not using ESQL because I
need to talk to my java model, not directly to the database ).
I used Bonebreaker application as the
learning tool so far; my web page is divvied up into a few sections in terms
of layout:
Menu at the top
Toolbar on the left side
Content on the prime real
estate
So far, this works
fine.
Now, to provide the dynamic
content, I put in a call to a custom tag in the featuredArticle.xml file, like
so:
<singertags:get-name/>
The tag <singertags:get-name/> takes no parameters; it is just
supposed to print "Elvis Presley".
I registered the tag file in
cocoon.xconf. It seems to be loading fine (from what I see in
core.log)
The trouble is: I don't know how
to make cocoon actually process the tag. This has something to do with
Sitemap, but I don't know what I should put in there. What I have now is
this:
Sitemap:
-
<map:match pattern="xsp/**">
-
<map:generate type="serverpages" src="{1}{requestQuery}"/>
-
<map:transform type="cinclude"/>
-
<map:serialize/>
-
</map:match>
-
-
<map:match pattern="*/*.**">
-
<map:act type="request">
-
<map:parameter name="parameters" value="true"/>
-
<map:generate type="request" src="control/{../1}/{../2}.xml{requestQuery}"/>
-
<map:transform type="xslt"
src="view/xsl/{../3}/content.xsl">
-
<map:parameter name="use-request-parameters" value="true"/>
-
<map:parameter name="tab"
value="{../1}"/>
-
<map:parameter name="topic"
value="{topic}"/>
-
<map:parameter name="subtopic" value="{../2}"/>
-
<map:parameter name="tabs"
value="../../../control/config/tabs.xml"/>
-
<map:parameter name="topics" value="../../../control/config/{../1}.xml"/>
-
<map:parameter name="base-url" value="/cocoon/gvs"/>
-
</map:transform>
-
<map:transform type="xslt"
src="view/xsl/{../3}/menupage.xsl">
-
<map:parameter name="use-request-parameters" value="true"/>
-
<map:parameter name="tab"
value="{../1}"/>
-
<map:parameter name="topic"
value="{topic}"/>
-
<map:parameter name="subtopic" value="{../2}"/>
-
<map:parameter name="request-url" value="../../../{show}.xml"/>
-
<map:parameter name="tabs"
value="../../../control/config/tabs.xml"/>
-
<map:parameter name="topics" value="../../../control/config/{../1}.xml"/>
-
<map:parameter name="css-stylesheet" value="default.css"/>
-
<map:parameter name="base-url" value="/cocoon/gvs"/>
-
</map:transform>
-
<map:serialize/>
-
</map:act>
-
</map:match>
Tag in the
Logicsheet:
- <xsl:template match="singertags:get-name">
<xsp:expr>
- Elvis Presley
</xsp:expr>
- </
xsl:template>
FeaturedArticle.xml:
- <
xsp:page
xmlns:xsp="http://apache.org/xsp" xmlns:singertags="http://gvs/singertags">
<page>
Singer Name: <singertags:get-name/>
</page>
</xsp:page>
Menupage.xsl:
<!-- The following line prints non-tag
stuff if <xsp:page> tags are removed from featuredArticle.xml
-->
<xsl:copy-of select="document($request-url)/page"/>
<!-- Does not work regardless:
just sends this out in toto to the browser (which will ignore
it) -->
<cinclude:include src="xsp/{$request-url}"/>
<xsl:apply-templates
select="./article"/>
The Problem:
Instead of printing "Singer Name: Elvis
Presley", it just prints nothing. If I take out the <xsp:page> tags from
featuredArticle.xml, it prints "Singer Name:" and leaves a blank in place of
the tag. Obviously I am doing something wrong (or not doing something) and
this must be a fairly dumb question...
I would appreciate if someone can point me
in the right direction... (I try to compensate for my lack of originality with
copying skills ;))
