Re: [jelly] j:include and j:import semantics ? (was: xslt transform fun (newbie))

[Paul Libbrecht]

There definitely seems to be a bug...
Can someone here remember what are the tags import and include exactly 
meant at and, their difference ? The javadoc (hence jellydoc) seems 
definitely wrong.

Having non-jelly-namespaced xml, inside a jelly element or not, should 
output directly to XMLOutput. It seems, however, that j:include and 
j:import both encounter exceptions though different.

Hi Paul,
I tried this
<x:transform xslt="xxxx">
        <j:include uri=""/>
    </x:transform>
but I get a
"<x:transform> javax.xml.transform.TransformerException:
java.lang.NullPointerException"
Humm any ideas ?
We have a ton of xslt stylesheets that we want to reuse with Jelly 
without
making too many changes.

you write
If you are processing a file anyways, why not directly use ant's style
tag ?
Could  you enlighten me on the Ant style tag. I have had a look at
http://jakarta.apache.org/commons/jelly/libs/ant/tags.html but the is 
no
description of the xslt style tag.

Now when we are at it - how do I access a Map key/value pair in Jelly.
 <j:forEach var="set" items="${params}">
             ${set}
         </j:forEach>
I get a "key=value" String in ${set} how do I access the ${set}.key
${set}.value individually ?
I am running commons-jelly-1.0-beta-4.jar and 
commons-jelly-tags-xml-1.0.jar

Many thanks Paul,

1. In the jelly docs
(http://jakarta.apache.org/commons/jelly/pipeline.html)
It describe following way to use the x:transform tag.
<x:transform xslt="file:///test/default.xslt">
        <x:parse xml="file:///test/data.xml"/>
</x:transform>
But it does not work. I get a "x:parser missing var attrib".
I found a workaround.
<x:parse xml="file:///test/data.xml" var="doc"/>
<x:transform xslt="file:///test/default.xslt" xml="${doc}"/>
but it defeats the XML pipeline idea.  I would appreciate if someone
could
comment on the problem.
Have you tried the following ?
<x:transform xslt="xxxx">
        <j:include uri=""/>
   </x:transform>
In all cases, be careful that loading the document in ram is, sadly,
always done in XSLT processors. The XSLT language should have allowed
implementors to provide:
- minimal load in ram
- and delta processing
None are realized, as far as I know.
If you are processing a file anyways, why not directly use ant's style
tag ?
I think x:transform is very useful if you do previous operations on 
the
xml document (or produce it as the result of something else).
There's not much of jelly to modify a loaded document but the whole
dom4j is there for you! (using jexl method calls)
