Re: Pass XML fragment to tile?

[Ruth, Brice]

I think we're in business. SWEET!! Thanks.

Ah, well, here's where I'm out of my element. Perhaps (in the tile):

<tiles:importAttribute name="contextNode"/>
<x:forEach select="$contextNode/family">

no, is this what I should be doing? Do I have to do anything special in 
my tile to bring "contextNode" into scope? I've been using

<c:set var="varName"><tiles:getAsString name="varName"/></c:set>

for all the other parameters I pass into the tile ...

Are you doing something like:

<x:forEach var="node" select="$xml//catalog">
<tiles:insert ...>
  <tiles:put beanName="node" name="contextNode"/>
</tiles:insert>
</x:forEach>
And then in your tile using "contextNode":

<x:forEach select="$contextNode/family">

I'm not having a problem using the proper attributes within the foreach, 
I'm having a problem passing an XML fragment to my Tile. I need to be 
able to pass

<family order="1">key1</family>
<family order="2">key2</family>
...
to the Tile - and that's not happening, as far as I can tell. Within the 
foreach I'm doing a few different things, pulling out nameKey, and 
various other attributes and such - and that's all fine, its actually 
getting the entire node that is the "current" node and passing that to 
the Tile that seems to be troublesome.

So, my XML for a particular category looks like this:

          <category order="8" nameKey="nav.crafts.webcat.trimmers">
              <family order="1">nav.crafts.prdctfm.prsnlppr</family>
              <family order="2">nav.crafts.prdctfm.rtry</family>
          </category>
So, with my x:forEach XPath statement, the "context" node is a category 
like this - and I can pull out @nameKey, @order, etc. - to my heart's 
content. I can also do an x:if on "family" to determine if any family 
nodes exist in the current context - this is all OK.

However, there's processing that the tile I include in my x:forEach 
needs to do that needs this XML fragment (specifically, it needs to loop 
through each family and do something specific, much in the same way that 
the parent is looping through each category and doing something 
specific). So, I need to pass XML like that above, from the "current" 
context to the Tile ... somehow.

Is this possible?

That's fine, isn't it? It should just be the string representation of
         

the
   

context node (i.e. nodeclass.toString()). What if you do:

<x:forEach select="$xml//catalog">
nameKey: <x:out select="@nameKey"/>
</x:forEach>

Hrmpf, not working they way I expected.

When I add var="node" to my x:forEach, and then use <c:out 
value="${node}"/> to display the contents (as this is what would be 
passed to the Tile, via <tiles:put>) - I get the following:

[category: null]

The XPath statement I am using as my select for the forEach, has as its
           

last node, "category" ... what I would hope to get is either something 
like this:

<category order="3" nameKey="nav.section.whatever">
 <family order="1">whatever</family>
 ...
</category>
-OR- just the list of "family" nodes.

I don't know much about Tiles, but <x:forEach> can explicitly export a
   

        

             

scoped
 

      

           

variable via its "var" attribute:

<x:forEach var="node" select="...">

It also implicitly sets the context node each time through an
             

iteration.

I'm
 

      

           

assuming that another XPath expression within the tile would operate
   

        

             

realtive to
 

      

           

the context set by <x:forEach>. If you know Tiles and have some handy
        

             

test
  

       

   

        

             

XML
 

      

           

data, it shouldn't be too hard to test out either (or both) of those
   

        

             

approaches...

I have an x:forEach loop (JSTL) that contains within it a
               

<tiles:insert>
   

          

statement - and I'd like to pass the current node of XML to the tile
               

for
   

          

additional processing (conditionally). Is this possible? Within the 
tile, I'll need to do an x:forEach loop on the passed in fragment, so
               

I
   

          

believe I'll need to be able to use x:parse on the fragment that was 
passed in. I'm open to other ways of doing this, as well, but they
               

need
   

          

to only involve what can be done within a JSP/tile, really. I'm 
extending an existing set of code, and am not really open to rewriting
               

it all :)
