[jelly-xml] xml:copy outputs attributes as text also
hi-
im trying to transform some documents with jelly:jsl in order to modify
the attributes of a specific element ('item'), the rest of the document
remaining unchanged. so i have something like that in my jsl file :
<jsl:template match="/" trim="false">
<jsl:applyTemplates select="project"/>
</jsl:template>
<jsl:template select="item">
<!-- do stuff. works correctly -->
</jsl:template>
<jsl:template select="*">
<!-- if currentNode.name == 'item', apply item template, else do
this : -->
<x:copy select=".">
<jsl:applyTemplates />
</x:copy>
</jsl:template>
the problem i face is that for elements different than 'item',
attributes are outputed as text as shown below :
<menu name="menu_1">menu_1 <<===== here's the error
<item name="item 1" href="/item_1_link"> <<=== no error for item
transformation
</menu>
i guess the problem comes from my xsl tranformation, more particulary
from my use of x:copy. although i cannot see what the error is. what am
i missing ?
thanks for your help.

Paul,
thank you very much for your help. i think it really helped by giving me
ideas on how to fix the problem i was encountering. i was using jexl and
xpath. i explain here how i solved the problem in case someone is
interested.
i had smtg like [1] in jsl file. i used <jsl:applyTemplates select="* |
text()"/> to ensure that attribute values were not output as text (my
first post in this thread), and the first template was defined to make
sure that text nodes were rendered (otherwise they didnt appear).
however that didnt do it since text children were outputted after all
other children. i solved that by just defining another empty template :
<jsl:template match="@"/> and replacing the <jsl:applyTemplates
select="* | text()"/> isntruction by this one <jsl:applyTemplates />.
this "solution" seems to work, however im not really satisfied with it,
because it seems a bit weak. but, well, that will do it for now. thanks
again.
[1]
--------- previous bogus templates -------------
<jsl:template match="text()">
<x:set var="p" select="."/>
${p.get(0).getText()}
</jsl:template>
<jsl:template match="*">
<x:copy>
<jsl:applyTemplates select="* | text()"/>
</x:copy>
</jsl:template>

Gilles,
Is there any reason you don't use something like the following ??
<x:forEach select="$doc/img/@href" var="hrefAtt">
${hrefAtt.setValue('myNewValue')}
</x:forEach>
I've been pretty much more successful using a mix of jexl-method-calls
and xpath than plain-xpath with the XML-taglib. The only issue is the
type of the result of an XPath expression which can be very diverse...
(oh, and you might be bitten by the HTML output btw... the solution is
dom4j-1.4 or to fix 1.4-b8).

Paul,
thanks for your reply. indeed im using it from within maven to transform
some xdoc-processed document (using also jelly:html - need to change the
href attribute of img elements). Ive logged in a non-systematic some of
the outputted elements, i will do it more systematically because in fact
the template i posted yesterday ("* | text()") doesnot work : all text
children of a given node are outputted *after* all other children..
however it is perhaps my xsl knowledge that is a bit light ;) so ill
continue to investigate and come back with the solution if i ever find
it ;)
regards,

Gilles,
There's a fair amount of possible variables that can bite you here.
Are you using jelly within maven ? If yes, this might be infamous
output bugs of dom4j 1.4b8 which is used in maven (as the release broke
with entities).
I would do something like logging the elements of your process (using
the log taglib)... the dom4j' default-nodes toStrings are pretty
impressing!
(and also expensive I think).

i "solved" this problem by adding a template on text nodes and doing
this
<x:copy select=".">
<jsl:applyTemplates select="* | text()/>
</x:copy>
in the template select="*".
my jsl transfo is not very elegant but still works..
