Your solution only works when the "if" is true for the first loop
iteraction. After that new child elements have been created and the attribute
won't be placed where I want to.
A working solution is -- don't try to understand the source code, just look
at the generated XML (grab your underware) :
<dates>
<xsp:logic>
ResultSet rsDates = <esql:get-resultset/>;
while(rsDates.next())
{
if (rsDates.getString(1).equals(today)
{
currentDate =
today;
}
(...)
//
I'm storing the rsDates here in an ArrayList
(...)
}
<xsp:attribute
name="current"><xsp:expr>currentDate</xsp:expr></xsp:attribute>
<!-- GRAB YOUR UNDERWARE
-->
</xsp:logic>
<xsp:logic>
<!-- GRAB YOUR UNDERWARE
-->
iter =
listDates.listIterator();
while(iter.hasNext())
{
<date_sel><xsp:expr>(String)iter.next()</xsp:expr></date_sel>;
}
</xsp:logic>
</dates>
generated XML *without* the
</xsp:logic><xsp:logic> tags between the <!--
GRAB YOUR UNDERWARE --> comments.
===================================================================================
<date_sel current="30-12-2002">30-12-2002</date_sel>
<dates> </dates>
generated XML *with* the
</xsp:logic><xsp:logic> tags between the <!--
GRAB YOUR UNDERWARE --> comments.
===================================================================================
<dates current="30-12-2002">
<date_sel >30-12-2002</date_sel>
</dates>

xsp:attribute generating a new element instead of an attribute in an already

Luís,
I've seen the same things you have but I guess
from a Cocoon
perspective, it's not really an error; although it doesn't
work the way
you want it to. Maybe this would help
you:
<xsp:logic>
while(rsDates.next()) {
<dates>
if
(rsDates.getString(1).equals(today)
{
currentDate
= today;
<xsp:attribute
name="current"><xsp:expr>currentDate</xsp:expr></xsp:attribute>
}
<date_sel><xsp:expr>rsDates.getString(1)</xsp:expr></date_sel>
</dates>
}
</xsp:logic>
