Title: Re: xsp:attribute generating a new element instead of an attribute in an already existing element
|
In my last e-mail I've used a diferent XML tree sample than the one I
initially posted here.
I wan't to generate a XML tree like this :
> >
>>expected XML :
>
> >>=========
>
> >><dates
current="30-12-2002">
>
> >>
<date_sel>27-12-2002</date_sel>
>
> >>
<date_sel>24-12-2002</date_sel>
>
> >></dates>
so <dates> must be placed outside the while loop.
The code in my previous mail works, I just don't think that the extra
</xsp:logic><xsp:logic> after <xsp:attribute> is an API
limitation !;)

Yeah it probably would help if I paid attention to what I was
typing,
how about this instead?
<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>
