NullPointerException in xalan parser package

[Guillaume Jeudy]

Hi,

I'm trying to serialize a DOM constructed from the following URL which
is subject to change very frequently:

http://www.bbc.co.uk/syndication/feeds/news/ukfs_news/world/asia-pacific/rss091.xml

I sometimes receive this error:

java.lang.NullP ointerException :

at DynamicPortalSe archProcessor.p rocessSearchSit e(DynamicPortal SearchProcessor .java,

I suspect this is because the XML source is in ISO-8859-1 encoding and
the xalan serializer that i'm using does not support this encoding
it's trying to use UTF8 encoding... Can anyone help? I'm using the
xalan version "j2_2_D11"
