Null values

[Esteban Gonzalez]

I´m getting this error...
    java.lang.IllegalArgumentException: The input node can not be null for a
DOMSource for newTemplates!

It´s probably because the xml has tags like this
<seguroEmitido>
                        <pais></pais>
                        <codigo></codigo>
                        <nroVoucher></nroVoucher>
                        <nro_certificado></nro_certificado>
                        <cod_cia_seguros></cod_cia_seguros>
                        <nro_recibo></nro_recibo>
                        <fec_recibo></fec_recibo>
                </seguroEmitido>

The thing is... what should i do?... erase those nodes?..
set a blank space to it?

if i erase the nodes in the xml.. will the xsl still work if those nodes are
missing?

Best Regards,
