[Dojo-interest] XML parsing problem

[umeshawasthi]

hi Jim

i agree with you.initially we have made this utility in java and we are
getting our xml from server and sending back this xml to server using
servlet and apache web server.
                 but the real problem is that we don't have any control over
the design process client want every processing at client side using DOJO.We 
have to parse our XML received from the server at client side and even the
data from the form has to be converted in to XML at client side only,but the
data  base intraction is  to be done by JAVA, for that client has written
there own class files.Please suggest me to get out from this problem as i
don't have any kind of resources and any such idea.We are really very new to
DOJO

Thanks,
Umesh
