Extract xml to store into db

Hi all,

I need to get the data from the xml file and store it onto the database. Is there anyway of doing this?

thanks

You can do this using SAX or DOM and parse the xml file. You can write Xpath queries to get parts that you require using DOM? I cant quite remember but I have used both methods in the past.

Let me know if you need anymore help.

Cheers

Can u give example...?

Thanks

Ok here is a small example, you will need to pick through the method and get the bits you want out. I have also removed some parts as it is sensitive to my employment role... But it shouldnt be anything of any importance but this method may not compile now, it will probably just be a bracket missing or something. Good luck! ps this is using DOM:

Code:
