Hopefully one of the forum administrators will have pity on me and change the 'dada' typo !!
I'm not sure myself what information is going to be used from the XML file, I have a hunch it will be required to take only some of the data from the XML file.
Existing PHP backend has standard DB management i.e. fill in form fields click submit and data is edited/added to MySQL DB, now several new columns need to be added to MySQL DB the information for these additional columns is contained in existing XML files (these XML files do contain additional data which isn't required too).
So target is to add an import button to the existing backend that will parse the XML and strip out only the information required and drop it in to the corresponding columns in MySQL DB.
I've no idea pretty much about XML to be truthful so if I speaking in the wrong language and confusing the issue, I'll apologise now !!
