Developer for help in developing a website


I am developing a WordPress site. My experience with WordPress, HTML and CSS is somewhat limited since I am relatively new. However, I can develop many components of the site but there is one important component where I need WordPress to import an XML file that contains more than 200 chemotherapy treatment regimens, and act like a database that allows user (admin) to search, append, edit and delete records after query. In addition, we will need to create another page where it will only list records and display and print a record when selected by the (user client).I know there are multiple XML importer plugins but I don’t know how to write a Javascript or a code to allow query, and edit the records.
I would appreciate if you can help me out.
