Search Using XML File?

When attempting to collaborate with other employees, it is necessary to contact them. CompanyX needs a tool that allows an employee to quickly get another employee�s contact information and general business context that employee works in. The tool should allow searching (including partial matches) by employee name or employee id. If multiple employees are returned by a search, a list of the employees matching the search criteria should be displayed with the following data for each employee: first name, last name, employee id, division (one division has many employees), organization (one organization has multiple divisions), and job title. If only one employee matches the search criteria (or if one employee is selected in the list described above), the tool should display full data. Full data for an employee consists of first name, last name, employee id, nickname, division, organization, job title, phone number, cell phone number, pager, USPS address, fax number, internal mail address.
