PHP + XML simple custom implementation

We do have a small excel file with about 30 data rows, the excel file has about 30 columns, 25 of these colums are pictograms with true or false values. What needs to be done : - Convert this excel file into XML standard - Create a php small application that allows to manage the xml records , by writing direclty to the xml file. (add/edit/record) - The php app must have a login form (hardcoded login and password) - The php app form that allows to manage the data must show the pictograms as in the excel file (checkbox) - No MySQL envolved, just XML
