Each result set is saved in a single .xml file (called results.xml). This .xml file stores information on each of the test result nodes in the display. The information in these nodes is used to dynamically create .htm files that are shown in the top-right pane of the Test Results window.
Each node in the run results tree is an element in the results.xml file. In addition, there are different elements that represent different types of information displayed in the test results. You can take test result information from the .xml file and use XSL to display the information you require in a customized format (either when printing from within the Test Results window, when displaying test results in your own customized results viewer, or when exporting the test results to an HTML file).
XSL provides you with the tools to describe exactly which test result information to display and exactly where and how to display, print or export it. Using a XSL editor, you can modify the .css and .xsl files in the results folder, to change the appearance of the report (fonts, colors, and so forth).
For example, in the results.xml file, one element tag contains the name of an action, and another element tag contains information on the time at which the run was performed. Using XSL, you could tell your customized editor that the action name should be displayed in a specific place on the page and in a bold green font, and that the time information should not be displayed at all.
