 Use the GeoServer admin interface to edit and modify your SLD file as it will color code your markup and you can submit and apply the modified version in the interface. You can then examine the results by going to and EWX window (http://chg2.geog.ucsb.edu:8080/EWX/index.html) and opening the dataset.
