I assume there may be multiple xml files you need to parse? What you need is a series of nested loops. The first one loops through the list of xml filenames you need to parse (you can get this list from a directory listing if you need), the second goes through each <directive> tag, the third through the <rule> tags. The attributes of each tag can be pulled out quite easily. Are these a list of known attributes, or unknown? If you know what they are, you can hard-code retrieving their values, but if not, another loop will be able to fetch these out for you. Thanks, Ash http://www.ashleysheridan.co.uk
