Regular Expression Help

I need some real fast help with 1-2 regular expressions. The first, you have the pattern &bold;Some Bold Text&endbold; &italic;SomeItalicText&enditalic; I can't use the <tag>format in this case or else I would. So need an expression that basically parses these sections into different match groups for type: (bold, italic - between the & and the ;) text to apply: the text gbetween the bold and end bold. Open to suggestions. Need this quick is someone wants to make a few bux tonight. **Included extra description based on comments on bidders, hopefully this clears it up a bit more. ** Basically what happens in the parser is this. We find all the matches that are configured i.e &bold;This Text&endbold; Where I need to extract the text between the matching tags (which will always be as &tag;The text to extract&endtag; Based on the tag type, we load a particular template. That template is essentially an xml file loaded into memory. We need to take the extracted text and place it at a point in this loaded file (String) utilizing .NET string formatting ({0}).
