bookmarklets are javascript links that you put in your favorites and they link you somewhere but with some functionality. see bookmarklets.com for examples. i found a bookmarklet that takes a word you have highlighted and lets you search google for the word.

i recently downloaded a free nifty xml tool called cooktop. of course there are many tools for xml editing

as a note to myself xsl consists of three parts: xslt, xpath, and xml formatting objects. w3schools.com is a site with simple xml tutorials.
