Http Auth in a Firefox bookmarklet

Http Auth in a Firefox bookmarklet I'm trying to create a bookmarklet for posting del_icio_us bookmarks to a separate account. I tested it from the command line like: wget -O - --no-check-certificate \ "https_seconduser:thepassword@api_del_icio_us/v1/posts/add?url=http_seet_dk&description=test" This works great. I then wanted to create a bookmarklet in my firefox. I googled and found bits and pieces and ended up with: javascript:void( open('https_seconduser:password@api_del_icio_us/v1/posts/add?url=' +encodeURIComponent(location.href) +'&description='+encodeURIComponent(document.title), 'delicious','toolbar=no,width=500,height=250' ) ); But all that happens is that I get this from del_icio_us: <?xml version="1.0" standalone="yes"?> <result code="access denied" /> <!-- fe04_api_del_ac4_yahoo_net uncompressed/chunked Thu Aug 7 02:...

How can I turn a string of HTML into a DOM object in a FF extension?

How can I turn a string of HTML into a DOM object in a Firefox extension? I'm downloading a web page (tag soup HTML) with XMLHttpRequest and I want to take the output and turn it into a DOM object that I can then run XPATH queries on. How do I convert from a string into DOM object? It appears that the general solution is to create a hidden iframe and throw the contents of the string into that. There has been talk of updating DOMParser to support text/html but as of Firefox 3.0.1 you still get an NS_ERROR_NOT_IMPLEMENTED if you try. Is there any option besides using the hidden iframe trick? And if not, what is the best way to do the iframe trick so that your code works outside the context of any currently open tabs (so that closing tabs won't screw up the code, etc)? This is an example of why I'm looking for a solution other than the iframe hack, if I have to write all that code to have a robust solution, then I'd rather keep looking for something else. 5 Answers ...
