backup howto livejournal blog 2007 May 22, 3:22I've created an
update to the IE7 feed display.
After working on my
update to the XML source view I tried running my resourcelist program on other IE DLLs including ieframe. I found that
one of the resources in ieframe is the XSLT used to turn an
RSS feed into the IE7 feed display.
My first thought for this was that I could embed enclosures into the feed display. For instance, have controls for youtube.com videos or podcast audio files directly in the feed display. However, I
found that I can't use object or embed tags that rely on ActiveX controls in the page or in frames in the feed display.
With that through I decided I could at least add support for some RSS extensions. Thanks to
IE7's RSS platform which provides a
normalized view of RSS feeds it was really easy to do this. I went to several popular RSS feeds and RSS feeds that I like and took a look at the source to see what extensions I might want to add
support for.
For
digg.com I added support for
their RSS extension which includes digg count, and submitter name and icon. I
added the digg count in a box on the right and tried to make it fit in stylistically. For the
iTunes RSS extension
I add the feed icon, feed author, and descriptions. I was surprised by how much of the podcasts content was missing from the feed view. I also added support for a few other misc things: the
slash RSS extension's section and department, the feed description to the top of the feed display, and the atom author icon.
I wonder what other goodies lurk in IE's resources...
feed res slashdot digg resource itunes technical browser ie rss extension 2007 May 17, 5:16Previously I created some
resource tools and then I used them to
overwrite msxml3's
XML source view. In this update I've added support for the XPointer Framework.
This time around I've started to add support for the
XPointer Framework to my
XML source view and
I've added
installation instructions. The framework consists of a series of pointer segments each of which has a scheme name followed
by data in parenthesis. For example 'scheme1(data1)scheme2(data2)scheme3(data3)'. A pointer segment resolves to a portion of the XML document based on the data and the scheme name. The whole pointer
resolves to the first segment that successfully resolves. That is, from the example, if scheme1 resolves to nothing and scheme2 resolves to something then that's used and scheme3 is ignored. In
addition to the framework I've added support for the
xmlns scheme which binds namespace prefixes to a namespace URI and the
element scheme which is a simple way to resolve to particular elements in an XML. I also have limited support for the
xpointer scheme the content of which is resolved as an
XPath with some extra functions (which I don't support --
hence the limited). I've also thrown in schemes for the two
SelectionLanguage values supported by msxml3.
Next time I might try to support the xpointer functions that aren't in xpath using
msxml script. But I think I'm losing steam on
this project... we'll see.
resource technical xml xpointer res xpath xslt 2007 May 11, 8:55Last time, I had written some resource tools to allow me to view and modify Windows module resources in my ultimate and noble quest to
implement the XML content-type fragment in IE7. Using the resource tools I found that MSXML3.DLL isn't signed and that I can replace the XSLT embedded resource with my own, which is great news and
means I could continue in my endevour. In the following I discuss how I came up with this
replacement for IE7's XML source view.
At first I thought I could just modify the existing XSLT but it turns out that it isn't exactly an
XSLT, rather its an
IE5 XSL. I tried using the
XSL to XSLT converter linked to on MSDN, however the resulting document still
requires manual modification. But I didn't want to muck about in their weird language and I figured I could write my own XSLT faster than I could figure out how theirs worked.
I began work on the new XSLT and found it relatively easy to produce. First I got indenting working with all the XML nodes represented appropriately and different CSS classes attached to them to make
it easy to do syntax highlighting. Next I added in some javascript to allow for closing and opening of elements. At this point my XSLT had the same features as the original XSL.
Next was the XML mimetype fragment which uses
XPointer, a framework around various different schemes for naming parts of an XML document. I focused on the
XPointer scheme which is an extended version of
XPath. So I named my first task as getting XPaths working.
Thankfully javascript running in the HTML document produced by running my XSLT on an XML document has access to the original XML document object via the
document.XMLDocument property. From this this I can execute XPaths, however there's no builtin way to map from the XML nodes selected by
the XPath to the HTML elements that I produced to represent them. So I created a recursive javascript function and XSLT named-template that both produce the same unique strings based on an XML node's
position in the document. For instance 'a3-e2-e' is the name produced for the 3rd attribute of the second element of the root element of the XML document. When producing the HTML for an XML node, I
add an 'id' attribute to the HTML with the unique string of the XML node. Then in javascript when I execute an XPath I can discover the unique string of each node in the selected set and map each of
them to their corresponding positions in the HTML.
With the hard part out of the way I changed the onload to get the fragment of the URI of the current document, interpret it as an XPath and highlight and navigate to the selected nodes. I also added
an interactive floating bar from which you can enter your own XPaths and do the same. On a related note, I found that when accessing XML files via the file URI scheme the fragment is stripped off and
not available to the javascript.
The next steps are of course to actually implement XPointer framework parsing as well as the limited number of schemes that the XPointer framework specifies.

After
Carissa and Elijah's wedding Sarah and I went to San Francisco. We drove in, well Sarah drove anyway, still in
the PT Cruiser Sunday morning and checked into our hotel,
Hotel Diva. I was originally concerned that I wouldn't fit in as I don't really consider myself a
diva, however the hotel was cool. They have Internet rooms setup in various themes, the front desk is always staffed, our room had a very modern look, and when we entered the flat-screen over the
front desk was playing an episode of Aqua Teen Hunger Force.
We walked around a bit before going to the
SF Museum of Modern Art. There was a Picasso exhibit at the time
which we could see for only $3 more. It felt kind of wrong like my ticket was super-sized. I think the most memorable piece I saw was
three white
panels which consisted of three blank panels. Art. Sure. After that Sarah wanted to see the giant Hello Kitty store she had heard of from her sister. We ended up going to the Westfield Shopping
center which has a disappointingly average sized Hello Kitty store. Apparently the giant one is gone. That night we went to
First Crush for dinner. I had a
flight of wine which consists of three one-third sized glasses of various but complimentary wines. It was a great restaurant in terms of food, drink, atmosphere and service.
The next morning we were even more the tourists when we went down to Fisherman's Wharf and Pier 39. We visited the famous wax museum and purchased multiple
pounds of taffy. On the way back to the Oakland airport we got to experience a little traffic as part of
the
580 freeway had collapsed the morning we arrived and was still under repair on our way out. We survived of course and I think the trip went rather well.
sanfrancisco personal california sfmoma nontechnical 2007 Jan 19, 9:15I've moved my homepage to server-side scripting. Previously I've mentioned that
I was using client side scripting to interpret and sort my
livejournal and delicious entries together. Now I'm using
PHP and
XSLTs to process and sort my livejournal,
delicious, flickr, and librarything entries. See
my homepage for the finished result.
LibraryThing is pretty cool despite being pretty niche. Its like flickr but for books. I display a random sampling of the covers of books I have listed in
librarything on my page. I've also hooked the display of the covers of my book up to the corner image. Now when you hover over the cover of a book a bigger picture of its cover appears in the corner
of the webpage. Also, flickr entries in the main section how have the same on hover behavior.
This may not be the best use of my time, but its still fun.

that point I can do fun stuff like sorting them into lists on my page. Neat. This is how I spend my free time... OK.
xml badgerfish feed rss script livejournal delicious homepage 2004 Apr 22, 3:52I actually have something to say which I thought would be appropriate for the LiveJournal format. Why I haven't posted to the LiveJournal for such a great length of time can be saved for later. I
spent Easter weekend and the Monday following, in Washington, the state. Microsoft paid for me to fly up and stay in Washington so I could do the technical portion of the interview with them. I hung
out with my friend Jeannie and she showed me all around Seattle on Saturday and Sunday. Each night we had somewhat expensive dinners, all paid for by Microsoft. It was cool. On Sunday I stayed at a
nice hotel in Redmond and the next morning I spent just short of eight hours being interviewed by five different people from different groups within Microsoft. Each sub interview consisted of two
portions. First there was the general portion where they would ask me why I wanted to work there, ask about my previous experience, and those sort of non technical questions. The second portion would
take the majority of the time and it would be me trying to solve some technical problem they'd present. By the end of the interview my hands were gray with dry erase marker ink because apparently
everybody's got a whiteboard and they all want me to write code on them. I have to go to class soon and I might post some more stories related to this trip, but mostly I wanted to say that last week
I received a great offer from them and I'll probably be moving up to Washington sometime (weeks or months?) after graduation. Also, I've changed my AIM name from SequelGuy to SequelDave. My email
address will also have to change soon, but I don't know to what it will change.
2003 Feb 12, 1:35After much insisting and assisting from Jessica, I have a Live Journal account. Hopefully in the near future I'll be able to make it look respectable and add in more friends. Thanks for the code and
suggestions Jessica. This morning, I ran around collecting various forms from a plethora of offices in an attempt to figure out how to graduate. I had a modicum of success and I'm fairly happy, but
all this thinking about the future has left me feeling tired and little time to study for Chemistry, or, as I refer to it, the class I hope I don't have to take next quarter. Speaking of which, I
really should get back to that. Or maybe I'll just go to sleep.
