I need nice samples of XPath and CSS expressions for HTML
Something like /html/body/p…
- o'Reilly's XPath an XPointer does not have a lot HTML examples
- search the web for "xpath html" – there are a lot of hita

my MacBook made a funny noise, sounded a little like "dying hard disk"
how bad! I hate that kind of noise. disks aren't really expensive, but will I be able to copy all the contents of the old disk to the new one, before it's really dead? whatever variant, they all cost far too much time.
"… is now following you on Twitter" – why do I hate these notifications?
I hate them, because 99% of these new followers simply expect you to follow them back, and their names just don't sound intriguing, so I will never follow them back.
my new page scraping assignment – getting familiar again with my toolkit
For my new page scraping assignment I thought for a while of trying a much more modern approach.
That actually kept me from really starting it for quite a couple of weeks now, because it seemed so very tedious and I thought, I don't have like 3 shots for it.
This week I thought about going with my own old approach and about making use of the state-of-the-art technology at a (slightly) later stage. That should work.
So where is my software and where is my documentation?
- I remember, I had left a link here at my Aleph-Soft.com website
- that leads me to my slightly more extensive dedicated article
- of course, while I read it, I switch to the sources of that article, so that I can improve the article "en passent"; OMG: running that DocBook website toolchain even works after at least a year or so! I'm amazed. well, not updating software does have some positive side-effects.
- does LiveHTTPHeaders still work with my current Firefox? LiveHTTPHeaders is one of the reasons I still keep my Firefox updated, although I chose Chromium as my main browser on all platforms (*** bookmark ***)
- what about its cousin ieHTTPHeaders for IE? WTF, where does it actually live and get maintained? alright, I assume Jonas Blunck is the creator and maintainer
- is there anything like *HTTPHeaders for Chrome/Chromium? that would be nice; I would have to make my respective tool read its logfile then
- creating a perl script from LiveHTTPHeaders's log file still works
- integrated that perl script into my framework for that kind of stuff
- download the root HTML page, parsing it, extracting the 1st few bits of information wanted
- download the 1st linked page; the navigation doesn't go further / deeper than this
- TBD: extract the information details from that linked page; CAVEAT: there is an optional intermediate ("region") level within that page
- …

at its best, "philo-Semitism" led a narrow part of British society to favor the resettlement of Jews in their homeland

I was tempted to mention, that the link refers to a rather interesting article, but for what other reason did it find its way here?

apparently SPARQL is not going help me with my web-harvesting / page-scraping task
What a pity! Would have been far too elegant. But if everybody makes use of RDF, stealing is just too easy.

Dennis Ritchie's legacy of elegantly useful tools - O'Reilly Radar
Dennis Ritchie's legacy of elegantly useful tools - O'Reilly Radar: "We need more people who share Dennis Ritchie's spirit."
Learning SPARQL - O'Reilly Media / came up another time
Learning SPARQL - O'Reilly Media: "Querying and Updating with SPARQL 1.1"
An update alert came in from O'Reilly.
The hope grows, that SPARQL may be the elegant solution to my current web harvesting / page scraping task.

Update 2011-11-02
- Started reading the book
- installing the software and the samples
- running a few samples
- looks as if SPARQL cannot query HTML resp. XML not formatted resp. marked up specifically (frustration here on my side)
