I'd like to format maths equations using MathML, with LaTeX-like syntax, in my blog posts hosted by Google Blogger; but references, on Google's site and elsewhere, to articles on how to conveniently do this seem non-existent.
The few articles I've found, on MathML generally, presupposes one can control the contents of an entire page, for example putting tokens in the "<html>" tag, which I don't think applies to Google Blogger.
The best site I've found is Ionel Alexandru's code at http://www.fmath.info/ But even there the documentation is very sparse and it isn't obvious how one would use his
scripts/packages for this.
Maybe I'm just being thick. But surely people must be using MathML in Google Blogger, and if so I'd be very interested in references to how it can best be done (preferably via an XML solution rather than dozens of little inline images in the text !)
Failing that, are there standard "register and start blogging" facilities/sites other than Google Blogger that make it easy to use MathML or where it is available as standard?
Cheers

I've written a javascript module, jqmath, to do what you want. See http://mathscribe.com/author/jqmath.html.
Instructions on how to use it in Google Blogger are at http://mathscribetheblog.blogspot.com/2011/03/jqmath-in-blogger.html.
By the way, those instructions do have you edit your <html> tag, which Google Blogger happily let me do. (I just did it to add a MathML namespace prefix for the MathPlayer plugin for Internet Explorer, so actually things would work ok, but less well, without it.)
I hope you like this. If you have any problems, post the link to your blog, and I'll take a look at it.
I use Peter Jipsen;s script, modified a bit, to get mathml into blogger

I have been using Platypus & Reportlab for several weeks using Python, and would caveat this by saying that I am definitely a beginner, and my code isn't "good" code, but ...
I tend to work by looking at an example, testing it, and then adapting it to my needs...
With this approach, I managed to get a table of contents to work.
I also wanted to have a Page x of y working, which again, I found code, and after a lot of hassle, managed to get it to work with my Table of Contents, which I thought I then understood more about the applications, but ...
I had experienced links working - or not working separate to the ToCs.
However, when I merged my samples for ToC and Page x of y, I have a wonderful Toc, with links for each topic I wanted - but, the links all go to the top of the document.
I have looked at other examples I have tried, and find some where links using <a href="#MYANCHOR"... and <a name="MYANCHOR"... have the same issue.
I have also added into my main code, a link using the <a href=... but using one of the link destinations that a ToC would use - and this again jumps to the top of the document.
I put all the elements that form the document into a list called e.g. element so I would have code such as element.append(PageBreak()) and then I can print out all the element list to see what is there, and compare it to examples where it doesn't work, and I can see no significant difference.
If I provide an external link to a website (e.g. that excellent stackoverflow.com) those links work, but internal ones don't - which I accept are handled differently, but I hope it indicates where my failures lie!
I would love to understand why the links are so fickle, as I would like to get links to work in a table, and from a drawing, which to my mind should be possible, ... which may just highlight my ignorance - for which I apologise...
Any help would be really appreciated...
Many thanks,
How could I access a website and turn components of the website into strings. For example taking information from Facebook posts. I have done a little searching but can't find any good tutorials or anything useful.
Try looking at this tutorial. It should get you more familiar on the subject and start you off on the right track.
As it states at the beginning of the tutorial...
How to Parse HTML on iOS
Let’s say you want to find some information inside a web page and
display it in a custom way in your app. This technique is called
“scraping.” Let’s also assume you’ve thought through alternatives to
scraping web pages from inside your app, and are pretty sure that’s
what you want to do. Well then you get to the question – how can you
programmatically dig through the HTML and find the part you’re looking
for, in the most robust way possible? Believe it or not, regular
expressions won’t cut it! Well, in this tutorial you’ll find out how!
You’ll get hands-on experience with parsing HTML into an Objective-C
data model that your apps can use.

I have the following problem: I have a lot of papers in pdf format and I have to extract information from the first page of each one and then save it into a database
I just need to extract, the title, the abstract, keywords, authors list, universities list, emails. I want to do a script to get a string for each one of that fields, for each paper.
How can I do that? Does anyone already did that? What languages and tools do you recommend me?
and Does exist a paper repository that already do that database feeding?
Considering the pdfs could be with different encodings, I have to deal with this problem too. Any help with this would be great.
An example of a paper its here
Greetings!
http://pdfbox.apache.org/
You have to check about the security of the pdf, that it's really text and not an image. Check the command line application of pdfbox if it works extracting the text, then you can use the jar and use http://pdfbox.apache.org/apidocs/org/apache/pdfbox/examples/util/ExtractTextByArea.html
Hope it helps....
By the way it's java...
edit.
I have not used this as a jar library http://www.qoppa.com/pdftext/, but I used the example application and it works, but I decided to go with pdfbox...
You need a API to read your pdf.
Seems fine (I never try it though)
You can probably find others with this link :-)
I want my Rails App to parse external websites for a trackback URL but I'm not really sure if I should just look for a
Text
or follow the RDF specifications described by sixapart. Or both. Wordpress and Techcrunch both only offer a rel="trackback" link and they should know. On the other hand maybe some blog only provides RDF and I'm missing the link.
What do you think?
And is there any ready gem/plugin out there (it's really hard to google for trackback...)
Thanks.
UPDATE
I'm now first trying to find the RDF information. If I do not find anything, I look for the link tag. I was refering to the sixapart specifications. Thanks for your help.
I'm checking for both now (first RDF, then link if not successfull). I was refering to the sixapart specifications. Thanks for your help!
I am unlucky to be in charge of maintaining some old Yahoo! Store built using their RTML-based platform.
Recently I've noticed that HTML code generated by some RTML functions is sprinkled all over with "padding images" (or whatever is the conventional name for those 1x1 pixel images used to enforce layout). I have nothing against using such images, but... all those images are supplied with an ALT attribute like this:
<img href="http://.../image1x1.gif" alt="pad">
With all due respect to the original authors of RTML, but they must have been smoking something when they came up with this "accessibility enhancement"... :-(
Anyway, here are my questions:
Does anybody know a list of all RTML functions that generate HTML with all these "pad" images?
Is there any way to get rid of all those alt="pad" attributes without rewriting a lot of RTML code?
NB: This may sound a little cynical, but improved accessibility is not the main goal here. The main goal is to stop exposing those moronic alt="pad" attributes to Google and other smart search engines. So client-side scripting is not going to help, as far as I know.
Thank you!
P.S. Probably, most of you are really lucky and never heard of RTML. Because if somebody would establish a prize for software products based on
commercial success
------------------
usability
ratio, this RTML-based "platform" would probably win the first place.
P.P.S. Apparently someone from Yahoo! finally listened, because I can no longer find those silly "pad" tags in the RTML generated for our store. Nevertheless, one of the ideas offered in response to my original question does provide a very practical solution - not just to the original problem but to any similar problem with RTML platform. See the winning answer - it's really good.
The only way I see is to have your own website front-end that will filter whatever you want from the RTML site....
for example, your rtml site is at http://rtmlusglysite.yahoo.com/store/XYZ01134 , you could host a simple PHP front-end at http:://www.example.com that would be acting like a "filtering" HTTP web proxy, so http://rtmlusglysite.yahoo.com/store/XYZ01134/item1234.rtml would be accessed by http://www.example.com/item1234.html
It's not an ideal solution, but it should work, and you could do some more fancy stuff.
Nice try from the other posters, but there is a very simple RTML command that will do it. . .
TEXT PAT-SUBST s GRAB
MULTI
HEAD
BODY
TEXT #var-with-alt-tag-equals-pad-in-it
frompat "alt=\"pad\""
topat ""
The above RTML will find all instances of alt="pad" and replace it with nothing.
Well you're right on RTML being relatively untraveled :)
Do you have a way to add your own attributes to these images tags? If so, would it be possible to override the alt attribute? If you specify alt="", I would think that would override Yahoo's... Otherwise consider putting a useful alt tag in there for the blind and dialup types.
It's the first time I'm hearing about this platform, but here is an idea: if you can add javascript to the pages, you could write a function that will run after the page has loaded and remove all the alt="pad" attributes from the page.
Unfortunately this solutions works only with browsers that know about scripting, so lynx or some other text based browsers might not support it.
I have shared a link official RTML guide from yahoo. Hope it will help. Thanks!
