  • Fetch excerpt from Wikipedia article?

    - by Felix
    I've been up and down the Wikipedia API, but I can't figure out if there's a nice way to fetch the excerpt of an article (usually the first paragraph). It would be nice to get the HTML formatting of that paragraph, too. The only way I currently see of getting something that resembles a snippet is by performing a fulltext search (example), but that's not really what I want (too short). Is there any other way to fetch the first paragraph of a Wikipedia article than barbarically parsing HTML/WikiText?

  • HTML or Alternate markup for wiki site?

    - by at
    In choosing an editor for my wiki-like site, I'm debating whether to allow HTML or a custom alternate markup (maybe like wikipedia/wikimedia's or BBCode). HTML benefits: Easy for users to deal with (copying and pasting, learning) Somewhat future proof Many more editing tools available, usually WYSIWYG too Alternate markup benefits: On the server side I don't have to worry about parsing malicious javascript or styles or HTML that I don't allow Can be easy to learn Can be easier to decipher if not HTML-savvy Am I missing something, what's the best solution?

  • HTML parser for GAE

    - by Richard
    Generally I use lxml for my HTML parsing needs, but that isn't available on Google App Engine. The obvious alternative is BeautifulSoup, but I find it chokes too easily on malformed HTML. Currently I am testing libxml2dom and have been getting better results. Which pure Python HTML parser have you found performs best? My priority is the ability to handle bad HTML over speed.

  • Solve math question in PHP

    - by Koning WWWWWWWWWWWWWWWWWWWWWWW
    The user can enter a math problem like 5 + 654, 6 ^ 24, 2!, sqrt(543), log(54), sin 5, sin(50). After some reformatting (e.g. change sin 5 into sin(5)), and doing an eval, PHP gives me the right result. However, this is quite unsafe. Can anyone point me in the right direction parsing and solving a math question like the examples above, which is safe? Thanks.

  • What quality, parser-generator options exist for ruby?

    - by cartoonfox
    What open source (preferably gem-based) parser-generator options do I have in Ruby? I've used (flex&bison)|(lex&yacc) from C in the past, and I'm comfortable with BNF-style specifications. I've heard of treetop, but it looks a bit alien and verbose compared to yacc... Purpose: I want to convert my text markup language to a BNF and generate the parsing code. I think it's a better strategy than my first-order solution: http://github.com/dafydd/semantictext/blob/master/lib/semantictext/rich_text_parser.rb

  • is there any faster way to parse than by walk each byte?

    - by uray
    is there any faster way to parse a text than by walk each byte of the text? I wonder if there is any special CPU (x86/x64) instruction for string operation that is used by string library, that somehow used to optimize the parsing routine. for example instruction like finding a token in a string that could be run by hardware instead of looping each byte until a token is found.

  • What is the best way to modify a few fields in an XML using Java

    - by Kailas J C
    I have a big XML which contains around 300 elements. I need to modify 2 or 3 elements in this xml using Java. I don't want to go for conventional marshalling and unmarshalling as it involves the parsing of the whole XML. How is XPath/XSLT manipulation? I know that I can easily read the data but i need to modify the same and put in back in the same XML. The primary concern here is performance. Kindly advise

  • Preventing access to files if a user types the full url on the address bar

    - by bogha
    i have a website, some folders on the websites contains images and files like .pdf , .doc and .docx . the user can easly just type the address in the url to get the file or display the photo http://site/folder1/img/pic1.jpg then boom.. he can see the image or just download the file my question is: how to prevent this kind of action, how can i guarantee a secure access of the files. any suggestions UPDATE TO CLARIFY MY IDEA i don't want any user who is browsing the website to get access to these files normally by just writing the URL of the file. those files are a CV files, they are being uploaded by the users to a specific folder on the server which we host outside the company. those files are only being viewed by the HR people through a special system. that's the scenario we want. i don't want a WEB GEEK who just wants to see what files has been uploaded to this folder to download them easly to his/her computer and view them or publish them on the internet. i hope you got my idea

  • Getting around url block for game

    - by Josh T
    So I play a game called Battlefield Play4Free (www.battlefield.play4free.com). Its essentially a giant browser plugin. The admin on my computer used to have the url battlefield.play4free.com/en/playnow.html blocked which only blocked the page that launches the game (i found a way to launch the game without going to that page and the game worked fine). Now it blocks battlefield.play4free.com which thus blocks all subpages. However, I have found that if I change it to an https and go to https://battlefield.play4free.com/en/login.html to login and then https://battlefield.play4free.com/en/playnow.html I can launch the game. However, when the game launches the borders and everything show but the window content is just a giant blockpage (the same one that shows up when I go to battlefield.play4free.com in the browser) and the blocked page is battlefield.play4free.com (main page). Is there any way I can get around this? I need a way to make the game access the server without going through the browser i.e. make the game use a proxy to get the data or somehow get past the besafe block. I was thinking perhaps you could get around it if you could get the game to make a direct request to the server and not through the url/browser, I know this works because I have a torrenting app that even tho torrent sites are blocked in the browser, the app makes a direct request and thus is not blocked. By the way, the program that blocks everything is besafe or besecure something like that. I do have access to an admin account (on the computer not the besafe program) as well as router access and pretty much anything else. Thanks so much!
