Need to extract abstract of a wikipedia page
by aditya srinivas 23 Nov '23

23 Nov '23

Hello, I am writing a Java program to extract the abstract of the wikipedia page given the title of the wikipedia page. I have done some research and found out that the abstract with be in rvsection=0 So for example if I want the abstract of 'Eiffel Tower" wiki page then I am querying using the api in the following way. http://en.wikipedia.org/w/api.php?action=query&prop=revisions&titles=Eiffel… and parse the XML data which we get and take the wikitext in the tag <rev xml:space="preserve"> which represents the abstract of the wikipedia page. But this wiki text also contains the infobox data which I do not need. I would like to know if there is anyway in which I can remove the infobox data and get only the wikitext related to the page's abstract Or if there is any alternative method by which I can get the abstract of the page directly. Looking forward to your help. Thanks in Advance Aditya Uppu

Retrieving images instead of math markup
by Gabriel Sandor 20 Jan '11

20 Jan '11

Hi everyone, Is it possible to retrieve (preferably via the MediaWiki API) an image representing a mathematical formula given in the <math> tags that are frequently encountered in Wikipedia articles ? It would be very helpful if there were a way to "expand" these tags directly into images, similarly to how the "templates=expand" string appended to the query string automatically expands most of the templates in an article's wikitext; otherwise, a section of the API or of the site (such as a Special page) that can make this conversion for individual fragments would also be very helpful. Thanks in advance, Gabriel

the meaning of registration and editcount
by Raymond Yee 14 Dec '10

14 Dec '10

Hi everyone, I have a question about two properties you can query about a user account: the "editcount" and the "registration". If you look at http://en.wikipedia.org/w/api.php for the *list=users* method, you see editcount - adds the user's edit count registration - adds the user's registration timestamp My naive interpretation is that editcount is the total number of edits made a given user (including the number of and registration is the time when the account was setup.) Therefore, if you use *list=usercontribs* method, two things should be true: 1) the editcount should be greater to or equal to the number of edits (usercontribs) for the given user I can get from the API. (As an ordinary user of the API, I won't be able to uncover deleted edits and therefore the editcount might exceed the count of edits from *list=usercontribs* ) and 2) the timestamp of all edits for a given user account cannot be earlier than the registration timestamp for that account. (That is, how can an account be editing before the account was actually registered.) In computing statistics for many recent accounts, I have these assumptions to be true for the vast majority of accounts. I'm puzzled, however, for accounts in which one or both assumptions are wrong. An example is User:Katr67 http://en.wikipedia.org/w/api.php?action=query&list=users&ususers=Katr67&us… yields: <?xml version="1.0"?> <api> <query> <users> <user name="Katr67" editcount="4" registration="2010-12-10T08:09:19Z" /> </users> </query> </api> But if you look at the list of contributions by User:Katr67 at http://en.wikipedia.org/w/index.php?limit=50&tagfilter=&title=Special:Contr… -- you'll find more than 4 edits (contrary to assumption #1) and edits earlier than Dec 10 (contrary to assumption #2). From http://toolserver.org/~soxred93/pcount/index.php?name=Katr67&lang=en&wiki=w… we can see that there are 504 edits attributed to User:Katr67 (something one can verify through using http://en.wikipedia.org/w/api.php?action=query&list=users&ususers=Katr67&us… or mwclient -- e.g.: len(list(mwclient.Site("en.wikipedia.org").usercontributions(user="Katr67"))) (which returned 504) So, what do *editcount* and *registration* really mean then? (For User:Katr67, it looks like there was some change to the account on Dec 10, which reset the registration timestamp and editcount to the last 4 edits. ) Thanks, -Raymond (User:RaymondYee)

action=edit using curl
by Tim McKenna 14 Dec '10

14 Dec '10

When I post from a form I have no trouble having action=edit work. But when I send the same $postdata through a curl script I get: error code="badtoken". <? $qstr=file_get_contents("php://input"); $url = "http://localhost:8888/hosted/hum211/api.php?action=edit"; $ch = curl_init(); // initialize curl handle curl_setopt($ch, CURLOPT_URL,$url); // set url to post to curl_setopt($ch, CURLOPT_FAILONERROR, 1); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);// allow redirects curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable curl_setopt($ch, CURLOPT_TIMEOUT, 3); // times out after 4s curl_setopt($ch, CURLOPT_POST, 1); // set POST method curl_setopt($ch, CURLOPT_POSTFIELDS, $qstr); // add POST fields $result = curl_exec($ch); // run the whole process curl_close($ch); echo $result; ?> To check I tried sending both not to api.php but to some php that would just display the postfilelds. They look exactly alike. Not sure what to do next. Timothy S.

API bug with page titles with & in them ?
by Nicolas Vervelle 12 Dec '10

12 Dec '10

Hi, I made a few attempts but didn't success to use the API with page titles containing a & in them. I tried replacing it with %26 in the request but it seems to work only for some requests... For example, the following request seems to work: http://en.wikipedia.org/w/api.php?action=query&titles=Rollin' %26 Coastin' (In Search of America)&prop=info&inprop=protection|talkid<http://en.wikipedia.org/w/api.php?action=query&titles=Rollin'%20%26%20Coastin'%20(In%20Search%20of%20America)&prop=info&inprop=protection|talkid> I get the informations about page "Rollin' & Coastin' (In Search of America)" But, the following request tells that the page is missing http://fr.wikipedia.org/w/api.php?rvprop=content|ids|timestamp&inprop=prote…' %26 Coastin' (In Search of America) The requests says that page "Rollin' & Coastin' (In Search of America)" is missing Am I missing something or is there a bug in the API ? Thanks, Nico

[Mediawiki-api-announce] BREAKING CHANGE: patrol tokens change again; action=patrol requires POST
by Roan Kattouw 10 Dec '10

10 Dec '10

2010/10/23 Roan Kattouw <roan.kattouw(a)gmail.com>: > As of r75274, patrol tokens accepted by action=patrol and generated by > list=recentchanges are no longer equal to edit tokens and are no > longer the same within a session. Instead, they are now different for > every recentchanges row (i.e. they depend on the rcid). > > It may take a while for this change to be deployed to the Wikimedia > cluster, but in the meantime changing your clients to no longer depend > on the patrol token to stay the same can't hurt. > This has changed again in r78141. Patrol tokens no longer depend on rcid; instead, they are the same throughout the session (like the edit token is), but NOT equal to the edit token. Also, api.php?action=patrol now only accepts POST requests. The changes in r75274 were never part of any release and were never deployed to Wikimedia wikis.
