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

[Mediawiki-api-announce] BREAKING CHANGE: cltype parameter ignored when clsort=timestamp is set
by Roan Kattouw 28 Mar '11

28 Mar '11

As of r84905 [1] (going live to Wikimedia within the hour), the cltype parameter to list=categorymembers is ignored when clsort=timestamp is set. This change is needed for performance reasons: long-running queries were causing bug 28291 [2] on Wikimedia wikis. This does not break backwards compatibility with any released version of MediaWiki, because cltype is new in 1.17. Functional cltype=foo&clsort=timestamp behavior was only live on Wikimedia wikis for about 2-3 weeks.

Extracting data for transcluded Y/N for a series of pages
by Billinghurst 28 Mar '11

28 Mar '11

At Wikisource we do a lot of work proofreading in our Page: ns, with the pages being "held together" by an overarching page in the Index: namespace. Principally the text gets proofread and the validated in the Page: pages and later transcluded into the main namespace (our presentation layer). A transclusion can be a part of a page, a whole page, or a series of pages depending on the work being reproduced, and how we are choosing to present it. What I would like to do per work is to determine which pages are and which are not transcluded a yes/no answer, rather than to know to where the page is transcluded. At the moment, my only means to determine if a page is trancluded is to individually check each page via WhatLinksHere, and I am looking for an easier way to determine the Y/N answer, so I am looking for an easy way to dynamically determine this for a series of pages. Ultimately my ideal outcome is to have a link on the Index: page that could easily show which pages are and which pages are not transcluded. I know what I want, however, I no idea to get either the API to work for me, or to work out how to do it for a series of pages. Hence I am here to ask for some guidance and assistance. Examples based on the work of vol. 32 of the Dictionary of National Biography * Index:Dictionary of National Biography volume 32.djvu https://secure.wikimedia.org/wikisource/en/wiki/Index:Dictionary_of_Nationa… ==Transcluded page== * Page:Dictionary of National Biography volume 32.djvu/163 https://secure.wikimedia.org/wikisource/en/wiki/Page:Dictionary_of_National… https://secure.wikimedia.org/wikisource/en/w/api.php?action=query&generator… <?xml version="1.0"?> <api> <query> <pages> <page pageid="554940" ns="0" title="Laski, John (DNB00)" touched="2011-03-14T21:59:25Z" lastrevid="2341119" counter="" length="341" /> </pages> </query> </api> ==Non-transcluded page== * Page:Dictionary of National Biography volume 32.djvu/263 https://secure.wikimedia.org/wikisource/en/Page:Dictionary_of_National_Biog… https://secure.wikimedia.org/wikisource/en/w/api.php?action=query&generator… <?xml version="1.0"?> <api /> Thanks in advance for any guidance.

Is there an advantage to putting parameters in the URL?
by richardcavell＠mail.com 26 Mar '11

26 Mar '11

Hi, everyone. My Wikipedia bot used to access Wikipedia by putting parameters into URLs, like this: http://en.wikipedia.org/w/api.php?action=query&prop=info%7Crevisions&intoke… I put some parameters into POST data, though. Firstly, anything that I think ought to be kept relatively secret (such as login password), and secondly, anything that might be long (such as edited text or even edit summaries). Today I converted my bot to use bare URLs and put all the parameters in POST. Yet, I wonder if I should have an option in my bot for the user to use URL parameters instead of POST parameters. Bear in mind that although I'm coding with Wikipedia in mind, my bot is open source and intended to be used with any Mediawiki project. I can see that there are avantages to putting parameters into POST data. Are there any advantages to a bot putting parameters into the URL? Richard

Maximum length of various strings
by richardcavell＠mail.com 23 Mar '11

23 Mar '11

Hi everyone, I have written a Wikipedia bot. It obviously does a fair amount of work with strings. I'd like to know what are MediaWiki's or Wikipedia's limits for the size of these strings. For example, I have found documentation that states that edit summaries are limited to 200 characters. (I'm not sure if that includes a terminating zero or not). Where can I find the maximum size for: URL page title page content (wikitext and HTML versions) HTTP response from server edit token login token username etc. Richard

Portals vs categories
by Robert Crowe 20 Mar '11

20 Mar '11

I'm able to list the categories that a page belongs to, and the categories that a category contains. I'm also able to list the portals that a category contains, but I can't seem to find a way to list the portals that a page or category belongs to. Is there a way to do that? Thanks in advance, Robert

How to do 2 queries in one
by richardcavell＠mail.com 13 Mar '11

13 Mar '11

Hi everyone. I'm building a Wikipedia bot. My bot finds out the timestamp and author of the current version of a page in one query, like this : http://en.wikipedia.org/w/api.php?action=query&prop=revisions&format=xml&ti… If there is vandalism on the page, it attempts to find out the revid and name of the author of the previous author of the page, like this : http://en.wikipedia.org/w/api.php?action=query&prop=revisions&format=xml&rv… If there is no other author other than the current author, then it will not give a result. Note that the previous author may be 1 or 10 revisions ago - it simply means the person who edited it most recently other than the current author. Now, is there a way for me to combine these queries into one? That is, can I get the present author of the page and the previous author in one call, knowing that the present author may be responsible for 1 or several revisions, and that there may be no previous author ? Richard

Determine whether current user can edit specified page
by Jim Safley 08 Mar '11

08 Mar '11

Hello, Using the API, what is the best way to determine whether the current user can edit a specified page? I could use: ?action=query&prop=info&intoken=edit&titles={title} to detect an "Action 'edit' is not allowed for the current user" warning, but this doesn't account for users with edit rights who attempt to edit a protected page. Thanks, Jim

BREAKING CHANGE: list=filearchive filtering parameters removed
by Bryan Tong Minh 07 Mar '11

07 Mar '11

In r83410/r83411 I have disabled filtering by size (faminsize/famaxsize) and by hash (fasha1/fasha1base36) for list=filearchive because of performance problems. It is possible that filtering by hash will return at a later point, but filtering by size has gone for good. Affected wikis are those that run on version 1.17. This includes Wikimedia, to which this change will be deployed this week. Best regards, Bryan Tong Minh
