When I make api query sometimes I have list with few pages. For example
http://en.wikipedia.org/wiki/Ask gives a lot of pages, I need website "Ask.com, a web search engine, formerly Ask Jeeves"
can I make query only for some category ("websites")?
How I can check category for each page in response?
Thanks
There is no trivial way to do what you're asking. You could do something like this:
Get the list of pages the disambiguation page list. You could do this by listing the links on that page (action=query&prop=links).
Get the categories of all the pages from the previous step and use that to decide which one is the one you're looking for. This is not that simple, because Ask.com is not directly in Category:Websites, it's in one of its subcategories.
I have list with few pages, for example http://en.wikipedia.org/wiki/Ask
The problem is that you're not getting a list of pages, you just are getting an ordinary page which is in the disambiguation pages category. To get the list, you need to get the links in that page.
can I make query only for some category ("websites")?
No, mediawiki does not support that.
How I can check category for each page in response?
Use the links property as a title list generator and get the categories of each page in the response. In your case, that would be http://en.wikipedia.org/w/api.php?action=query&titles=Ask&generator=links&prop=categories (don't forget to continue the query).
If you are OK with "full-text search" for "ask",
you can do that like this:
http://en.wikipedia.org/w/api.php?format=json&action=query&generator=search&gsrsearch=ask%20incategory:%22Online%20companies%22&prop=info
As you can see, "search" text is [ask incategory:"Online companies"]

I want to extract the pages mentioned in the infobox and templates of pages.
E.g. From this page:
https://en.wikipedia.org/wiki/DNA
I want to extract all of the links in the infobox, like: "Genetics", "Introduction to Genetics" etc.
I want to do it, by using the sql dumps, possibly avoiding to parse the xml of whole pages, and I don't want to do it with APIs.
I could not find a way.
While Pagelinks does include also the links of infoboxes, I cannot find a way to exclude them.
I thought Templatelinks may have that info, but it is not: I could not find the pageids of the corresponding links in infoboxes.
Where is this information stored?
Or which kind of tables should I look at?
I consulted previous questions:
where can I find the infobox templates used in wiki?
and Mediawiki reference:
https://www.mediawiki.org/wiki/Manual:Templatelinks_table#Schema_summary
but could not find a solution.
That is a sidebar rather than an infobox: https://en.wikipedia.org/wiki/Template:Genetics_sidebar
I don't think there's a way of doing it other than parsing the content of the template to extract the links or using the API: e.g. https://en.wikipedia.org/w/api.php?action=query&prop=links&titles=Template:Genetics%20sidebar&pllimit=100&plnamespace=0
Something like this should also work but it's not returning any results for me:
SELECT * from pagelinks
where pl_title = 'Genetics_sidebar'
and pl_namespace = 0
and pl_from_namespace = 10

I'm creating a VCL Application with Delpi 10.3 and want to support some web functionality by having the user enter the ISBN of a book into a TEdit component and from there passing/sending this value to a search field on this website: https://isbnsearch.org after which the website looks up the ISBN and displays the Author of the book. I want to somehow access the information (i.e Author) presented by the search result and again use it in my application.
This is my GUI, for a better idea of what I want to accomplish:
What code can I use for this? Any other feasible suggestions or approaches are acceptable.
When performing a search on that website, it simply loads a page with a specific URL query string...
https://isbnsearch.org/search?s=suess
The above example is when I search for "suess", so you can easily concatenate a search URL.
You can use any HTTP component, such as TIdHTTP, to load this search page, then use an HTML parser to scrape the page and read what you need. Much, much easier than trying to read through the TWebBrowser.
In the end, you won't actually display the HTML (I mean you can if you want to), but the idea is to read the data and display it in your own format.
On that specific page, start by locating the ul element with id searchresults. Then, each li element contains individual results. Unfortunately, this website uses pagination, and only shows 10 results per page. To do this, call this page again with another parameter &p=2 for the 2nd page, &p=3 for the 3rd page, and so on.
On the other hand, that is the worst way to acquire such information. What you should be doing is using a proper API which gives you machine-friendly data. The service you are referencing doesn't appear to have an option, but here's an example of one which does:
https://openlibrary.org/dev/docs/api/books - this also appears to provide you MUCH more information than the one you're using.
Let's say I have a notebooks with name 'MyNotebook'. Now this notebook have a section group 'Group1' and now 'Group1' have another section group 'Group2'. Now inside 'Group2' I have section 'Section1' which has a page 'Page1'.
If we look this at like a directory structure the path to page will be -MyNotebook/Group1/Group2/Section1/Page1
When I try to get page using get page api I am able to get only immediate parent i.e Section1. So let's say I want get this complete hierarchy how I can get that ?
What API specifically are you using to get pages?
If you are using GET https://www.onenote.com/api/v1.0/me/notes/pages, this will give you all the pages, though that API has limitations (For example, it is paginated, so it will only give you the most recent 20 pages. In addition, it won't work if the user has a big number of sections).
https://blogs.msdn.microsoft.com/onenotedev/2017/07/21/a-few-performance-tips-for-using-the-onenote-api/
See the section "When getting all pages for a user, do so for each section separately"
I recommend you make a call like:
GET https://www.onenote.com/api/v1.0/me/notes/Notebooks?$expand=sections,sectionGroups($expand=sections,sectionGroups($levels=max;$expand=sections))
To obtain all the sections, and then make a call like:
GET https://www.onenote.com/api/v1.0/me/notes/sections/{id}/pages
To obtain each section's pages.
In addition to what Jorge said, if you specifically want the upwards hierarchy (and not downwards), you could do:
GET https://www.onenote.com/api/v1.0/me/notes/pages?$expand=parentSection($expand=parentSectionGroup($expand=parentSectionGroup($expand=parentNotebook)))
But as Jorge said, be careful when using the GET pages API since it has some limitations
I have a question regarding the meta property in php.
I have set
and I have a list of products that need to be displayed on the first page. Whwn I click the first product and click the like button the title that appears is different from the one I set, but when I click the other products and then click like I get the correct title. I tried clearing the cache but it didn't work and I tried verifying the link using http://developers.facebook.com/tools/debug and here it teels me that the title is the one I set.
Can anyone tell me what am I doing wrong or what might be the problem? Or maybe you have a soultion for this. :D
Thanks!
Without seeing the page which is being changed and liked, it's hard to know if I am answering your question, but the information may be useful to you anyway.
The issue may be with how many likes have already added up for the page.
Note that og:title and og:type are only editable initially - after
your page receives 50 likes the title becomes fixed
Source: https://developers.facebook.com/docs/opengraphprotocol/
This has happened to me before. The easy fix/workaround I found was this: I had been appending a query string to the page URL for tracking some stats. That URL with the query string had over 50 likes. Once I changed the query string, or left it off, the page had a different amount of likes. So when I used the Facebook linter/debugger, I used the new URL and it picked up my og:title and description change.
Are you able to post a link to the page you are having this issue with?
I'm not quite sure if this is possible in MediaWiki.
I've got several categories, each containing a few pages. If you open a category page you'll see the contents of the category that usualy consists of these three parts:
A user defined text (which can be edited by using the edit link).
All subcategories that are attached to this category.
All pages that are attached to this category.
My goal is to create a page that includes at least part #3 of several categories. A page that shows me all page names that are attached to multiple categories of my choosing, grouped by their category.
My first approach was to use the standard transclude syntax of MediaWiki:
Category A contains these pages:
{{:Category:A}}
Category B contains these pages:
{{:Category:B}}
Category C contains these pages:
{{:Category:C}}
...
Unfortunatly, this only transcluded part #1 of a category: the user defined text. The page name listing was missing.
My second idea was to have a look at the parser functions. Perhaps there are some functions that offer enumerating through the pages of a category. But I didn't find any.
Perhaps there is a MediaWiki extension out there...
Is there a clever way to realize this?
Try http://www.mediawiki.org/wiki/Extension:CategoryTree, with the following syntax:
Category A contains these pages:
<categorytree hideroot="true" namespaces="-">Category A</categorytree>
If you want more control over how the results are displayed, you may want to give Semantic Mediawiki a try.
The syntax would look something like:
Pages in Category A:
{{#ask:[[Category:A]]
|format=ul
}}
Even if you are not using semantic properties, you can use the query mechanism to display pages based on categories.
The MediaWiki extension Dynamic Page List (http://www.mediawiki.org/wiki/Extension:DynamicPageList_(third-party)) does this with ease, producing bulleted lists of articles in a category:
Pages in Category A:
<dpl>
category=A
</dpl>
without a heavyweight solution like Semantic MediaWiki. Just install and go.
DPL has a rich syntax for more powerful dynamic lists. For example, to produce a numbered list in 3 columns:
<dpl>
category=A
mode=ordered
columns=3
</dpl>
