I am trying to search people from Wikipedia(For example .*John.* in REGEX).

The following query is close, but it isn't generalized like .*John.* and only gives back historic figures that have passed(They only aren't Alphabetized).

Import["http://en.wikipedia.org/w/api.php?action=query&list=search&\srsearch=wikipedia&srprop=timestamp&eititle=Template:Persondata", "XML"]


The following query works although I can't seem to limit the results to people only.

Import["http://en.wikipedia.org/w/api.php?action=query&list=embeddedin&eititle=Template:Persondata&eilimit=100&format=xml&redirects", "XML"]

Although currently I'm running into Wikipedia API issues, I am looking for a way to get the results in Mathematica (and therefore I believe this question makes most sense on M.stackexchange).

This will download the titles of all articles that transclude the Persondata template, if that's what you're trying to do.

embeddedin&eititle=Template:Persondata&format=json&eilimit=500" <> 
      If[Length@# > 1, "&eicontinue=" <> #[[2, 2, 1, 2, 1, 2]], ""], 
     "JSON"] &, {}, Length@# != 1 &][[2 ;;, 1, 2, 1, 2, All, 3, 2]]

You can page through them manually here: https://en.wikipedia.org/w/index.php?title=Special:WhatLinksHere/Template:Persondata&limit=20&hideredirs=1&hidelinks=1

The API only lets you request 500 at a time though (and there are more than 1.1 million results), so expect to wait about 15 minutes or so.

I believe that only includes historical figures correct? –  Liam William Apr 5 at 2:03
Wikipedia is only supposed to include notable people. en.wikipedia.org/wiki/Wikipedia:Notability_%28people%29 –  Michael Hale Apr 5 at 2:06
+1 Although for example the list you show doesn't link to Aaron *? For example Aaron Swartz doesn't show on the list but he certainly has a wikipedia page. Somehow Wikipedia decides who to link to. In addition I was looking to search based on regex for example *name* –  Liam William Apr 5 at 2:12
The list is not alphabetical. I think it is in the order of the date a template was added to a page. Aaron Swartz is number 156433 in the list I got, and Select[list, StringMatchQ[#, "Aaron*"] &] // Length gives me 907. Some people add these templates to their user pages though, so you'll want to clear out ones that match "User:*", for example. I'm sure there are some other types of noise too. I use the API to work with the category system a lot, but people are split into many subcategories so you'd have to merge quite a few queries. –  Michael Hale Apr 5 at 2:35
I don't understand where you want to search for *name* though. –  Michael Hale Apr 5 at 2:40
