How to write a regular expression in c# to match internal links to articles in Wikipedia?

Question

I need to write a regular expression that scan the html code (the string) of an article in Wikipedia for links to other articles in Wikipedia.

The links usually look like these for example:

<a href="/wiki/English Language" title="English Language">English</a>

<a href="/wiki/Spanish Language" title="Spanish Language">Spanish</a>

I tried the regular expression: "<a.*href=(\"|')(.+?)(\"|')*wiki.*>" it works, but it also matches links to images and not just articles.

1. What have you tried doing? 2. *Why* would you want to use regular expressions for this? — UnholySheep, Apr 24 '17 at 06:28
Thank you all, for the answers. I added the regular expression that i tried, it works, but it also find images, i don't know how to change it that it will match only articles. — Michelle, Apr 24 '17 at 08:46
you can add a restriction in the regex to filter out the images, something similat to `]*href=['"](?!http)[^'"]+['"]`. Changing the `http` with the images types. — Cleptus, Apr 24 '17 at 10:26

I finally succeed. I wrote a regular expression for the beginning of the link:

(@"<a href=""/wiki/[A-Z][A-Za-z0-9\-\-_]+""")
