Regex匹配Wikipedia内部文章链接。

I want to regex match text in Wikipedia article source code with following rules:

我想要regex匹配*文章源代码中的文本，并遵循以下规则:

---

1. Match only links to internal articles. So don't match links with any namespaces like files, categories, users, ... etc (complete list of these namespaces here)
   • Example link to match [[Without|namespace]]
   • 匹配[[没有|命名空间]的示例链接]
   • Example links NOT to match [[Category:Nope]], [[File:Nopeish]] etc.
   • 示例链接不匹配[[类别:不]]、[[文件:Nopeish]]等。
2. 只匹配到内部文章的链接。因此，不要将链接与任何名称空间(如文件、类别、用户等)匹配。etc(这里列出这些名称空间的完整列表)示例链接以匹配[[[没有|命名空间]]]]示例链接不匹配[[[Category: no]]， [[File:Nopeish]]等。

---

2. Match only links having delimiter "|". Links with this symbol are displayed in article with different text as the title of article they are referring to
   • Example link to match [[Something|else]]
   • 示例链接以匹配[[某个|else]]
   • Example link NOT to match [[text]]
   • 示例链接不匹配[[text]]
3. 只匹配具有分隔符“|”的链接。与此符号的链接在文章中以不同文本作为文章标题显示，它们引用示例链接来匹配[[|else]]]示例链接不匹配[[text]]

---

3. Match links in two groups
   • Example link to match [[Something|else]] will be matched into two groups with text:
     1. group: "Something"
     2. 组:“东西”
     3. group: "else"
     4. 组:“其他”
   • 匹配的示例链接[[Something|else]]将被匹配为两个组，文本为:group: "Something" group: "else"
4. 在两个组的例子中，Match链接将被匹配为两个组:组:“Something”组:“else”

---

I have tested this and so far I've come up with following regex: \[\[(?!.+?:)(.+?)\|(.+?)\]\] which is not working as expected since it also matches text like this:

我已经测试过了，到目前为止，我已经找到了以下的regex: \[\]\ [(?! +?:) \ (.+?)\|(.+?)\]\

[[Problem]] non link text [[Another link|problemAgain]]
  ^------------ group 1 (wrong) -------^ ^-group 2 -^

[[This should be|matched|]]

Just use a negated character class instead of .+?,

用一个否定的字符类代替。

\[\[(?!.+?:)([^\]\[]+)\|([^\]\[]+)\]\]

Java regex would be,

Java正则表达式,

"\\[\\[(?!.+?:)([^\\]\\[]+)\\|([^\\]\\[]+)\\]\\]"

simply you could do like this,

你可以这样做，

\[\[([^\]\[:]+)\|([^\]\[:]+)\]\]
