div标签的递归正则表达式（不试图用正则表达式解析html）

Question

I have a bunch of wiki markup, sometimes people just throw random html down in the middle of wiki markup and somehow wikipedia just rolls with it, as it does for all kinds of other badly formed wiki markup. I want to match everything inside the divs.

I need to recursively find all the <div>blah</div> tags including div tags with other div tags inside them. I am trying to match the div tags and everything inside of them. I have this which I believe almost works:

new Regex(@"\<div.*?\> (?<DEPTH>)                   # opening 
            (?>                # now match...
               [^(\<div.*?\>)(\<\/div\>)]+          # any characters except divs
            |                  # or
               \<div.*?\>  (?<DEPTH>)  # a opening div, increasing the depth counter
            |                  # or
               \<\/div\>  (?<-DEPTH>) # a closing div, decreasing the depth counter
            )*                 # any number of times
            (?(DEPTH)(?!))     # until the depth counter is zero again
          \<\/div\>                   # then match the closing fix",
            RegexOptions.IgnorePatternWhitespace | RegexOptions.Compiled | RegexOptions.IgnoreCase | RegexOptions.Singleline);

Maybe I should be using another methodology to parse this but at this point this is the final regex statement that I need.

Here is an example:

<div class="infobox sisterproject" style="font-size: 90%; padding: .5em 1em 1em 1em;">
<div style="text-align:center;">

Answer 1

我认为使用正则表达式解析html并不是一个好主意，你可以使用Html Agility包

Answer 2

 new Regex(@"<div\b[^>]*>(?><div\b[^>]*>(?<DEPTH>)|</div>(?<-DEPTH>)|.?)*(?(DEPTH)(?!))</div>", RegexOptions.IgnorePatternWhitespace | RegexOptions.Compiled | RegexOptions.IgnoreCase | RegexOptions.Singleline);

在我修复表达式的时候，我甚至不会完成html敏捷包装和工作的一半。
