Regex paterns to remove word formatting

I am having a problem using regex patterns to replace items in HTML markup. The values that I am trying to replace are these:

<!--[if mso 9]-->
<style>
 p.MsoNormal<br />
 {margin-left:18.75pt;}<br />
</style>
<!--[endif]-->

and

class="MsoNormal"

I am not the best at using Regex the patterns that I have come up with so far are:

  1. <!--(.*?)-->
  2. class=\"msonormal\"
  3. class=\"MsoNormal\"

Item 1 removes anything that starts with <!-- and ends with --> but it only does it once it doesn't remove all instances.

I don't think items 2 and 3 are working at all.

I found some of this information for the patterns here:

is there a Way to strip all Unnecessary MS Word Formatting from FCKEditor

The full listing of text that I want to remove is this:

    <!--[if !mso]><style>v\:* {behavior:url(#default#VML);}
o\:* {behavior:url(#default#VML);}
w\:* {behavior:url(#default#VML);}
.shape {behavior:url(#default#VML);}
</style><![endif]-->
<title>Blank</title>
<style>
    <!--

Try this pattern for catching the first group of items:

\<\!\-\-\[i[\w\s\p{P}\p{S}]+if\]\-\-\>

The point is to avoid .* as far as possible for it will eat the whole input string hence the ending criteria is not matched.

For the 2nd and 3rd, you only need to escape the = sign as in \=. They would be fine, however try the following pattern to catch other Mso* classes too:

class\=\"Mso[^\"]+\"

Usually, when you want a Regexp to run over each possible instance, you need to add the "g" operator, meaning global. In C#, what you usually do is use Regexp.matches() to find every instance and then operate on them.

As for the class="MsoNormal", I can't find any instance of that in your text. Are you sure you're searching for the correct pattern?
