Use urlrewrite to rewrite all requests to root - iis

Question

I want to use web.config and IIS's urlrewrite to rewrite all requests to a certain directory to the root, for example:
From:
mydomain.com/directory/test.php
To:
mydomain.com/test.php
and
From:
mydomain.com/directory/test/test.php
To:
mydomain.com/test/test.php
All parameters, etc should be passed as well. Any idea how to do this using web.config?

I had a requirement for this a while back and found this:
Using Url rewrite to "delete" a folder
There's a small error in the rule which was corrected later by the poster. Here's a copy with the correction should the link dry up (I also made it a bit more generic for your requirements):
<rewrite>
<rules>
<rule name="RemoveDirectory" stopProcessing="true">
<match url="^directory$|^directory/(.*)$" />
<conditions>
</conditions>
<action type="Redirect" url="{R:1}" />
</rule>
<rule name="RewriteToFile">
<match url="^(?!directory/)(.*)" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="directory/{R:1}" />
</rule>
</rules>
</rewrite>
Just search and replace directory with your directory name.
