c#

I have HTML in a string that looks like this:

<div id="control">
    <a href="/xx/x">y</a>
    <ul>
        <li><a href="/C003Q/x" class="dw">x</a></li>
        <li><a href="/C003R/xx" class="dw">xx</a></li>
        <li><a href="/C003S/xxx" class="dw">xxx</a></li>
    </ul>
</div>

I would like to change this to the following:

<div id="control">
    <a data-href="/xx/x" ><span>y</span></a>
    <ul>
        <li><a data-href="/C003Q/x" class="dw"><span>x</span></a></li>
        <li><a data-href="/C003R/xx" class="dw"><span>xx</span></a></li>
        <li><a data-href="/C003S/xxx" class="dw"><span>xxx</span></a></li>
    </ul>
</div>

I heard about regex but I am not sure how I can use it to change something inside the address tags and to change href at the same time. Would I need to use regex twice and can I change the inside of the <a ... >...</a> using regex or is there an easier way with C#?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
