If I have a HTML file on disk, How can I read it all at once in to a String variable at run time? Then I need to do some processing on that string variable. 

Some html file like this:

```
<html>
    <table cellspacing="0" cellpadding="0" rules="all" border="1" style="border-width:1px;border-style:solid;width:274px;border-collapse:collapse;">
        <COLGROUP><col width=35px><col width=60px><col width=60px><col width=60px><col width=59px></COLGROUP>
        <tr style="height:20px;">
            <th style="background-color:#A9C4E9;"></th><th align="center" valign="middle" style="color:buttontext;background-color:#D3DCE9;">A</th><th align="center" valign="middle" style="color:buttontext;background-color:#D3DCE9;">B</th><th align="center" valign="middle" style="color:buttontext;background-color:#D3DCE9;">C</th><th align="center" valign="middle" style="color:buttontext;background-color:#D3DCE9;">D</th>
        </tr><tr style="height:20px;">
            <th align="center" valign="middle" style="color:buttontext;background-color:#E4ECF7;">1</th><td align="left" valign="top" style="color:windowtext;background-color:window;">Hi</td><td align="left" valign="top" style="color:windowtext;background-color:window;">Cell Two</td><td align="left" valign="top" style="color:windowtext;background-color:window;">Actually a longer text</td><td align="left" valign="top" style="color:windowtext;background-color:window;">Final Word</td>
        </tr>
    </table>
</html>

```
