Edit lines in file preserving part of it
Hello:
I have the following HTML table:
Code:
<table>
    <thead>
        <tr>
            <th>Code</th>
            <th>Percentage</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>1</td>
            <td>30%</td>
        </tr>
        <tr>
            <td>2</td>
            <td>70%</td>
        </tr>
    </tbody>
 </table>

I would like to add a button with an event to every <td> element with a code, like the following:
Code:
<table>
    <thead>
        <tr>
            <th>Code</th>
            <th>Percentage</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td><button onclick="reset(1)">Reset</button>1</td>
            <td>30%</td>
        </tr>
        <tr>
            <td><button onclick="reset(2)"></button>2</td>
            <td>70%</td>
        </tr>
    </tbody>
 </table>

Note that I'm not asking how to parse the HTML. Instead, I would like to know how to replace every \t\t\t<td>x</td> line by \t\t\t<td><button onclick="reset(x)">x</button></td>, where x is the code number.

I need to do it with a command-line text editor without input from the user, because I have many files like this one and my idea is to edit all of them using find with the -exec option.

This would be a simple task with ex or ed if I just had to replace the same concurrence. But in this case, I need to keep the code in every replacement. That's what I'm struggling with. I'm afraid I'll need advanced tools like awk and I honestly don't know how to do it.

How can I add the button with the event to the table cells?
Thanks in advance.

vend::table::editor

Vend::Table::Editor(3pm)				User Contributed Perl Documentation				  Vend::Table::Editor(3pm)

NAME

       Vend::Table::Editor -- Interchange do-all HTML table editor

SYNOPSIS

       [table-editor OPTIONS]

       [table-editor OPTIONS] TEMPLATE [/table-editor]

DESCRIPTION

       The [table-editor] tag produces an HTML form that edits a database table or collects values for a "wizard". It is extremely configurable as
       to display and characteristics of the widgets used to collect the input.

       The widget types are based on the Interchange "[display ...]" UserTag, which in turn is heavily based on the ITL core "[accessories ...]"
       tag.

       The "simplest" form of "[table-editor]" is:

	       [table-editor table=foo]

       A page which contains only that tag will edit the table "foo", where "foo" is the name of an Interchange table to edit. If no "foo" table
       is "defined", then nothing will be displayed.

       If the "mv_metadata" entry "foo" is present, it is used as the definition for table display, including the fields to edit and labels for
       sections of the form. If "ui_data_fields" is defined, this cancels fetch of the view and any breaks and labels must be defined with
       "ui_break_before" and "ui_break_before_label". More on the view concept later.

       A simple "wizard" can be made with:

	       [table-editor
			       wizard=1
			       ui_wizard_fields="foo bar"
			       mv_nextpage=wizard2
			       mv_prevpage=wizard_intro
			       ]

       The purpose of a "wizard" is to collect values from the user and place them in the $Values array. A next page value (option mv_nextpage)
       must be defined to give a destination; if mv_prevpage is defined then a "Back" button is presented to allow paging backward in the wizard.
