Guidance Request (and a specific question)

I am wondering if JavaScript is a reasonable way to solve my problem. I
have to snatch some info from a web page and build a report. Some of the
info comes from the web page and some will be supplied by the end user.
This process will be initiated by the end user clicking on a menu item in
the IE (6.0) Tools menu. I will need to access the html of the web page and
then solicit some input from the end user via some form or something
similar. I know that's rather vague but does it seem feasible?

Thus far I am trying to access the html of the page and it's been tough
going. One of the bits of info I want to snatch from a web page is a
telephone number, which, on one of the web sites, looks like this ...

<table cellpadding='0' cellspacing='0' align='center'>
<tr>
<td align='center' class='class_20' >Telphone: <span class='class_23'
style="font-size:14px;font-weight:bold;">111-222-3333</span></td>
</tr>
</table>

After reading the first few chapters in a JavaScript book and looking at
some DOM reference material, I've, so far, got the following:

<script type="text/javascript">
var parentwin = external.menuArguments;
var doc = parentwin.document;
var x = doc.getElementsByTagName("td")
alert(x.length + " td things")
// alert(x[0].toString)
for (whatever in x)
{ alert(whatever.nodeName)
}
</script>

I've tried many, many things but I have been unable to find the text I am
after - in this case "Telephone:" and the telephone number, "111-222-3333".
The objects returned by getElementsByTagName don't seem to have a toString
method, which I had hoped would give me "<td ... </td>". I am currently
trying to learn something about DOM "nodes" - but I am not at all sure that
that will be the answer. So, the specific question I promised - how do I
grab the strings "Telephone:" and "111-222-3333" from the html shown above.

Thanks for whatever help, pointers, sympathy you are kind enough to provide.

With IE's HTML DOM the element nodes have properties innerText,
innerHTML and outerHTML. Also table elements objects have a rows
collection and rows have a cells collection. That way
var table1 = doc.getElementsByTagName('table')[0];
var cell1 = table1.rows[0].cells[0];
var text = cell1.innerText;
That cell above has a couple of child nodes, its firstChild is a text
node with the text "Telphone: ", its second child is a span element so
you could use
var text1 = cell1.firstChild.nodeValue;
and
var text2 = cell1.childNodes[1].innerText;
to have text1 hold the text "Telphone: " and text2 hold the text
"111-222-3333"
