How can I export table row in internet explorer?

Question

I need to export a single table row on a website and I can't figure out how to do it.  The source view for the row I need is:
tr class="alt">
<td id="16ZwhxLjCN8fafA8wuYEnMFtGJGrFy6qcE">16ZwhxLjCN8fafA8wuYEnMFtGJGrFy6qcE</td>
<td></td>
<td></td>
<td>0.00065227</td>
<td>0.01233629</td>
<td>0.00371003</td>
</tr>I can get the table ID using the code below, but I don't know how to get the rest of the values. The table ID does not change but the numerical values do.$ie = New-Object -com InternetExplorer.Application
$ie.silent = $false
$ie.navigate2("mywebsite.com")
$ie.Document.getElementById("16ZwhxLjCN8fafA8wuYEnMFtGJGrFy6qcE")

Hi Tom,
this may not be quite the perfect solution, but it works for me at least. I'm not using the IE ComObject, but rather the .NET Webclient for it ...
# Load downloader function
function Get-WebContent
<#
.SYNOPSIS
Downloads a file
.DESCRIPTION
Download any file using a valid weblink and either store it locally or return its content
.PARAMETER webLink
The full link to the file (Example: "http://www.example.com/files/examplefile.dat"). Adds "http://" if webLink starts with "www".
.PARAMETER destination
The target where you want to store the file, including the filename (Example: "C:\Example\examplefile.dat"). Folder needs not exist but path must be valid. Optional.
.PARAMETER getContent
Switch that controls whether the function returns the file content.
.EXAMPLE
Get-WebContent -webLink "http://www.technet.com" -destination "C:\Example\technet.html"
This will download the technet website and store it as a html file to the target location
.EXAMPLE
Get-WebContent -webLink "www.technet.com" -getContent
This will download the technet website and return its content (as a string)

$file = $webclient.DownloadString($webLink)
if ($destination -ne "")
try {Set-Content -Path $destination -Value $file -Force}
catch {}
if ($getContent){return $file}
# Download website
$website = Get-WebContent -WebLink "http://www.mywebsite.com" -GetContent
# Cut away everything before the relevant part
$string = $website.SubString($website.IndexOf('<td id="16ZwhxLjCN8fafA8wuYEnMFtGJGrFy6qcE">'))
# Cut away everything after the row
$string = $string.SubString(0,$string.IndexOf('</tr>'))
# Split the string into each individual line
$lines = $string.Split("`n")
# Prepareing result variable
$results = @()
# For each line, cut away the clutter
foreach ($line in $lines)
$temp = $line.SubString(4,($line.length - 10))
# for the first line, the td has an id, which this compensates for
if ($temp -like 'id="16ZwhxLjCN8fafA8wuYEnMFtGJGrFy6qcE">*'){$temp = $temp.SubString(($temp.IndexOf(">") + 1))}
# Add cleaned line to results
$results += $temp
You may need to adapt the string parsing beneath the function, if the text you posted is not literally identical to the way this function returns it. It worked for a string block acquired via copy&paste from your post anyway. :)
I certainly would be more than happy to read a more elegant version, if someone has one to offer.
Cheers,
Fred
