Reading INI files with dashes in the section name

Question

I am trying to read an INI file from a web site. Within that INI file are sections that have dashes in them. I need to be able to read several sections so I can locate specific files to download referenced within the INI files. I found a script for parsing
INI files, but when I run it, the script fails to handle the sections that have dashes. Any ideas on how I can work around the issue?
$Web = New-Object System.Net.WebClient
Function Get-INIContent ($ContentList){
$INI = @()
Switch -regex ($contentList)
"^\[(.+)\]"
[string]$Section = $Matches[1]
$INI[$Section] = @{}
$CommentCount = 0
$ContentList = $Web.Downloadstring("http://download.nai.com/PRODUCTS/COMMONUPDATER/avvdat.ini")
Get-INIContent $contentlist
What I was hoping to do was search through the INI until I found the sections I want, and then read the fields for that section so I know what to download.  I won't be pulling all of the files, so I need to find a way to search for the sections I am
looking for then read all of the lines for that section and process them.

Found part of the problem... When I pull the file into a variable I lose the ability to search it line by line.  For example:
$Web = New-Object System.Net.WebClient
$ContentList = $Web.Downloadstring("http://download.nai.com/PRODUCTS/COMMONUPDATER/avvdat.ini")
#For some reason this returns the entire file
$contentlist | select -first 1
$contentlist | %{
#Thought this would be one line, but it is also
#the entire file...
$_
I have since shifted to a different method of reading the ini and I can process row by row...
$Web = New-Object System.Net.WebClient
$INILocation = "c:\SomeLocation\avvdat.ini"
$Web.DownloadFile("http://download.nai.com/PRODUCTS/COMMONUPDATER/avvdat.ini",$INILocation)
$INIFile = [System.IO.File]::OpenText($INILocation)
Do {
$CurrentLine = $INIFile.ReadLine()
#This is now one line like it should be.
$CurrentLine
While ($INIFile.EndOfStream -ne $True)
