Pulling dbname from web.config using powershell - powershell

Question

Found one part of my answer here, Get dbname from multiple web.config files with powershell
But need it to recurse through the IIS Sites and all the Web Apps inside those 'Sites'. I have multiple IIS 'Sites' with multiple Web Apps in each 'Site' need to check each ones web.config file and pull the db used. Cant figure out how to recurse the code in the link above.
#Code from link above.
Import-Module WebAdministration
Get-WebApplication |
ForEach-Object {
$webConfigFile = [xml](Get-Content "$($_.PhysicalPath)\Web.config")
Write-Host "Web Application: $($_.path)"
foreach($connString in $webConfigFile.configuration.connectionStrings.add)
{
Write-Host "Connection String $($connString.name): $($connString.connectionString)"
$dbRegex = "((Initial\sCatalog)|((Database)))\s*=(?<ic>[a-z\s0-9]+?);"
$found = $connString.connectionString -match $dbRegex
if ($found)
{
Write-Host "Database: $($Matches["ic"])"
}
}
Write-Host " "
}
Would like this to output the database name of each web.config file for each IIS Site and for each Web App in the IIS Site. Currently this only looks at the first web app in a IIS Site, and doesnt look at any others in the IIS Site, also doenst look to see if the IIS Site's web.config has a connection string to a DB.

Here is the code for you, from your reference I have changed looping mechanism not the actual logic to get the db name.
Import-Module WebAdministration
Get-Website | % {
$AppList = Get-WebApplication -Site $_.Name
foreach ( $app in $AppList )
{
$app.PhysicalPath
$webConfigFile = [xml](Get-Content "$($app.PhysicalPath)\Web.config")
# NEED TO CHECK WEATHER THE $webConfigFile FILE EXIST OR NOT
Write-Host "Web Application: $($_.path)"
foreach($connString in $webConfigFile.configuration.connectionStrings.add)
{
Write-Host "Connection String $($connString.name): $($connString.connectionString)"
$dbRegex = "((Initial\sCatalog)|((Database)))\s*=(?<ic>[a-z\s0-9]+?);"
$found = $connString.connectionString -match $dbRegex
if ($found)
{
Write-Host "Database: $($Matches["ic"])"
}
}
} # END OF INNER FOR EACH LOOP
} # END OF OUTER FOR EACH LOOP
