Convertto-Html: Highlight the cells with special values?

Question

The following statement will generate a bit html table.

ps | convertto-html

I want to make the text (or the whole line) of \"CPU(s)\" in color

Answer 1

Sample I once made at a late night while playing around with Powershell (note : code is not optimized but it can be used as inspiration since it does exactly what you want). This sample was based on the Exchange CMDlets where I wanted to highlight mailboxes which were over XXX GB.

$MailboxStatisticsList = Get-Mailbox | Get-MailboxStatistics
$Report = foreach ($Mailbox in $MailboxStatisticsList)
    {
    $Split = $Mailbox.TotalItemSize.Split(" ")
    ## New way to get it right : we Regex the bytes and convert it to MB
    $MailboxItemSize = $($Split[2] -replace '[^0-9]') / 1MB
    [PSCustomObject] @{
        Mailbox = $Mailbox.DisplayName
        TotalItemSize = $MailboxItemSize -as [int]
        } ## END OF PSCUSTOMOBJECT
    } ## END OF FOREACH LOOP


$CSS = @'

'@

$BaseHTML = @'

## Convert to HTML and export table to a variable
$HTMLTable = $Report | Sort-Object TotalItemSize -Descending | ConvertTo-Html -Fragment
## Import the HTML table as XML
[xml]$XML = $HTMLTable
## Create the attribute Class....
$TableClass = $XML.CreateAttribute("class")
## ....and give it the value "test"
$TableClass.Value = "mailboxsizetable"
## Now we stick it together and append it
$XML.table.Attributes.Append($TableClass)
## Outputting $XML.OuterXML returns the HTML with the class

## Now we take it 1 step further : conditional formatting for the table rows (on individual  is on my ToDo list)
## Foreach TR :
foreach ($TableRow in $XML.table.SelectNodes("tr"))
    {
    ## each TR becomes a member of class "tablerow"
    $TableRow.SetAttribute("class","tablerow")
    ## If row has TD and TD[1] has the state running...
    if (($TableRow.td) -and ([int]$TableRow.td[1] -gt 2000))
        {
        ## tag the TD with the class "notrunning" (should make this an Id)
        $TableRow.SelectNodes("td")[1].SetAttribute("class","toobig")
        }
    }
## Added code : enclose the table in a div tag
$FinalHTMLTable = [string]::Format('
{0}
',$XML.OuterXml)
