powershell - Swapping text in an HTML file -

-

i want update bit of text in html file. text in html file: 

<html><body>normal</body></html>

i want change normal rollout , vice versa. code @ first was

(get-content c:\temp\a.html) | foreach-object {$_ -replace "normal", "rollout"} | set-content c:\temp\a.html

this worked great, except want run same script change rollout normal. trying if else if's didn't work either. below 1 of many attempts using if..elseif:

$a = get-content c:\temp\a.html (get-content c:\temp\a.html) | if($a -match "normal") { foreach-object {$_ -replace "normal", "rollout"}  } | elseif($a -match "rollout") { foreach-object {$_ -replace "rollout", "normal"} } | set-content c:\temp\b.html

how can approach differently?

using [regex]::replace, script block delegate , substitution hash:

$replace = @{ normal = 'rollout' rollout = 'normal' }  $x = @( '<html><body>normal</body></html>' '<html><body>rollout</body></html>' )  $x | foreach { [regex]::replace( $_,'(normal|rollout)',{$replace[$args[0].value]} ) }  <html><body>rollout</body></html> <html><body>normal</body></html>

that toggle between "normal" , "rollout"
