soapbox

we craft regex match specific case, given html parsing , use case hints number of tags in there, you'd best off using dom or using product html agility (free)

however

consider following powershell example of universal regex. in example iterating on each matching text outside script tags. here apply string replacement each matched group. should noted break if inside script use string looks open or closed <script> tags.

(?:^|</script[^>]*>)(.*?)(?=<script\s|$)

example

$regex = '(?:^|</script[^>]*>)(.*?)(?=<script\s|$)' $string = 'i wanna match string contains<script src=value> > that; bla ; bla < this</script> match "bla" '  write-host start  write-host $string write-host write-host found $matches = @() ([regex]"(?i)$regex").matches($string) | foreach {     write-host "value @ $($_.groups[1].index) = '$($_.groups[1].value)'"     } # next match 

yields

start wanna match string contains<script src=value> > that; bla ; bla < this</script> match "bla"   found value @ 0 = 'i wanna match string contains' value @ 89 = ' match "bla" '
