[RESOLVED] Regular expresion to <script ...

saidbakr

Hi,

I need a regular expresion that match any string pattern start with <script or <#script and ended with </script> or </#script#>

Where # equals any number of white spaces.
Between the start and the end any characters or any numbers or any new lines may be found.

Assuming preg_ functions:

'#<\s*script.*</\s*script\s*>#Uis'

When testing this in my regex engine http://regex.larsolavtorvik.com/ it doesn't support the new lines saidbakr required.

Adding ungreedy and dot all solve the problem.

/<[ ]*script.*<\/[ ]*script[ ]*>/isU

The example test I tested with was:

<script ending with </script>
and
< script > testing
regex </ script    >

Or just use the regex I suggested above, with the added benefit that any white-space character will be matched (using the "\s" white-space character type). 🙂

I agree there is benefits using the \s instead of just blank space. It is easier to read and it takes any whitespace character. I must admit I didn't notice there where two answers when I had my first reply :-) But NogDog I tested your regex on my validator and noticed an error in it. You where missing a escape tag in the script end tag. It should have been :

/<\s*script.*<\/\s*script\s*>/isU

Hi,

Thank you all. I needed this regex to overcome the limitation of strip_tags() function. It removes <script> tag but it does not remove the code inside the tag.
Thank you for your valuable help!

I used "#" as my regex delimiter, and thus it was not necessary to escape the "/" (and this is why I opted to use the "#" as the delimiter).
