Re: stripping white space?

This sounds like that could be done in PHP - but it would be an AWFUL lot of work and fiddle to get right. I personally wouldn't even consider it unless you had way to hook in to the final output of PHP. Possibilities ( not all of them sane ): * Modify PHP. Add an INI var for turning the feature on and off which

    defaults to off.

* Persuade someone at Zend to modify PHP so that a filter function can

    be specified which all output text is passed through - would have the
    same restrictions as the "header" function

* Call PHP from within PHP or Perl - call the original script directly

    using the PHP binary and then parse the text output to create munged
    HTML. ( Horribly inefficient )

* Wait until Apache 2.0 allows you to chain outputs. Regs Brian White At 22:39 9/07/2001 -0700, Kurt Lieber wrote:

Well, you can simply look for a closing bracket (>) followed by only white space characters (space, tab, return) followed by an open bracket (<) and, if there's a match, strip out the white space in between them. That would turn: <tr>

    <td>

into just <tr><td> You'd have to check for a bit more, such as <pre> and <code> tags, but it's not an unreasonable regex to write. What I am more concerned about is; I'm assuming everything would have to be encased within <?php ?> tags, meaning all HTML would have to be properly escaped, etc. *that* would be a major pain, so I hope I'm overlooking something. --kurt ----- Original Message ----- From: "Chris Lambert - WhiteCrown Networks" <chris@whitecrown.net> To: "Kurt Lieber" <php@internalcombustion.com> Sent: Monday, July 09, 2001 10:11 PM Subject: Re: [PHP] stripping white space? Nothing can _easily_ do this, as HTML puts formatting and content on the same page. You can strip new lines, you can strip tabs, and you can strip consecutive spaces, but there's no way to tell "<tr> <td>" from "Hello World!" /* Chris Lambert, CTO - chris@whitecrown.net WhiteCrown Networks - More Than White Hats Web Application Security - www.whitecrown.net */ ----- Original Message ----- From: Kurt Lieber <php@internalcombustion.com> To: <mukulsabharwal@yahoo.com>; <php-general@lists.php.net> Sent: Tuesday, July 10, 2001 1:14 AM Subject: Re: [PHP] stripping white space? | nope -- I want to completely suppress any extraneous white space characters | (tabs, spaces, etc.) in the HTML as it's being delivered to the client.
