    Regex problem

    Hello there,

    I have the following problem:
    I have a big html and i want to remove from it everything between some
    tags and to keep the rest, of course using regex, but any solution
    will be great.
    The number and type of tags may vary. Here is an example:

    <body>
    text text text text text text text
    text text text
    text text text text

    <remove1>
    text text text text text text
    text text
    text
    text text text
    </remove1>

    text text text
    text text

    <remove1>
    text text text text
    </remove1>

    text text
    text text
    text text text

    <remove2>
    text text text text text
    text text text
    text text
    </remove2>

    text text text text text
    text text text text
    </body>

    Any suggestions will be appreciated !
    Thanks.

      regex search and replace with <(/?[^\>]+)and "" leaves just your text text
      text etc

      Possible some flavours may need escaping: \<(/?[^\>]+)\>

              Sorry, didn't read your post carefully enough. As no other response,
              perhaps this may help:

              Similar to your original:

              <body>
              text text text text text text text
              text text text
              text text text text

              <remove1>
              text text text text text text
              text text
              text
              text text text
              </remove1>

              text text text
              text text

              <anotherremove1 >
              text text text text
              </anotherremove1>

              text text
              text text
              text text text

              <remove2>
              text text text text text
              text text text
              text text
              </remove2>

              text text text text text
              text text text text
              </body>

              Processing this with basically:

              (?<=<[ra])(.+\s)+|<[ra]

              eg: php processing the file with
              $RegStr = '/(?<=<[ra])(.+\s)+|<[ra]/mi';
              $OutStr = preg_replace($R egStr,"",$TstSt r);
              with $TstStr containing the file contents.

              will do what you (I think!) want.
              Outputs

              <body>
              text text text text text text text
              text text text
              text text text text


              text text text
              text text


              text text
              text text
              text text text


              text text text text text
              text text text text
              </body>


              You will need to define the contents of the [ ] enough to identify the
              tags and contents you want to remove. Don't know whether this is the best
              (simplest?) way to achieve what you want.

              If you process the file with a regex search and replace, it will need a
              positive look behind assertion capability.
