i found below at Drigg. there is no front3 there.  Is the engine wrong or something else.

front1=name="description"|name='description'|name=description
front2=content="|content='|content=
back1="
back2='
back3=\n

    if front1 and front2 both matched a string, how gsa handle this? in common, only one of front1 and front2 matched,right?

    front or front1,
    front2...
    Defines the content to cut in front of our 
    extract data. Separate multiple variations by |.

    back or back1, 
    back2,..
    Defines the content to cut in the back of our to
    extract data. Separate multiple variations by |.

    thanks,  but i said there is no front3

    front 3 isn't needed as they aren't dependend to each other.

    you may also use just but i think the first solution is the better one a Sven does it always like this ;)

    front=name="description"|name='description'|name=description|content="|content='|content=
    back="|'|\n

    thanks.
  • awintawint
    do you mean  two of the below are equal?

    front1=name="description"|name='description'|name=description
    front2=content="|content='|content=
    back1="
    back2='
    back3=\n


    front=name="description"|name='description'|name=description|content="|content='|content=
    back="|'|\n

  • awintawint
    if so, just | is enough,  1,2,3,4 etc do not needed just front and back is enough.

    No, thats not the same. It's like this...

    first front* is proceed...

    front1=p1|p2|p3|.. << first check if p1 exists...if not check for p2 than p3...

    front2=q1|q2|q3 <<< not if searches for q1 starting from the position found in front1.

    back1=\n << now check for a new line and when found cut it.

    back2=" << if found, it is cutting it

    back3=,|; << will check for , and if not found check for ; and cut.


  • awintawint
    got you. seem ozz misunderstand too.
    back* must be after front* right?
  • SvenSven www.GSA-Online.de
    yes...thats the thing it cuts of the extracted content. 
  • kaenekaene
    Would that be like (in regex):
    (name="description"|name='description'|name=description).*?(content="|content='|content=)(.*?)".*?'.*?\n
    If not, what would happen if it doesn't find back2 or back1? Wouldn't cut anything?
  • SvenSven www.GSA-Online.de
    The back parts are all proceed...back1 than back2 than back3...
  • awintawint
    support regex?
  • SvenSven www.GSA-Online.de
    no
  • kaenekaene
    so if any of the back parts isn't found then it fails to cut any string, right?
  • SvenSven www.GSA-Online.de
    No, back is applied when found...only all front's have to be present
