in reply to Extracting HTML content between the h tags

Something like this (just for first ps):

my @nodes = $p->findnodes('//h2[2]/preceding-sibling::p[preceding-sibl +ing::h2[1]]');

    Thank you a lot! I did not know this syntax.
    One more question if I dare :-)
    In about 10 pages the last h2-tag is missing, so that I used the following workaround:
    my @solution_2 = $content->findvalues( './h2[4]/preceding-sibling::*' +); unless ( @solution_2 ) { @solution_2 = $content->findvalues( '//hr/preceding-sibling::*' ); }
    I tried the same with your syntax as:
    @solution_2 = $content->findvalues( '//hr/preceding-sibling::p[precedi +ng-sibling::h2[3]]' );
    but I get an uninitialized value only.
    I understood the syntax so: "search the siblings but stop if the tag in brackets appears". Is this correct? If so, what am I doing false with the above attempt?
    Spasibo!
      According to your HTML preceding-sibling for hr will be div tag but not p tag... So this code will find all ps after last h2:
      $p->findnodes('//h2[4]/following-sibling::p');
      Or (more flexible):
      $p->findnodes('//h2[last()]/following-sibling::p');
        Thank you very much!
