[james28909]: i am manually parsing html, and am trying to wrap my head around keeping up with tag counts
[james28909]: i can extract a certain tree manually by regexing the html file for a starting anchor, then i send the position of the match to a sub and then seek to that position in the file and keep up with div tags (for now)
[james28909]: how can i manage multiple tags? other than div?
[james28909]: i count the div and /div and when count == 0 it means i have got that nested tree
