[REBOL] Re: Parsing optional tags
From: lmecir:mbox:vol:cz at: 5-Nov-2001 0:35
Hi Geza,
it doesn't have to be so complicated, my version probably checks more things
than you needed (check if the tags are balanced etc.). There obviously is a
simpler way how to do this.
Hello Ladislav,
> i-tag: [copy collect to </i> </i>]
> not-i-tag: [copy collect to </b>]
> b-tag: [[<i> (following: i-tag) | (following: not-i-tag)] following
(append
> collects collect) </b>]
> htmlrule: [[thru <b> (follow: [b-tag htmlrule]) | to end (follow: [none])]
> follow]
> parse html htmlrule
Thank you for the working version but I just can't believe it has to
be so complicated - building a (in a way) complete syntax to strip off
two lousy HTML-tags ... :-(
If this is the more-or-less only "obvious" way to do it in the REBOL
parse dialect, I'll better stick to the old-fashioned way and build a
regex and feed it through sed/awk/vim or something like that.
