Re: [PLUG] sed newbie question

Re: [PLUG] sed newbie question

Keep in mind that most DOM parsers require syntactically correct
incoming HTML. That is "XHTML", not plain old sloppy HTML like most
Web pages still use. For example, tags must be properly nested, as:
<b><i>text</i></b>
not improperly as:
<b><i>text</b></i>
and no end tags can be missing, etc. May not work for most of
today's Web pages.

REs are very powerful but html can be quite complex and even irregular and REs are not the right tool to make a parser. While writing this I noticed that Sean suggested DOM manipulation with Python. Excellent idea. SED, BASH, etc. just don't have what you're going to need to create a reliable, effective solution. Good luck. Eric Michael Lazin wrote:

Yeah, it's just a proof of concept, obviously this is gonna take some
work. Out of curiosity is there a way to insert with sed, so you could
do something like inserting <!-- --> around the <iframe></iframe> tags? 
This might be better than removing a whole line of code.

No idea, but I can tell you how I would do it:
cat test.html | sed -e s/iframe//g
Keep in mind that with that specific regexp, you'll be left with
broken HTML code. I assume that's a proof of concept, though. :-)
Hope that helps,
