HTML tags optimization [ interesting problem]

[DENG]

hi all,

i use SGMLParser to process HTML files, in order to do some
optimizations,

something like this:

<i><b>TEXT1</b></i><b><i><u>TEXT 2</u></i></b>

optimise to

<i><b>TEXT1<u>T EXT2</u></b><i>


at the very beginning, i was thinking of analysing each text-block, to
know their color, size, if is bold or italic, but i found it was too
complicated.

e.g

<font color=red><font size=6>TEXT1</font></font>

optimise to

<font color=red size=6>TEXT1</font>


but if there is TEXT2 exist

<font color=red><font size=6>TEXT1</font>TEXT2</font>

we can not do any optimization.

my problem is I can not find a method to treat all those situation, I
had too much thinking and get fool now


anyone can give me some advices?

thanks




PS:

other examples:

1
<font size=5><font size=7>TEXT</font></font>
=>
<font size=7>TEXT</font>

2
<i>TEXT </i><i>TEXT</i>
=>
<i>TEXT TEXT</i>

3
<i>TEXT<i>TEX T</i></i>
=>
<i>TEXT</i>

etc...

Doesn't Tidy do this already ?

Whoever writes such a thing in 2005 ought to be shot down for the sake
of mankind !-)

You call this "optimized HTML" ? Even MS Word produces better code...

Tidy is open source AFAICT.

Re: HTML tags optimization [better learn CSS]

I know very well Tidy, sir

Tidy do a nice job but it is writen in Java, and have Python ported

my aim is to learn Python, learn how to program

I know many people write "hello the world" in 2005, why I can not write
this program in 2005?

you are french, right? peut etre we can talk about it in ecole
polytechnique? i'll be there waiting for you

thanks

Seems like we're not talking about the same program here. Tidy (aka
HTMLTidy) is written in C. You must be talking about it's Java port JTidy.

No one could have guess from your post, and I dont have psychic powers,
ok ?

From a professional POV, using existing tools that have proven to be
reliable is far better than reinventing the square wheel, hence my answer.

Peut-être pas, je ne mets jamais les pieds chez les polytechniciens .

I'm afraid you'll learn a looooong time.

Why not optimize it to:

<span class='onerole' >TEXT1</span>
<span class='secondro le'>TEXT2</span>?

If you're serious about using HTML, I suggest you read a book that's
not ten years old.

Re: HTML tags optimization [ interesting problem]

hi, Sybren,

thanks for your reply, if use CSS:

<span class=type1>tex t<span class=type2>tex t</span></span><span
class=type1>tex t</span>

optimise to:

<span class=type1>tex t<span class=type2>tex t</span>text</span>

what i need is the METHOD to do optimization, in fact, i have ready
write a program to analyse the syntax of CSS, to make it works with all
situation
