Hi. I've got a small problem with parse trees... first off, I don't exactly know what it is.
I'm a newbie, in a way, but I've been bravely trying to learn my way through all the confusion out in the web and in books when what I read seems oddly similar to Chinese.
Nevertheless, I think I've managed quite some knowledge and, having been reforming my website every year to try and show exactly that, I've finally come to the validating tools only to find out that, if IE shows it is fine, it does not mean it's alright.
I don't have my site on-line yet (not the reshaped one, that is), but I've already got the basic HTML (everything except the content text) succesfully validated. Unfortunately, when I tried to validate my external CSS stylesheet it gave me this message:
To work as intended, your CSS style sheet needs a correct document parse tree. This means you should use valid HTML.
Now, I've glanced through the appointed wrong and right CSS, but I can't seem to understand what is wrong with it!
Some notes:
- I've based it off a book and then... carried on a bit.
- I know that the scrollbar code part isn't supposed to exist or something, but since it works with IE... who am I to complain about it?
- this is exactly what I have on the document (cenario.css).
- the notes are in Portuguese and relate to the 'body of the document', 'text and body', etc.

Parse trees are the Graphical representation of the grammar which filters out
the choice for replacement order of the Production rules.
e.g
for a production P->ABC
the parse tree would be P

Right I don't know who's validator you are using but may I suggest your try the one from the W3C at http://jigsaw.w3.org/css-validator/
Also validate your HTML with their validtor at http://validator.w3.org/
Some of the problems in your CSS
----------------------------------------------------------------------------------------------------------------------
<!-- CORPO DO DOCUMENTO -->
This is not a CSS commend this is an HTML comment and is wrong in a CSS file. In a CSS file it should be
/* CORPO DO DOCUMENTO */
----------------------------------------------------------------------------------------------------------------------
text-color: #ccccff;
text-color is not a style you mean
color: #ccccff;
----------------------------------------------------------------------------------------------------------------------
Defining your H2 style
H2, {
the comma is a mistake should be
H2 {
----------------------------------------------------------------------------------------------------------------------
overflow-y: scroll;
the is no style overflow-y, the style is overflow
overflow: scroll;
----------------------------------------------------------------------------------------------------------------------
Defining your image style
img.logotipo {
height: 15;
width: 15;
}
lengths must have units, this should be
img.logotipo {
height: 15px;
width: 15px;
}
----------------------------------------------------------------------------------------------------------------------
That covers most of your errors
Thank you for all your help and for the clear explanations you've provided me.
I'm considering adding this site to my links section since, for what I've seen, is one of the more helpfull I've browsed through (simple enough for those who are just starting and want to do a good job nevertheless), even if there are others very good.
Thank you, again,
TwinT, Teresa

Hey all,
I've been playing around with the parser module, and based on the
documentation I would expect all symbols in a parse tree to be part of
the grammar. For example, I find this line in the symbol module docs:

definitions of the names in the context of the language grammar.

I am trying to write a program that does a few things very fast

Hi,
I'm trying to parse an xml file into an array tree. From the PHP site
in the comments, I got this code. But it doesn't work for me. It's saying
that the passed variable is not an array or object in the call end($stack),
in the first function startElement(). Anyone know why that would be?
$stack is an array, as far as I can tell.
Thanks

Hi Guys,
I am trying to build a Parse Tree with the following grammar. I have
implemented my insertions using a standard binary tree inserting
algorithm. With the psuedocode below, can you guys provide any helpful
feedback to placing insert statements into building nodes of the tree.
Any suggestions on how to build the tree will be appreciated.
I hope to build the tree to look like that

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
