World: r3wp

7. financing / sponsoring: To be able to do it, one needs to have 
something to spend. And yes, making money form projects is the goal 
for us. This gives the freedom to spend money on non-project relasted 
R3 stuff we do. This is the sponsoring and investment we do into 
R3. As long as I can finance the sponsoring parts I will do it.


Again, I follow the golen rule: The one owning the gold makes the 
rules.


Meaning, I set the priorities to the things we need or which complete 
some aspects etc. But it won't be a community driven process.

All this won't stopp anyone to bite the bullet and do something on 
their own. If you want to avoid double work, cross-check with us. 
We will tell everyone what we are working on. I will tell everyone 
what our plans are. etc. As transparent as possible.

Again, we will move forward. You can "follow" us and use what we 
have done. You can "accompany" us to help driving things forward 
faster. At the end of the day it's your decision (of course).

But I won't enter any Kindergarten discussions that are not moving 
us forward or where some go nuts because we have clear red thread 
we follow and don't care to much what they think.

That's it. Overall, IMO we have moved R3 forward much faster and 
with greater progress than before. And it's not only because we are 
now coding everything etc. By far not. But at least we have helped 
to get more momentum to R3.

android is linux based ... i have one on my acer laptop that's a 
short linux ...

on acer the android don't have access to android market ...

instead of having an android phone maybe the devtools include an 
emulator no ?

Thanks Robert. I like the fact that a goal is the use of R3 to build 
commercial apps. That means things like accelerator keys and other 
features have a better chance of being seen as important.

cool... will be there any examples as well?

(OT: Our world is back online)

Carl, great news! I'm ready :-)

I have a XML file and want to handle it by tags like a nested block. 
Are there are any tricks? Or do I need to use PARSE / FIND etc.

So, you want to use path notation on the parse XML?

parsed XML

I would like to extract a set of elements like: Everything between 
<TAG> ... </TAG>

TAG should be specified.

What I mean is, do you want to convert the XML to a block and then 
access it like this?

  data/tag

Or do you just want to parse the raw data out of the XML between 
those two <tags>?

No, not necessary.

Yes, just raw data.

Just use PARSE then. I have a solution for the block approach, but 
just use PARSE when I need to extract data in more stream-oriented 
ways.

Give me a minute though, I might have something...

This was used with small pieces of XML, rather than entire documents, 
but might be a starting point for you.


xml-get-field: func [input name /local xml-field= data other-name] 
[
	xml-field=: compose/deep [ 
		some [

   (rejoin ["<" name ">"]) copy data to (rejoin ["</" name ">"]) to 
   end
			| skip ;(to paren! [prin '.])
		]
	]
	either parse input xml-field= [data] [none]
]

Ok, thanks.

I've used Gavin's XML-object.r in a couple of projects. Not tried 
it under R3 though:
   http://www.rebol.org/view-script.r?script=xml-object.r

http://www.rebol.it/power-mezz/parsers/ml-parser.html

inside?: no
parse-ml "...your text..." func [command data] [
    either inside? [
        ?? command ?? data
        if command = </tag> [inside?: no]
    ] [
        if command =  <tag> [inside?: yes]
    ]
]

; Another flavour of Rebol XML:
do http://www.ross-gill.com/r/r3xml.r
doc: load-xml/dom location
foreach tag doc/get-by-tag <a> [
	probe tag/flatten
	probe tag/text
	probe tag/get #href
]

Chris, you post can now be done native using DECODE. Carl added this 
yesterday.

I proposed a change to how path notation works on TAG! to return 
name value blocks for attributes.

Decode loads an XML document?

Is there docs on the change?

even better would be to release the binaries!

http://www.rebol.com/cgi-bin/blog.r?view=0484#comments

Does any one have write access, or is Carl mistaken ?

ie. anyone with a rank of 50 or higher

Here is how it works:

Added it as a codec so you can access it:

>> ml: decode 'markup read http://www.rebol.com
>> foreach tag ml [probe tag]
<!doctype html>
^/
<html>
<head>
^/
<meta name="generator" content="REBOL WIP Wiki"/>
^/
<meta name="date" content="10-Aug-2010/12:18:33-7:00"/>
^/
<meta name="rebol-version" content="2.100.97.4.2"/>
^/

<meta http-equiv="Content-Type" content="text/html;charset=UTF-8"/>

It's a simple way to traverse over tags.

No fancy thing yet.

btw - codecs were supposed to be redone, using port mechanism, to 
allow streaming etc. Is this the case already, or not?

Don't know. DECODE doesn't look like a port to me. Maybe on the lower 
level this is done via a port like mechanism.

Equivalent to load/markup then? With respect, that's not exactly 
the same as the example I posted...

Yes, that's the missing part I made a proposal for to Carl.

r3xml is an R3 port of AltXML, a Rebolised version of XML DOM: http://bit.ly/XMLandREBOL

2.100.99.3.1  the use of  function  at  with negative index simply 
returns the whole series - which reminds me to ask why   at   with 
index 0 doe not return the series atfter the last item i.e. place 
you at the end of the series?  The docs for  at   specify behavior 
for a negative index      "Using a negative index N, you can go N 
values backwards in a series:"   PS   I have relocated to Fredericton, 
NB, Canada.  Lovely, green and interesting.

Chris, with the hostkit you can compile in your own functions such 
as r3xml

... big typo at the top of the page!

G: I'm not clear on how to get to that point or how to do that.  
Or if it's worthwhile?
