reading graph from a graphml file

reading graph from a graphml file

Good morning flare users,

hope life is pleasing yet challenging ;-)

This demo reads the graph from a graphml file. It implements for that purpose a simple GraphMLReader class which seems to do the job and might be of use for some beings around.

One strange problem I discovered is that the GraphMLConverter seems to have troubles if the graphml tag is written like

Code:

<graphml xmlns="http://graphml.graphdrawing.org/xmlns">

so for the time being I replaced it with

Code:

<graphml>

in the attached socialnet.xml file, on which this demo is based and which you need to download and place in the “execution” directory of your IDE in order to get this extremely mind blowing demo running

A GraphMLReader class would be of course a candidate for the flare lib, so please help with your feedback to make this first round attempt something mature.


Cheers

RE: reading graph from a graphml file

Hi Martin,

why is it not possible to load data from an external source f.e.

Code:

gmr.read("http://iaf-ma.de/_dennis24/Projektarbeit/casa_data.xml");

This won't work, nor uploaded on a server:
http://www.mightyx.de/GraphMLFileDemo/GraphMLFile.html

edit: just found the solution of this problem: A crossdomain.xml is needed on the target server (f.e. http://www.youtube.com/crossdomain.xml)

greets Dennis

Hey Martin,

I thought I would point out that the reason you can't access the first example is because you need to set the namespace in AS3:

Code:

namespace ns= "http://graphml.graphdrawing.org/xmlns";
use namespace ns;

You can learn more about namespace here:

RE: reading graph from a graphml file

How do you implement the ns namespace in a flex/ flash project?

RE: reading graph from a graphml file

Hi:

First I want to thank this forum because it is helping me a lot. I have a question:

I use this class for learn the flare layouts and create a radial tree, but my file I think that is big because with a simple graph file i can see the radial tree but with the attach file (graphfile.xml) I have this error:

#1502: El tiempo de ejecución del script ha superado el tiempo de espera predeterminado de 15 segundos.

The time execution is more than 15 seconds and i can't load de graph file. I use flex builder 3 with flare because i want to create a interface to see the visualization of the users with some charts. But if i can't load the file i can't start the project.......

thank's a lot.

RE: reading graph from a graphml file

Hi Prits,

do you have a proper crossdomain.xml on the target server? (see mightyx's reply above)
