[scilab-Users] recovering the text of a web page from internet

[Adrien Vogt-Schilb]

Hi

I don't understand.

I would download the text with wget to TMPDIR, then read with scilab (by 
"open "myfile.txt", i wxas suggesting to do this from scilab). This 
would use the harddrive as an intermediairy beetween wget and scilab.
Maybe you could use

unix_g

instead of unix. unix_g will capture the output of wget and return it to 
scilab directly

I wish i could post an example, but i don't have wget installed in my PC 
anymore
you may try something like:
a= unix_g("wget http://www.google.com/")

of course you still have to install wget, but that seems very reasonable 
to me.

(just to be sure: unix and unix_g are scilab commands)
