Hi,

that sounds very interesting, the DOM inspector in Firefox seems to be  
able to walk the xml structure so I guess there's a means of  
accessing/modifying content with javaScript.

   One thing I've often wanted on working with SVG is a means to get a  
readable file at the end of a plot command without having to unset  
terminal to write out the xml terminators and close the file. Unless this  
is done the file seems to be unparsable to any readers I've tried.

For example , if I output to jpeg or png, I get a readable file after the  
plot command. With svg I dont.

Would it make sense to have gnuplot terminate the unmatched tags until a  
further command is given in either of the following cases:

1/ end of .gnu file input from load "filename" . If svg terminal is still  
open , close unmatched tags.
2/ interactive use after plot command close tags while awaiting further  
input.

The added tags would have to be stipped off again on adding further  
content.

What I'd like to get to is periodic replotting of volatile data whilst  
independantly refreshing / reloading the SVG output in the viewer,  
typically a web browser on a timed or manual refresh.

Especially in debugging it would be nice to avoid:  unset terminal ; set  
terminal svg; replot; unset terminal .... loops.

If I've just missed a trick, sorry for the noise.

regards, Peter.
