visio 2003 export to xml

[martin]

is there some good article / sample of using the exported xml from visio
2003 document?

i want to be able to iterate elements and lines inside the exported xml.

and disaply as an image (third party image generation tools is not what i'm
searching for here)

i need also to iterate the lines in order to combine it into the final
image.

thanks for your support.
