Re: SVGDocument - Difference when building my own or using autogenerated

[Tonny Kohar <to...@kiyut.com>]

Hi,

If the output can be parsed back by JSVGCanvas correctly, it seem that
your propietary XML output do things incorrectly. In your propietary XML
output, how do you print Text node? Make sure from the element, it get
the firstChild which is the text node, then print the Text Node.
