If you are only looking to batch process SVG files without rendering, you can just use any XML library. QDomDocument is perfectly fine for most situations. You can do something like setting a Title tag on the group or path that represents the icon, you can do this in inkscape via the 'object properties' dialog, and it will add that value as <title>text</title> as a child of the XML element represent <g /> or <path />.
The tricky bit about the SVG spec is getting the rendering right, but as long as you're not doing that, just use your favourite XML library. -- Wolthera
