Do you mean the top-left X, Y and bottom-right X, Y of SVG Document thats visible on screen?
If yes all you need to do is read the viewBox values. Here is a little javascript code that does this.
function whatever()
{
var svgdoc = document.rootElement.getOwnerDocument(); //reference to entire document
var svgtag = svgdoc.getDocumentElement(); //reference to <svg ......> tag
var vBox = svgtag.getAttribute("viewBox"); //returns viewBox value as string
var vBoxArray = vBox.split(/ /); //splits string into array separated by space
var minX = parseInt(vBoxArray[0]);
var minY = parseInt(vBoxArray[1]);
var width = parseInt(vBoxArray[2]); //by adding width to minX you can get maxX
var height = parseInt(vBoxArray[3]); //by adding hegith to minY you can getmaxY
}
Hope this will help.

Hello,
I need to know the minimum and maximum coordinates of an SVG document or
in other words: what are the lowest and highest x and y values in a whole
document.
My only idea is to parse all the elements, get the coordinates and
calculate the
min and max values, but that seems very costly to me so how can I fetch
minX, minY,
maxX, maxY easier?
