Inspect, Extract, or Navigate SVG Image Elements Programmatically using C#

extract-svg-info.cs

//Load a document from a file
string documentPath = Path.Combine(DataDir, "shapes.svg");
    
using (var document = new SVGDocument(documentPath))
{
    // Get the root svg element of the document
    var svg = document.DocumentElement;
    	
    // Find the first child element with a given tag name
    var g = svg.GetElementsByTagName("g").First() as SVGGElement;
    			
    var rect = g.FirstElementChild as SVGRectElement;
    
    Console.WriteLine("Height: {0}", rect.Height);// 90
    Console.WriteLine("Width: {0}", rect.Width); // 100
}

inspect-SVG.cs

// Load a document
string documentPath = Path.Combine(DataDir, "shapes.svg");
    
using (var document = new SVGDocument(documentPath))
{
    var element = document.DocumentElement;
    Console.WriteLine(element.TagName); // svg
        
    element = element.LastElementChild;
    Console.WriteLine(element.TagName); // g
    
    element = element.FirstElementChild;
    Console.WriteLine(element.TagName); // rect
}
