"Sax" is an XML parser that operates element by element, line by line.

MiniDom sucks up an entire XML file, holds it in memory, and lets you work with it. Sax, on the other hand, emits events as it goes step by step through the file.


   1 import xml.sax
   3 class InkscapeSvgHandler(xml.sax.ContentHandler):
   4     def startElement(self, name, attrs):
   5         if name == "svg":
   6             for (k,v) in attrs.items():
   7                 print k + " " + v
   9 parser = xml.sax.make_parser()
  10 parser.setContentHandler(InkscapeSvgHandler())
  11 parser.parse(open("svg.xml","r"))
