Quick-n-ugly (and I do mean ugly) prettyprint into HTML -- if someone
wants to make it better:

from xml.sax import saxlib
from xml.sax import saxexts
import sys

class XMLPrettyPrint(saxlib.HandlerBase):
    """
    Pretty print an XML source tree in HTML with colors, etc
    """
    def __init__(self):
	totalstring=""

    def startElement(self, name, attrs):
	string= "<ul><font color=\"#1155ff\">&lt;"+name
	if attrs.getLength() > 0:
	    for key in attrs.keys():
		string=string+ " <font color=\"#339922\">"+key+"=\"<font \
color=\"#226600\">"+attrs[key]+"</font>\"</font>"  \
self.totalstring=self.totalstring+(string+"&gt;</font>")

    def characters(self, ch, start, length):
	self.totalstring=self.totalstring+"<ul>"+(ch[start:start+length])+"</ul>"

    def endElement(self, name):
	self.totalstring=self.totalstring+ "<font \
color=\"#1155ff\">&lt;/"+name+"&gt;</font></ul>"

    def startDocument(self):
	self.totalstring=self.totalstring+ "<tt>"

    def endDocument(self):
	self.totalstring=self.totalstring+ "</tt>"

    def processingInstruction(self, target, data):
	self.totalstring=self.totalstring+ "<font color=\"#ff2244\">&lt;?"+target+" \
"+data+"?&gt;</font>"


if __name__=="__main__":
    myparser=saxexts.make_parser()
    myxpp=XMLPrettyPrint()
    myparser.setDocumentHandler(myxpp)
    myparser.parseFile(sys.stdin)
    print myxpp.totalstring
