    printing indented html code

    Is there a module or library anyone knows of that will print html code
    indented? What I'd like would be for a function or class which works
    like this:

    htmlIndent(sys. stdout, '<html><head>fo obar</head>...')

    and will print somethinkg like this to stdout:

    <html>
    <head>
    foobar
    </head>
    ...

    My current way of doing this kind of stuff is less than ideal and will
    write such a function if it doesn't exist.

    Thanks,
    Lowell

      There are lots of HTML pretty printers around, but for starters take a
      look at this: http://www.oreilly.com/catalog/pytho...pter/ch05.html

          Thanks. At a glance, that looks like it's what I'm looking for.

              Depends on whether you have to deal with xhtml, valid html or just
              any, possibly invalid, "pseudo-html" that abounds on the net.

              Here's an example of (too) simple html processing using standard
              HTMLParser module:

              from HTMLParser import HTMLParser

              class Indenter(HTMLPa rser):

              def __init__(self, out):
              HTMLParser.__in it__(self)
              self.out = out
              self.indent_lev el = 0

              def write_line(self , text):
              print >> self.out, '\t' * self.indent_lev el + text

              def handle_starttag (self, tag, attrs):
              self.write_line (
              '<%s %s>' % (tag, ' '.join('%s=%s' % (k, v) for k, v in attrs))
              )
              self.indent_lev el += 1

              def handle_endtag(s elf, tag):
              self.indent_lev el -= 1
              self.write_line ('</%s>' % tag)

              handle_data = write_line

              # handle everything else...
              # http://docs.python.org/lib/module-HTMLParser.html

              if __name__ == '__main__':
              import sys
              i = Indenter(sys.st dout)
              i.feed('<html>< head>foobar</head><body color=0>body</body></html>')
              i.close()

              - kv

                  Looks good. I'll give it a try.
