printing indented html code

#1 July 19th, 2005, 03:27 AM

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>foobar</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(HTMLParser):

def __init__(self, out):
HTMLParser.__init__(self)
self.out = out
self.indent_level = 0

def write_line(self, text):
print >> self.out, '\t' * self.indent_level + 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_level += 1

def handle_endtag(self, tag):
self.indent_level -= 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.stdout)
i.feed('<html><head>foobar</head><body color=0>body</body></html>')
i.close()

- kv

Looks good. I'll give it a try.
