That's what I ended up doing.

That's what I was thinking.
I'll stay away from a named file.

All my best,

You may look at

URL:http://www.dieter.handshake.de/pyprojects/zope/CatalogSupport.html

It does the same as you want to do, but without the "formatter".

Alternatively, you may try a "StringIO" instance as a file object.

Finally, I can use files in external methods.
You should, however, be careful as several threads can execute
the same external method concurrently. Therefore, your
files are better not global.

[Zope] Fighting htmllib in external method

2000-10-10 Thread Jason Spisak 

Jonothan Farr,

Thanks very much!  I am new to Python.  I coded my first Zope app in
entirely DTML, so now I'm moving deeper.  That's a handy thing to have.

All my best,

Re: [Zope] Fighting htmllib in external method

Try using a StringIO object as your file.

import htmllib
import formatter
from cStringIO import StringIO

def index(self, html):
file = StringIO()
fmtr = formatter.AbstractFormatter(formatter.DumbWriter(file))
p = htmllib.HTMLParser(fmtr)
p.feed(html)
file.seek(0)
return file.read()

[Zope] Fighting htmllib in external method

2000-10-10 Thread Jason Spisak 

Howdy Zopsters,

I want to catalog some html files but I want to strip the html tags out.
htmlparser does a good job of that, but when I try to acces that from an
external method, I run into trouble.

import htmllib
import formatter

def index(self, html):
fmtr = formatter.AbstractFormatter(formatter.DumbWriter(file))
p = htmllib.HTMLParser(fmtr)
return p.feed(html)

Since the DumbWriter uses stdout, this returns None.  When I try to write
to a temporary file, or pipe I get 'bad file descriptor' errors because of
the way external method function I guess.  Any help would really be
appreciated.

All my best,
