Beautifulsuop has been mentioned but its not part of standard python.

Her is an example of the standard library parser:

html = '''
Test page


Here is the first heading

A short paragraph
A second heading
A paragraph containing a
hyperlink to python

'''

from HTMLParser import HTMLParser

class H1Parser(HTMLParser):
def __init__(self):
HTMLParser.__init__(self)
self.h1_count = 0
self.isHeading = False

def handle_starttag(self,tag,attributes=None):
if tag == 'h1':
self.h1_count += 1
self.isHeading = True

def handle_endtag(self,tag):
if tag == 'h1':
self.isHeading = False

def handle_data(self,data):
if self.isHeading and self.h1_count == 2:
print "Second Header contained: ", data

parser = H1Parser()
parser.feed(html)
parser.close()

I'm not sure what you mean here? Do you mean fetching a file
from a remote server? There is an ftp module if its from an ftp 
site...

Re: [Tutor] html links

[Sönmez Kartal]

Hi,

import urllib
from BeautifulSoup import BeautifulSoup

page = urllib.urlopen(url) # url is the page address, if you are reading 
a file in your hard drive you could use just open(filename) too, and no 
needing to urllib
soup = BeautifulSoup(page)

#links = [str(link) for link in soup.findAll('a')]
links = soup.findAll('a')

I have used list compherension, comment outed line, because findAll 
function returns a different type specific to BeautifulSoup. First line, 
list compherension used converts every link to string.

Happy coding...

I believe BeautifulSoup could help with this, but am uncertain.

There are many ways to do this. The simplest would be:
filepath = raw_input("Where would you like to create the file? ")
And this can vary in difficulty; if you wanted, for example, a GUI that 
lets them
browse their directory tree graphically for the file they want, you 
could do that too.

Re: [Tutor] HTML links from Tkinter

[Alberto Troiano]

Thanks for the links
I will try both, the tktable and multilistbox

About the HTML llinks I will have to make some functions using webbrowser. I 
want to show some reports (tktable or multilistbox) but I want she to be 
able to check the same query on the web
So I think that with the GET method I can send paramaters to the page I want 
her to open

Best Regards

Alberto

On the Tkinter wiki there are some links to Tkinter table widgets (I have not 
tried any of these
though):

Quoting Alberto Troiano <[EMAIL PROTECTED]>:

If you want to open a web page in the user's default browser, check out the
webbrowser module in the standard library.

If you want to go to a website and suck down some data, you'll probably need
urllib (and it will be a bit more work).

There's no table widget in standard Tkinter.  Search in the Python Cookbook (on
ActiveState) for a MultiListbox; it might do what you need.
