There are ten web pages I want to deal with.
from http://www.af.shejis.com/new_lw/html/125926.shtml
to http://www.af.shejis.com/new_lw/html/125936.shtml
Each of them uses the charset of Chinese "gb2312", and firefox
displays all of them in the right form, that's readable Chinese.
My job is, I get every page and extract the html title of it and
dispaly the title on linux shell Termial.
And, my problem is, to some page, I get human readable title(that's in
Chinese), but to other pages, I got disordered word. Since each page
has the same charset, I don't know why I can't get every title in the
same way.
Here's my python code, get_title.py : -
#!/usr/bin/python
-
import urllib2
-
from BeautifulSoup import BeautifulSoup
-
-
min_page=125926
-
max_page=125936
-
-
def make_page_url(page_index):
-
return ur"".join([ur"http://www.af.shejis.com/new_lw/
-
html/",str(page_index),ur".shtml"])
-
-
def get_page_title(page_index):
-
url=make_page_url(page_index)
-
print "now getting: ", url
-
user_agent='Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'
-
headers={'User-Agent':user_agent}
-
req=urllib2.Request(url,None,headers)
-
response=urllib2.urlopen(req)
-
#print response.info()
-
page=response.read()
-
-
#extract tile by beautiful soup
-
soup=BeautifulSoup(page)
-
full_title=str(soup.html.head.title.string)
-
-
#title is in the format of "title --title"
-
#use this code to delete the "--" and the duplicate title
-
title=full_title[full_title.rfind('-')+1::]
-
-
return title
-
-
for i in xrange(min_page,max_page):
-
print get_page_title(i)
-
Will somebody please help me out? Thanks in advance. 3 1591

This pyparsing solution seems to extract what you were looking for,
but I don't know if this will render to Chinese or not.
-- Paul
from pyparsing import makeHTMLTags,Sk ipTo
import urllib
titleStart,titl eEnd = makeHTMLTags("t itle")
scanExpr = titleStart + SkipTo("- -",include=T rue) +
SkipTo(titleEnd ).setResultsNam e("titleChars ") + titleEnd
def extractTitle(ht mlSource):
titleSource = scanExpr.search String(htmlSour ce, maxMatches=1)[0]
return titleSource.tit leChars
for urlIndex in range(125926,12 5936+1):
url = "http://www.af.shejis.c om/new_lw/html/%d.shtml" % urlIndex
pg = urllib.urlopen( url)
html = pg.read()
pg.close()
print url,':',extract Title(html)

After looking at the pyparsing results, I think I see the problem with
your original code. You are selecting only the characters after the
rightmost "-" character, but you really want to select everything to
the right of "- -". In some of the titles, the encoded Chinese
includes a "-" character, so you are chopping off everything before
that.
Try changing your code to:
title=full_titl e.split("- -")[1]
I think then your original program will work.

Thank you, I tried again and I figured it out.
That's something with beautiful soup, I worked with it a year ago also
dealing with Chinese html pages and nothing error happened. I read the
old code and I find the difference. Change the page to unicode before
feeding to beautiful soup, then everything will be OK.

Hi,
I am using VB6 and want to extract text from a string. But ONLY take out
words that begin with 't' or 'd'. The mainstring is input by the user into
'txtMain' and then by clicking a command button, all the words that begin
with 't' or 'd' will be extracted and appear in a second text box,
txtExtract.
So, i know that I have to search through the main string for the character
"d", then extract the following characters until it...

I would be very grateful for any help with the following:
I currently have the code below. This opens a MS Word document, and
uses C#'s internal regular expressions library to find if there is a
match within this document. When I run the code I get a parser error
- I think there is an escape character in the Word doc format, or
perhaps trying to do a match with the entire document is not a good
idea.

Not sure if I'm posting this in the right spot, but....
Lets say i have a class for data access that gets instantiated on each page
in a web application ( .Net 1.1 )
From inside that class, how can I get a reference to the page that
instantiated it?
I'm assuming there is something in system.reflection, but I'm not familiar
with reflection enough to figure out what to use.

I have a program, That retrieves a webpage , such as a search engine
results page from the web, Then I need to go through the document and
retrieve just the search results. The problem is I want to omit the
sponsored results. So is there a way I can start analysing the
document at a specific point (ie after the sponsored results)

Let's suppose I have some nodes in an XML file, with an URL attribute:
<node url="mypage.php?name1=value1&foo=bar&foo2=bar2&name2=value0" />
<node url="myotherpage.php?name4=value4&foo=bar3&foo2=bar5&name2=value8" />
and so on.
Let's suppose I want to retrieve this @url parameter, BUT ONLY with the
values, in querystring, associated with "foo" and "foo2" (thus
discarding name1, name2, name4 and every other different ones).

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
