web scraping to fill out (and retrieve) search forms? -

-

I was wondering whether to "automate" the task of typing in entries for finding forms and removing the results from the results possible . For example, I have a list of journal articles for which I want to get a DOI (Digital Object Identifier); For this manually I will go to the journal article search page (for example), type in the authors / title / volume (etc), and then find the article from the list of returned results, and select and paste the DOI. In the reference list, I regularly use R and Python for data analysis (I was inspired by a post on RQRL), but not much information about the Web protocol Is it possible ... Is it possible (for example, to use something like Python's beautiful soup?). Are there any good references to doing something remotely from this task? I am interested in learning about web scrapping and web scrapping as much as to accomplish this special task normally ... Thank you for your time!

Beautiful soup is great for parsing webpages - half of what you want to do is. Pyrens, Pearl, and Ruby have a version of MacKenize, and it is from the other half:

Mechanize that you control a browser: 

  # Follow a link browser. Follow_link (link_node) # Submit a form browser .select_form (name = "search") browser ["author"] = ["author # 1", "author # 2"] browser ["volume"] = "any" Search_response = br.submit ()

Firebug, Fastbug, is an excellent startup with a mechanical and beautiful soup, an extra tool used in this fast Ruby Scrapping Guide: / P>

Firebug can speed up your build of the xpath to save you some critical time.

Good luck!

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
