Overview
This web driver is designed to save information from the Moroccan Legislature website as a pdf before the information is removed from the website due to lack of space.
On the right hand side of the website, the final bullet is a link to archived bills.
On the right hand side of the website, one bullet above the last header, is a link to links of all the proposed bills. When clicked, the user is directed to the most recent batch of links of proposed bills. The movement button on the bottom left in arabic means, "go to last page", and the second from the left means "previous page". When "go to last page" is clicked, the batch of links to proposed bills that are about to be removed from the website are listed with the oldest link at the bottom of the list.
When any proposed bill link is clicked, it opens up a page with information about the bill, and about discussions in parliament. There are up to two hyperlinks on this page, the first of which is a pdf of the original bill. If there is a second link further below, it contains a pdf of the Committee Report for the bill (if it was sent to a Committee).
The two pdfs, as well as the webpage of the proposed bill may be subject to record keeping.
Driving Opportunities
Five websites within the Moroccan Legislature site have data that needs to be recorded.
Moroccan Monarchy Proposed Bills
The data that needs to be extracted from this site includes the pdfs of all the bill pages, as well as any interior pdfs on each page. The bill pages should be named by their url, and the interior pdfs should be named by their respective bill numbers.
Moroccan House of Representatives Proposed Bills
See Monarchy proposed bills for instructions.
Moroccan Legislature Ratified Bills
See Monarchy proposed bills for instructions.
Moroccan Legislature Oral Questions
The embedded pdfs on this site are not useful. The useful data elements are the dates and questions listed on the main site. To get this data, I built a web crawler that scraped the date, question, and all relevant information about the question from the site. Then, I used Selenium to download pdfs of the questions.
Moroccan Legislature Written Questions
See Oral Questions section.

Web Crawler Code
I used a python library called Scrapy.
Once downloaded and installed properly, a new project is created by typing into the command line:
scrapy startproject projectname
This will create a project for you with all of the necessary components you need.
From this window, scrapy provides a helpful tool to test any web scraping lines of code you would like to try out. Enter:
scrapy shell 'webaddress'
From here, you can type selector statements and print them to see if your statements are getting the data you desire.
To actually build your webcrawler, open a new python script, and save it in the spiders folder that was created automatically for you under your projectname folder. Some example code for a spider is shown below; this was my spider for the oral questions portion of the Moroccan site.
import scrapy
import string
class MySpider(scrapy.Spider):
name = "oral"
page_range = 375
start_urls = (["http://www.chambredesrepresentants.ma/ar/%D9%85%D8%B1%D8%A7%D9%82%D8%A8%D8%A9-%D8%A7%D9%84%D8%B9%D9%85%D9%84-

Further Inquiries
Further inquiries have been requested for the Kuwait, Tunisian, and Algerian Parliaments. In addition, a way to link the downloaded pdfs to pertinent lines in the csv files would be very useful.
Kuwait Parliament
Data to download (Tables and PDF files): Monarchy - Proposed Bills (مشروع بقانون); For 13th and 14th terms. Parliament - Proposed Bills (اقتراح بقانون); for 14th term: Proposals (اقتراح بــرغــبـــة): For 13th term and 14th terms Meeting Agendas/Minutes (جدول اعمال الجلسه); for 14th term
UPDATE: Kuwait Bills Site
The site generates dynamic content. The desired pages for scraping are found by selecting the first option of the first dropdown menu, and hitting enter. """The website's URL never changes.""" The HTML of the site will change as objects are selected on the site. I used Selenium to interact with the elements on the page, and the .text method of Web Elements in Selenium to have Selenium act as a psuedo web crawler. The code is found in the following directory:
E:\McNair\Projects\Middle East Studies Web Drivers\Kuwait
The next step in the project requires the data found when selecting the links on each page. This data has specifics on each of the bills. The page appears as a dynamically generated frame which presents some issues. There is a close button on the window that is opened up that cannot be accessed from the interior frame, but also cannot be accessed from the original framework. I experimented with executing javascript code, and switching frames, but nothing worked. My workaround solution was to reload the page every time I opened up the interior frame. This is a separate script saved in the same directory listed above and titled kuwait_retrieve.py.
