I am a researcher and I need to download many ( or all) the Egyptian dialect pages in Wikipedia?
I am totally new to this. any help please
You are searching for the Wikipedia Database Dumps. The information about this dumps are reported in the Database Dumps Page, and an HTML version of the site is usually available in the HTML static Dumps.
As you correctly pointed out, the Egyptian Arabic (arz in ISO 639-3) language is not available in the Static HTML repository, but the database is available at the following official mirror (as reported in Database Dump Page) as SQL database. The schema for the database should be compatible with the common Wikipedia schema, which is described here.
I suggest you to carefully read this page, which provides additional information about the initialization of the database itself for local use and also suggests to never user web crawlers on the public Wikipedia sites. The same pages contains some script to parse and query the database.
There is an alternative. You may try to use resources such as dbpedia.org, which declares some dumps for arz language and can be queried with sql queries directly.
Happy Download!
