You write a crawler script using scruping hub, and they will run through there IP proxies and take care of the technical problems of crawling.
Crawlera is now the Smart proxy manager 
The DOMXPath class is a convenient and popular means to parse HTML content with XPath.

No, now there are handy tools for website change monitoring. We’ve evaluated some tools and would like to recommend the most useful ones that will make your monitoring job easy. Those tools nicely complement the web scraping software, service and plugins.
XPath is a formal language that is used to navigate through and query elements and attributes in XML documents. While this notation is being used in XSL and XQuery, it is very useful for DOM data access and extraction. XML documents and also HTML/XHTML documents are objects of DOM parsing while using XPath.
Recently, I was challenged to do bulk submits through an authenticated form. The website required a login. While there are plenty of examples of how to use POST and GET in Python, I want to share with you how I handled the session along with a cookie and authenticity token (CSRF-like protection).
In the post, we are going to cover the crucial techniques needed in the scripting web scraping:
