Practice Scenario: Some fields on a webpage are of interest to us, and we want to extract them and do other things. However, these fields may be in different places on a Web page. For example, we need to be on the Baidu page-contact us and pick up all the mailboxes.

Idea Split:

1. First, you need to get the source content of the current page, just like, open a page, right-view the page source code.

2. Find out the rules and use regular expressions to extract the matching fields and store them in a dictionary or list.

3. Cycle through the contents of a dictionary or list, implemented in Python with a for statement.

Technical aspects to achieve the relevant methods:

1. View the source code of the page, in selenium Driver.page_source this method gets

2. Using regular in Python, you need to import the RE module

3. For e-mail in emails:

Print Email

1 #Coding=utf-82   3  fromSeleniumImportWebdriver4 ImportRe5   6Driver =Webdriver. Chrome ()7 Driver.maximize_window ()8Driver.implicitly_wait (6)  9   TenDriver.get ("http://home.baidu.com/contact.html")   One #get the page source code ADoc =Driver.page_source -Emails = Re.findall (r'[\w][email protected][\w\.-]+', Doc)#use Regular, find [email protected] field, save to emails list - #loop Print matching mailboxes the  forEmailinchemails: -     Print(email)

Explain:

In the python regular expression syntax, thestring in Python is preceded by R for the native string, and the \w is used to denote the matching alphanumeric and underscore. The FindAll method under the RE module returns a list of matching substrings.
