The arguments tag and attrs are similar to the HTMLParser.handle_starttag(tag, attrs) method.
HTMLParser.handle_startendtag(tag, attrs) - As the name suggests, this method deals with the start end tags like.
Similar to the handle_starttag(tag,attrs) method, this also converts tag names to lowercase. For example, the method call for will be: handle_endtag(‘body’). Since there will be no content inside an end tag, this method takes only one argument which is the tag itself.
HTMLParser.handle_endtag(tag) - This method is pretty similar to the above method, except that this deals with only end tags like.
For example, in the tag the method call would be handle_starttag(‘meta’, ). If a tag has attributes they will be converted to a key, value pair tuple and added to the list. Note that the tag name was converted to lowercase and the contents of the tag were converted to key,value pairs. For example, for the tag the method call would be handle_starttag(‘meta’, ). The tag argument refers to the name of the start tag whereas the attrs refers to the content inside the start tag.
HTMLParser.handle_starttag(tag, attrs) - This method deals with the start tags only, like.
HTMLParser.reset() - This method resets the instance and all unprocessed data is lost.
HTMLParser.close() - This method is called to mark the end of the input feed to the HTML Parser.
Only after the data is fed using this method can other methods of the HTML Parser be called. It keeps processing data as it gets and waits for incomplete data to be buffered. This method accepts data in both unicode and string formats.
HTMLParser.feed(data) - It is through this method that the HTML Parser reads data.
To use the HTML Parser, you have to import this module: from html.parser import HTMLParser Methods in HTML Parser For this reason, HTML Parser is often used with urllib2. Note that to use HTML Parser, the web page must be fetched. This is a class that is defined with various methods that can be overridden to suit our requirements. HTML Parser, as the name suggests, simply parses a web page’s HTML/XHTML content and provides the information we are looking for. This is the source from which the HTML Parser scrapes content for NYTimes! What is HTML Parser? A new page opens containing a number of links, HTML tags, and content. Select View page source or simply press the keys Ctrl + u on your keyboard. Go to the website NYTimes and right click on the page. The next question is: where is this information extracted from? To answer this, let's use an example. This is only one example of many potential uses. For instance, it can be very helpful for quickly extracting all the links in a web page and checking for their validity. This is a very easy way to gather information. Python is one of the languages that is extensively used to scrape data from web pages.
Urllib2 (not mandatory but recommended).
