Here, we want to find all item grand-children of channel children of the root(denoted by ‘.’) element. channel/item is actually XPath syntax (XPath is a language for addressing parts of an XML document). Now, once you have taken a look at the structure of your XML file, you will notice that we are interested only in item element. for item in root.findall('./channel/item'): Getroot() function return the root of tree as an Element object. Here, we create an ElementTree object by parsing the passed xmlfile. Ok, so let’s go through the parseXML() function now: tree = ET.parse(xmlfile) Interactions with a single XML element and its sub-elements are done on the Element level. Interactions with the whole document (reading and writing to/from files) are usually done on the ElementTree level. Element Tree has two classes for this purpose – ElementTree represents the whole XMLĭocument as a tree, and Element represents a single node in this tree. Here, we are using (call it ET, in short) module. We know that XML is an inherently hierarchical data format, and the most natural way to represent it is with a tree. We have created parseXML() function to parse XML file. The content of response now contains the XML file data which we save as topnewsfeed.xml in our local directory.įor more insight on how requests module works, follow this article: Here, we first created a HTTP response object by sending an HTTP request to the URL of the RSS feed. # creating HTTP response object from given url Loading and saving RSS feed def loadRSS():.

The UkParser child class redefines (or overrides) the phone_pattern class attribute. The phone() method in the Parser class uses the phone_pattern to extract a phone number. In this example, the Parser has a class variable phone_pattern.
