For an HTML document, Cleaner is a better general solution to the problem than using strip_elements, because in cases like this you want to strip out more than just the tag you also want to get rid of things like onclick=function() attributes on other tags. root.Below is an example to do what you want. root.tag 'collection'Īt the top level, you see that this XML is rooted in the collection tag. Now that you have initialized the tree, you should look at the XML and print out values in order to understand how the tree is structured. tree = ET.parse('movies.xml') root = tree.getroot() The main goal in this tutorial will be to read and understand the file with Python - then fix the problems.įirst you need to read in the file with ElementTree. The only problem is the data is a mess! There have been a lot of different curators of this collection and everyone has their own way of entering data into the file. In the XML file provided, there is a basic collection of movies described. It's a common practice to use the alias of ET: import as ET Parsing XML Data Python has a built in library, ElementTree, that has functions to read and manipulate XMLs (and other similarly structured files).įirst, import ElementTree. ![]() The XML tree structure makes navigation, modification, and removal relatively simple programmatically.

Here’s a snapshot of movies.xml that we will be using for this tutorial: DVD 1981 PG 'Archaeologist and adventurer Indiana Jones is hired by the U.S. An XML attribute can only have a single value and each attribute can appear at most once on each element. Attributes are name–value pair that exist within a start-tag or empty-element tag.The largest, top-level element is called the root, which contains all other elements.Elements can contain markup, including other elements, which are called "child elements". The characters between the start-tag and end-tag, if there are any, are the element's content. A tag is a markup construct that begins with. XML documents have sections, called elements, defined by a beginning and an ending tag.We can also use XML as a standard format to exchange information. Extended from SGML (Standard Generalized Markup Language), it lets us describe the structure of the document. As a data scientist, you’ll find that understanding XML is powerful for both web-scraping and general practice in parsing a structured documentĮxtensible Markup Language (XML) is a markup language which encodes documents by defining a set of rules in both machine-readable and human-readable format. ![]() Learn how you can parse, explore, modify and populate XML files with the Python ElementTree package, for loops and XPath expressions. “shallow focus photography of spider web” by Robert Anasch on Unsplash
