Let's look at the code to create a Pandas DataFrame using lxml: Like before, we'll create a DataFrame using the data list, and transpose the DataFrame. Now we can loop through the children elements of the root node and write them into a Python list.
To get the root element, we will use getroot() on the parsed XML data. We can directly use objectify.parse() and give it the path to XML file. Unlike ElementTree, we don't read the file data and parse it.

As this is a third-party module, you'll need to install it with pip like this: $ pip install lxml It also extends the native ElementTree module. The lxml library is a Python binding for the C libraries libxml2 and libxslt.

Then we write this data into a DataFrame. Meanwhile, writing child tags for the DataFrame column. We will loop across each child and sub child maintaining a list of data they contain. In this approach, we read the file content in a variable and use ET.XML() to parse the XML document from the string constant. We can move across the document using nodes which are elements and sub-elements of the XML file. ElementTree represents the XML document as a tree. It provides functionality for parsing and creating XML documents. Let's have a look at a few ways to read XML data and put it in a Pandas DataFrame.įor this section, we'll use one set of input data for every script. We'll also take data from a Pandas DataFrame and write it to an XML file. In this article, we will take a look at how we can use other modules to read data from an XML file, and load it into a Pandas DataFrame. However, Pandas does not include any methods to read and write XML files. The Pandas data analysis library provides functions to read/write data for most of the file types.įor example, it includes read_csv() and to_csv() for interacting with CSV files. XML (Extensible Markup Language) is a markup language used to store structured data.
