Create an element, which will act as our root element. In our code we use the import command with the as keyword, which allows us to use a simplified name ET in this case for the module in the code.
In addition, the module has the function findwhich returns only the first sub-element that matches the specified criteria. The example below shows how to change the name of a node, change the name of an attribute and modify its value, and how to add an extra attribute to an element.
In addition, there is another helper function that returns the text of the first node that matches the given criterion: The function applies to the attrib object parameter.
In this article, the ElementTree module will be used in all examples, whereas minidom will also be demonstrated, but only for counting and reading XML documents. Thus, we can use the function getElementByTagName to find a specific tag. Using ElementTree, and like the previous code example, we obtain the node attributes and text using the objects related to each node.
The example below shows us how to use clear: Using ElementTree Similarly, the ElementTree module allows us to calculate the amount of nodes connected to a node.
It specifies the name of the attribute and sets it to None. The DOM is an application programming interface that treats XML as a tree structure, where each node in the tree is an object.
We have also used the minidom model to parse XML files. Attr and "DOM Text nodes".
In the example below, we have accessed the attributes and text of a specific node, and of all nodes together.
This function has the syntax: It returns all items with the specified condition. You may also notice that writing XML data in this way calling tree. In addition, the "seconditem" node has "name2" as an attribute, and its text is "seconditemabc", as expected.
The function returns a document, which can be handled as an XML type. This function returns an element to us, which can be used to attach other sub-elements, as we do in the following lines by passing items to the SubElement constructor.
The following example shows us how to use it: You may have noticed how accessing objects and attributes with ElementTree is a bit more Pythonic, as we mentioned before. The code below shows how to create an XML file with the same structure as the file we used in the previous examples.
In the last 3 lines of the code below we create a string out of the XML tree, and we write that data to a file we open.I'm using ElementTree in Python version to create an XML file with that information.
Code import sqlite3 How do I get Python's ElementTree to pretty print to an XML file? Ask Question. Whatever your XML string is, you can write it to the file of your choice by opening a file for writing and writing the string to the file. Modifying an XML File¶ ElementTree provides a simple way to build XML documents and write them to files.

Jinja can handle looping over a list of data to produce the inner xml of your document list.
That is a bit trickier with raw python string templates. For a Jinja example, see my answer to a similar question. Here is an example of generating your xml with string templates.
