# How to get specific nodes in xml file in Python?

PythonServer Side ProgrammingProgramming

Using the xml library you can get any node you want from the xml file. But for extracting a given node, you'd need to know how to use xpath to get it. You can learn more about XPath here:https://www.w3schools.com/xml/xml_xpath.asp.

## Example

For example, assume you have a xml file with following structure,

<bookstore>
<book category="cooking">
<title lang="en">Everyday Italian</title>
<year>2005</year>
<price>30.00</price>
</book>
<book category="children">
<title lang="en">Harry Potter</title>
<author>J K. Rowling</author>
<year>2005</year>
<price>29.99</price>
</book>
</bookstore>

And you want to extract all title nodes with lang attribute en, then you'd have the code −

from xml.etree.ElementTree import ElementTree
tree = ElementTree()
root = tree.parse("my_file.xml")
for node in root.findall("//title[@lang='en']"):
for type in node.getchildren():
print(type.text)
