I've been trying to get the value of the ci-name element whose sibling RandomAttribute's value(text) is IMPORTANT. I'm a beginner to python and I'm trying using Python's inbuilt ElementTree.

Here's the sample XML:

    <s-name>State 1</s-name>
        <d-name>District 1</d-name>
            <ci-name>City 1</ci-name>
            <RandomAttribute>UN- IMPORTANT</RandomAttribute>
            <ci-name>City 2</ci-name>
            <RandomAttribute>NOT SO IMPORTANT</RandomAttribute>
            <ci-name>City 3</ci-name>

Please help me out with this.

You can access the value with the XPath-1.0 expression


Just put this into a Python XML processor. In lxml this can look like

xml = ...
tree = etree.parse(xml)
result = tree.xpath('/state/district/city[RandomAttribute='IMPORTANT']/ci-name')

Output should be

City 3

20.5. xml.etree.ElementTree — The ElementTree XML API — Python , ElementTree module implements a simple and efficient API for parsing and creating XML Interactions with a single XML element and its sub-elements are done on the Element.find() finds the first child with a particular tag, and Element .text� Python has a built in library, ElementTree, that has functions to read and manipulate XMLs (and other similarly structured files). First, import ElementTree. It's a common practice to use the alias of ET: import xml.etree.ElementTree as ET Parsing XML Data. In the XML file provided, there is a basic collection of movies described.

Not a solution in one line like the previous one, but I like to keep track of how the XML is structured.

Maybe this helps you understand how ElementTree works?

import xml.etree.ElementTree as ET

xml = 'temp.xml'
xmltree = ET.parse(xml)
cities = xmltree.findall('district')[0].findall('city')
for city in cities:
    RandAttribute = city.findall('RandomAttribute')[0].text
    if RandAttribute == "IMPORTANT":
        ci_name = city.findall('ci-name')[0].text

19.11. xml.etree.ElementTree — The ElementTree XML API , Parses an XML section into an element tree incrementally, and reports what's going objects returned by Element or SubElement have the following methods and the attrib value is always a real mutable Python dictionary, an ElementTree � Tag: python,xml,python-2.7,xml-parsing When i parse it using ElementTree and save it to a file i Displaying a 32-bit image with NaN values (ImageJ) python,

import lxml.etree as etree

if xml you are taking about is string then

xml_xpath = "/state/district/city[RandomAttribute='IMPORTANT']/ci-name/text()"
XML_dom = etree.XML(xml)
XML_XPATH_name = etree.XPath(xml_xpath)
return XML_XPATH_name(XML_dom)

Most Pythonic way to find the sibling of an element in XML, You can use xpath: //*[@class='p_cat_heading'][contains(text(),'DEFINITION')]/ following-sibling::*[1]. Or you can use lxml: from lxml import html. An ElementTree will only contain processing instruction nodes if they have been inserted into to the tree using one of the Element methods. xml.etree.ElementTree.register_namespace (prefix, uri) ¶ Registers a namespace prefix. The registry is global, and any existing mapping for either the given prefix or the namespace URI will be removed.

The Extensible Markup Language (XML) is a markup language much like HTML. It is a portable and it is useful for handling small to medium amounts of data without using any SQL database. Python's standard library contains xml package. This package has ElementTree module.

Contents. lxml.etree; Other Element APIs; Trees and Documents; Iteration; Error Note, however, that it did not exist before version 1.0, so you will get an� Python contains several interfaces for processing XML data. In this post, we will discuss how to use the ‘ElementTree’ module in the python ‘xml’ library to parse XML data and store the data in a Pandas data frame. Let’s get started! For our purposes we will be using a sample ‘xml’ file, ‘books.xml’ ,which can be found here

Elements and Element Trees, from xml.etree import ElementTree. tree = ElementTree.parse("sample.xml") root = tree.getroot() children = root.getchildren() for child in children:� This is pretty close to the original and is certainly valid XML, but it’s not quite the same. However, it’s close enough. Let’s take a moment to review the code and make sure we understand it. First we create the root element by using ElementTree’s Element function. Then we create an appointment element and append it to the root.
