I trying to access the ca1 text. I am using etree but I cannot access it. I'm using below code.

import xml.etree.ElementTree as ET
tree = ET.parse('mca.xml')
root = tree.getroot()

def getElementsData(xpath):
    elements = list()
    if root.findall(xpath):
        for elem in root.findall(xpath):
            elements.append(elem.text)
        return elements
    else:
        raise SystemExit("Invalid xpath provided")



t = getElementsData('.//ca1')
for i in t:
    print(i)

I tried in different way to access it I don't know the exact problem. Is it recording file type issue?


ElementTree: Working with Namespaces and Qualified Names, ElementTree module implements a simple and efficient API for parsing and If the XML input has namespaces, tags and attributes with prefixes in the form  Python XML Parsing Python XML Parsing – We shall learn to parse xml documents in python programming language. There are many options available out there. We shall go through enough example for the following libraries ElementTree cElementTree minidom objectify We shall look into examples to parse the xml file, extract attributes, extract elements, etc. for all of the above libraries.


How about traversing like this

import xml.etree.ElementTree
e = xml.etree.ElementTree.parse('test.xml').getroot()
data = e.getchildren()[0].getchildren()[0].getchildren()[0].getchildren()[0].getchildren()[0].text
print(data)

xml.etree.ElementTree — The ElementTree XML API, Parsing XML with Namespaces¶. If the XML input has namespaces, tags and attributes with prefixes in the form prefix:sometag get expanded to {  The XML tree structure makes navigation, modification, and removal relatively simple programmatically. 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.


Try the following xpath

tree.xpath('//ca1//text()')[0].strip()

19.7. xml.etree.ElementTree — The ElementTree XML API, In the last two articles I've discussed namespace handling in Python 2.3's parser.namespaces) print "Attribute namespace:", repr(ns) print  You can check it out here. Our goal is to process this RSS feed (or XML file) and save it in some other format for future use. Python Module used: This article will focus on using inbuilt xml module in python for parsing XML and the main focus will be on the ElementTree XML API of this module.

Namespaces; The E-factory; ElementPath. How to Parse XML using minidom. We have created a sample XML file that we are going to parse. Step 1) Inside file, we can see first name, last name, home and the area of expertise (SQL, Python, Testing and Business) Step 2) Once we have parsed the document, we will print out the "node name" of the root of the document and the "firstchild tagname".


The lxml.etree Tutorial, XML can be parsed into an element structure using Parse XML keyword. The XML to be It also preserves the doctype and possible namespace prefixes saving XML. A Python dictionary containing attributes of the element. The xml.etree.ElementTree module implements a simple and efficient API for parsing and creating XML data. Changed in version 3.3: This module will use a fast implementation whenever available. The xml.etree.cElementTree module is deprecated. The xml.etree.ElementTree module is not secure against maliciously constructed data. If you need to


Parsing XML, I have imported a SVG file using the BeautifulSoup XML parser in order to in my code (tested in the interactive python shell). It seems like there is a bug with the XML parser which appends a colon to the xmlns-attribute for  Parsing XML with Namespaces¶. If the XML input has namespaces, tags and attributes with prefixes in the form prefix:sometag get expanded to {uri}sometag where the prefix is replaced by the full URI.
