There are lots of different ways to do it. HTML is just text so technically you don’t need anything special. Python has a built in library for reading CSV files then you just need to spit out an HTML representation of it. You could do it with for loops and string concatenation if you wanted to. It is used for extracting data from HTML files. Or we can say using it we can perform parsing HTML in Python. Installing BeautifulSoup4. Here I am using PyCharm. I recommend you using the same IDE. So open PyCharm, Go to file menu and click settings option; Click Project Interpreter and press the ‘+’ sign for adding the BeautifulSoup4 package.

What is XML?

XML stands for eXtensible Markup Language. It was designed to store and transport small to medium amounts of data and is widely used for sharing structured information.

Python enables you to parse and modify XML document. In order to parse XML document you need to have the entire XML document in memory. In this tutorial, we will see how we can use XML minidom class in Python to load and parse XML file.

In this tutorial, we will learn-

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'. Tagname and nodename are the standard properties of the XML file.

• Import the xml.dom.minidom module and declare file that has to be parsed (myxml.xml)
• This file carries some basic information about employee like first name, last name, home, expertise, etc.
• We use the parse function on the XML minidom to load and parse the XML file
• We have variable doc and doc gets the result of the parse function
• We want to print the nodename and child tagname from the file, so we declare it in print function
• Run the code- It prints out the nodename (#document) from the XML file and the first child tagname (employee) from the XML file

Note:

Nodename and child tagname are the standard names or properties of an XML dom. In case if you are not familiar with these type of naming conventions.

Step 3) We can also call the list of XML tags from the XML document and printed out. Here we printed out the set of skills like SQL, Python, Testing and Business.

• Declare the variable expertise, from which we going to extract all the expertise name employee is having
• Use the dom standard function called 'getElementsByTagName'
• This will get all the elements named skill
• Declare loop over each one of the skill tags
• Run the code- It will give list of four skills

How to Create XML Node

We can create a new attribute by using 'createElement' function and then append this new attribute or tag to the existing XML tags. We added a new tag 'BigData' in our XML file.

1. You have to code to add the new attribute (BigData) to the existing XML tag
2. Then you have to print out the XML tag with new attributes appended with existing XML tag

• To add a new XML and add it to the document, we use code 'doc.create elements'
• This code will create a new skill tag for our new attribute 'Big-data'
• Add this skill tag into the document first child (employee)
• Run the code- the new tag 'big data' will appear with the other list of expertise

How to Parse XML using ElementTree

ElementTree is an API for manipulating XML. ElementTree is the easy way to process XML files.

We are using the following XML document as the sample data:

Reading XML using ElementTree:

we must first import the xml.etree.ElementTree module.

Now let's fetch the root element:

Following is the complete code for reading above xml data output:

Summary:

Python enables you to parse the entire XML document at one go and not just one line at a time. In order to parse XML document you need to have the entire document in memory.

• To parse XML document
  • Import xml.dom.minidom
  • Use the function 'parse' to parse the document ( doc=xml.dom.minidom.parse (file name);
  • Call the list of XML tags from the XML document using code (=doc.getElementsByTagName( 'name of xml tags')

• • Use function 'createElement'

Python is a general-purpose programming language for Web and desktop development. Python works well on both of these platforms because of its flexibility, facilitated by its extensive list of built-in functions. By using the open() function and a simple loop, you can cycle through a list of file names and assign a variable with a reference to that file, storing it for later use.

1.

Create a list of file names. This requires you to enter the file names manually.

filenames = ['file1.txt', 'file2.txt', 'file3.txt']

2.

Create a variable to store the file contents. This variable will store the text of the file for each iteration. 'File_in' is an empty list that can store the contents of each file on each iteration.

file_in = list()

3.

Use a 'for' loop to cycle through each file name in the file name list. This will ensure each file opens and has a reference variable in the 'file_in' list:

x = 0 for item in filenames: . . . file_in[x] = open(item, 'r') . . . x += 1
