Install libxml2 in Linux

libxml2 is a library for parsing XML documents, and it is used by many applications and programming languages. In this tutorial, we'll cover how to install libxml2 on various Linux distributions.

Debian-based distributions (Debian, Ubuntu, Linux Mint, etc.):

On Debian-based systems, you can install libxml2 and its development files from the package repository using the apt package manager. First, update the package index by running:

sudo apt update

Next, install libxml2 and its development files:

sudo apt install libxml2 libxml2-dev

RHEL-based distributions (RHEL, CentOS, Fedora, etc.):

On RHEL-based systems, you can install libxml2 and its development files using the yum or dnf package manager.

For RHEL/CentOS 7:

Update the package index:

sudo yum update

Install libxml2 and its development files:

sudo yum install libxml2 libxml2-devel

For RHEL/CentOS 8 and Fedora:

Update the package index:

sudo dnf update

Install libxml2 and its development files:

sudo dnf install libxml2 libxml2-devel

Arch-based distributions (Arch Linux, Manjaro, etc.):

On Arch-based systems, you can install libxml2 and its development files using the pacman package manager.

Update the package index:

sudo pacman -Syu

Install libxml2 and its development files:

sudo pacman -S libxml2

After installing libxml2 on your Linux distribution, it will be available for use by other applications and programming languages that require it for parsing XML documents.

How to install libxml2 on Linux:
To install libxml2 using a package manager, use the relevant package manager for your distribution.
Example code (on Ubuntu):
