Introduction

In this tutorial we learn how to install libxml2 on CentOS 8.

What is libxml2

This library allows to manipulate XML files. It includes support to read, modify and write XML and HTML files. There is DTDs support this includes parsing and validation even with complex DtDs, either at parse time or later once the document has been modified. The output can be a simple SAX stream or and in-memory DOM like representations. In this case one can use the built-in XPath and XPointer implementation to select sub nodes or ranges. A flexible Input/Output mechanism is available, with existing HTTP and FTP modules and combined to an URI library. libxml2 2.9.7 9.el8_4.2 i686 741 k libxml2-2.9.7-9.el8_4.2.src.rpm baseos Library providing XML and HTML support http MIT This library allows to manipulate XML files.

We can use yum or dnf to install libxml2 on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install libxml2.

Install libxml2 on CentOS 8 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh
