Expat is a library, written in C, for parsing XML documents. It's the underlying XML parser for the open source Mozilla project, perl's XML::Parser, and other open-source XML parsers. Expat is a stream-oriented parser in which an application registers handlers for things the parser might find in the XML document. Expat it's very fast and also sets a high standard for reliability, robustness and correctness.

This software is distributed in two modes:

as compressed package that you have to download and manually install; if prerequisites are required, you will have to manually install them too;
as RPM package; you can install it using your favorite rpm package manager, that will take care to download and install both the software and its prerequisites.

Choose the installation mode that you prefer. Please note that not all the versions are available in both the installation modes.

Installation with rpm

This program is installable using the rpm package manager. See below for the install string. Required prerequisites are automatically processed by the package manager and, if needed, downloaded and installed.
