## プロジェクトの歴史と使われ方

libxml2 is the GNOME XML C parser and toolkit, but its reach extends far beyond GNOME. It became one of the default XML implementations for Unix-like systems because it combines parser, tree API, validation support, HTML parsing, catalog handling, command-line tools, and language bindings in a portable C library.

### プロジェクトの歴史

The libxml2 documentation describes the project as an XML toolkit implemented in C and originally developed for the GNOME Project. The historical xmlsoft.org documentation credited Daniel Veillard as the maintainer and pointed users to GNOME CVS modules for libxml2 and libxslt.

GNOME's release archive contains the libxml2 2.0.0 source tarball dated 2000-04-12. The project's public documentation records the GNOME GitLab repository and the GNOME download archive as official locations, showing the migration from the older xmlsoft/GNOME CVS era to GNOME-hosted GitLab and generated API documentation.

### 採用の歴史

libxml2 was adopted widely because XML was a core interchange format for desktop files, configuration formats, documentation systems, web service stacks, office formats, and build tooling. Its permissive MIT license, C API, portability, and bindings made it attractive to distributions and application runtimes.

The command-line tools xmllint and xmlcatalog gave the library a direct package-manager presence. Even users who never linked libxml2 could install the package to validate XML, inspect documents, test XPath expressions, or manage XML catalogs in build and documentation pipelines.

### 使われ方

Common package usage includes linking against libxml2 for parsing and validation, using xmllint in scripts and tests, and using xmlcatalog where systems rely on XML catalog resolution. It is also a dependency layer for related XML software such as libxslt and xmlsec.

### パッケージ好きにとっての重要性

libxml2 is package-nerd infrastructure: small enough to be considered a library dependency, but important enough that parser behavior, security fixes, and ABI expectations affect browsers, language ecosystems, desktop software, and distro bootstrap graphs. Its presence in package managers is a sign that XML support is part of the Unix substrate rather than a niche add-on.

### タイムライン

- 2000: GNOME's source archive lists libxml2 2.0.0 dated 2000-04-12.
- 2002: Historical xmlsoft documentation points to GNOME CVS modules for libxml2 and libxslt.
- 2022: GNOME-hosted API documentation records the project repository on GNOME GitLab.
- 2026: GNOME's source archive lists maintained 2.x release directories through the 2.15 series.

### Related projects

- libxslt builds on the same GNOME XML stack for XSLT processing. XML Security Library uses libxml2 as its XML foundation. Higher-level bindings and wrappers expose libxml2 to languages such as Python, Perl, Ruby, PHP, and others.
