**libxslt** is the [XSLT](/source/XSLT) [C](/source/C_programming_language) library developed for the [GNOME](/source/GNOME) project. It provides an implementation of XSLT 1.0, plus most of the [EXSLT](/source/EXSLT) set of processor-portable extensions functions and some of [Saxon](/source/Saxon_XSLT)'s evaluate and expressions extensions. libxslt is based on [libxml2](/source/Libxml2), which it uses for [XML](/source/XML) parsing, tree manipulation and [XPath](/source/XPath) support. It is [free software](/source/Free_software) released under the [MIT License](/source/MIT_License) and can be reused in commercial applications.

libxslt can be used either as library embedded into an application, or via the [xsltproc](http://xmlsoft.org/XSLT/xsltproc.html) command line tool. The integration into applications is eased by a multitude of [language bindings and wrappers](http://xmlsoft.org/XSLT/python.html). Being written in C, libxslt is a fast and low-resource processor.[1][2][3] This makes it a popular choice for [DocBook](/source/DocBook) formatting[4] and as standard XSLT processor for [programming languages](/source/Programming_language) like [PHP](/source/PHP),[5] [Perl](/source/Perl)[6] or [Python](/source/Python_(programming_language)).[7]

The [WebKit](/source/WebKit) layout engine (used e.g. in the [Apple Safari](/source/Apple_Safari) web browser) uses the libxslt library to do XSL transformations.[8]

The project was marked as unmaintained in July 2025 following the stepping down of Nick Wellnhofer.[9] In August 2025, Iván Chavero became the sole maintainer of the project.[10]
