DESCRIPTION
The libexslt library is used to provide extensions to XSLT functions. These extensions come from the EXSLT project <http://www.exslt.org/>
USAGE
To make use of these functions in XSLT the appropriate namespace must be defined on the xsl:stylesheet element. To enable support for them in libxslt(3) you must call the appropriate functions (listed in the SYNOPSIS section) to register the extensions. The xslt-config shell script can be used to obtain the necessary flags for the pre-processor and linker. The supported extensions are:
COMMON
- Namespace: http://exslt.org/common
- See http://www.exslt.org/exsl/index.html for a description.
- node-set()
- convert the given RTF into a node-set.
- object-type()
- returns the type of the given argument.
- document
- Create multiple output documents. See http://www.exslt.org/exsl/elements/document/index.html
