.SH DESCRIPTION
|
|
The
|
|
.B libexslt
|
|
library is used to provide extensions to
|
|
.SM XSLT
|
|
functions. These extensions come from the
|
|
.SM EXSLT
|
|
project <http://www.exslt.org/>
|
|
.LP
|
|
.SH USAGE
|
|
To make use of these functions in
|
|
.SM XSLT
|
|
the appropriate namespace must be defined on the
|
|
.B xsl:stylesheet
|
|
element. To enable support for them in
|
|
.BR libxslt (3)
|
|
you must call the appropriate functions (listed in the
|
|
.B SYNOPSIS
|
|
section) to register the extensions. The
|
|
.I xslt-config
|
|
shell script can be used to obtain the necessary flags for
|
|
the pre-processor and linker.
|
|
The supported extensions are:
