EXSLT is a set of extensions to XSLT. There are a number of modules; those that are supported by Firefox are listed below:

Common (exsl)
The EXSLT Common package provides basic functions that expand upon the capabilities of XSLT.
Math (math)
The EXSLT Math package provides functions for working with numeric values and comparing nodes.
Regular expressions (regexp)
The EXSLT Regular Expressions package provides functions that allow testing, matching, and replacing text using JavaScript style regular expressions.
Sets (set)
The EXSLT Sets package offers functions that let you perform set manipulation.
Strings (str)
The EXSLT Strings package provides functions that allow the manipulation of strings.

EXSLT modules

To use an EXSLT function, you need to declare the namespace the function is in, and then use the appropriate prefix when calling the function. For example, to use the regular expressions package:

<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:regexp="http://exslt.org/regular-expressions">
  <xsl:template match="/">
    ...
    <xsl:value-of select="regexp:replace(/root/@value, 'before', 'gi', 'AFTER')"/>
    ...
  </xsl:template>

</xsl:stylesheet>
