6.5 Using Extension Functions

XSLT is an excellent tool for performing some kinds of transformations and a rather poor tool for
other types of transformations, such as non-trivial string manipulation and iterative processes.
However, the Novell XSLT processor implements extension functions that allow the style sheet to
call a function implemented in Java, and by extension, any other language that can be accessed
through JNI.
For specific examples, see
following example that illustrates using Java for string manipulation. The long lines are wrapped
and do not begin with a <. To view the style sheet, see
Extension_Functions.xsl).
<!-- get-dn-prefix places the part of the passed dn that -->
<!-- precedes the last occurrence of '\' in the passed dn -->
<!-- in a result tree fragment meaning that it can be
<!-- used to assign a variable value
<xsl:template name="get-dn-prefix" xmlns:jstring="http://
www.novell.com/nxsl/java/java.lang.String">
<add-value>
<value type="string">Engineering</value>
</add-value>
