Continue to consider new features xsl-transformer  in Oracle XDK.
Now let's talk about the User-defined functions.

Custom functions appeared in 2 versions XSLT, so the version = "2.0" is necessary to specify the header of XSLT.


select ora_20000_xmlutility.XMLTransformClob
(xml_sample.xmltext,
q'~<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:foo="http://foo"
exclude-result-prefix="foo">

<xsl:function name="foo:twice">
<xsl:param name="p-string" />
<xsl:value-of select="concat($p-string, $p-string)" />
</xsl:function>

<xsl:template match="/">
<xsl:value-of select="foo:twice('Function plig-in. ')"/>
</xsl:template>
</xsl:stylesheet>
~' )
from xml_sample;

Result:



<?xml version = '1.0' encoding = 'UTF-8'?>
Function plig-in. Function plig-in.
