Hi all,



I've probably already shared this, but I thought that I'd share it again
anyways.



Here's a neat way you can create functions in your Koha XSLTs:



<xsl:stylesheet version="1.0"

xmlns:marc="http://www.loc.gov/MARC21/slim"

xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

xmlns:common="http://exslt.org/common"

xmlns:str="http://exslt.org/strings"

xmlns:func="http://exslt.org/functions"

xmlns:my="http://prosentient.com.au/xsltfunctions"

extension-element-prefixes="func"

exclude-result-prefixes="marc str my common">



<func:function name = "my:strToLower">

<xsl:param name="string" />

<xsl:variable name="lowercase" select="'abcdefghijklmnopqrstuvwxyz'"
/>

<xsl:variable name="uppercase" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"
/>

<xsl:variable name="translated" select="translate($string,
$uppercase, $lowercase)" />

<func:result select="$translated"/>

</func:function>



Most of the time you can probably just use templates with call-template and
a parameter, but I find functions can just be really handy.
