Simple XSLT Construct Tester

When it comes to testing xquery constructs I find the easiest method is to use MArkLogics CQ interface. A simple answer to doing the same with XSLT is to use a single named template in an XSLT

Just create a basic XSLT named tester.xsl and add in one named template called 'testConstruct' and call it using the following command line

java -jar saxon.jar -it:testConstruct -xsl:tester.xsl -o:result.xml

The sample below tests creation of a string reconstruction from a test string

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:template name="testConstruct">
 <xsl:variable name="provisions" select="'Sch. 08 para. 028(02) para. 058(03)A Sch. 15'" />
 <xsl:variable name="schtokens" select="tokenize($provisions, 'Sch. ')" />
 <xsl:for-each select="$schtokens">
  <xsl:variable name="paraTokens" select="tokenize(substring-after(., ' '), 'para.')" />
  <xsl:variable name="schNo" select="if (contains(., ' ')) then substring-before(., ' ')   else ." />
  <xsl:value-of select="if (not(matches(., '^\s*$')) and contains(., 'para')) then 
    (concat('Sch. ', $schNo, ' para.', substring-before($paraTokens[2],'('), 
     string-join(for $p in $paraTokens return replace(normalize-space($p), '^[0-9]+', ''),'')) )
    else if (not(matches(., '^\s*$'))) then 
    ( concat('Sch. ', $schNo) ) 
    else ()" />
  <xsl:if test="not(position() = last())">
   <xsl:value-of select="' '"/>
