title: Trying to add line breaks inside a template in XSLT
body: <p>I have an XSLT file that is rendering an HTML page, I am trying to split the string by using <code>;</code> as the delimiter and then adding line breaks every EVEN break. I have my code below, it doesn't seem to work, the line breaks don't appear:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt;
  
  &lt;td width="50%" nowrap="nowrap"&gt;
   &lt;xsl:call-template name="split-parent" /&gt;
  &lt;/td&gt;
  
  ....
  
   &lt;xsl:template match="STUDENT_DETAILS/PARENT" name ="split-parent"&gt;
      &lt;xsl:variable name="splitParentsVar"&gt;
          &lt;xsl:call-template name="add-line-breaks"&gt;
              &lt;xsl:with-param name="stringToBreak" select="STUDENT_DETAILS/PARENT"/&gt;
              &lt;xsl:with-param name="isEven" select="0"/&gt;
          &lt;/xsl:call-template&gt;
      &lt;/xsl:variable&gt;
      &lt;xsl:value-of select="$splitParentsVar"/&gt;
  &lt;/xsl:template&gt;
  &lt;xsl:template name="add-line-breaks"&gt;
      &lt;xsl:param name="stringToBreak"/&gt;
      &lt;xsl:param name ="isEven" /&gt;
      &lt;xsl:if test ="$isEven='1'"&gt;
          &lt;xsl:value-of select="concat($stringToBreak,'&amp;#xa;')"/&gt;
          &lt;xsl:if test="substring-after($stringToBreak,';')!=''"&gt;
              &lt;xsl:call-template name="add-line-breaks"&gt;
                  &lt;xsl:with-param name="stringToBreak" select="substring-after($stringToBreak,';')"/&gt;
                  &lt;xsl:with-param name="isEven" select="0"/&gt;
              &lt;/xsl:call-template&gt;
          &lt;/xsl:if&gt;
      &lt;/xsl:if&gt;
      &lt;xsl:if test="$isEven='0'"&gt;
          &lt;xsl:value-of select="$stringToBreak"/&gt;
          &lt;xsl:if test="substring-after($stringToBreak,';')!=''"&gt;
              &lt;xsl:call-template name="add-line-breaks"&gt;
                  &lt;xsl:with-param name="stringToBreak" select="substring-after($stringToBreak,';')"/&gt;
                  &lt;xsl:with-param name="isEven" select="1"/&gt;
              &lt;/xsl:call-template&gt;
          &lt;/xsl:if&gt;
      &lt;/xsl:if&gt;
  &lt;/xsl:template&gt;
  ....
  </code></pre>
  
  <p>An example of the input would be:</p>
  
  <p>George Aaron; Susan Lee Aaron; Richard Elliot Aaron; Albert Smith; Carry Johnson</p>
  
  <p>output would be something like:</p>
  
  <p>George Aaron; Susan Lee Aaron; <br/>Richard Elliot Aaron; Albert Smith; <br/> Carry Johnson</p>
  
  <p>The input XML looks something like this:</p>
  
  <pre><code>&lt;NewDataSet&gt;
      &lt;REPORT_OPTIONS&gt;
          &lt;RANK_RUN&gt;12/04/2013&lt;/RANK_RUN&gt;
          &lt;PRNT_WGHT_AVGE&gt;False&lt;PRNT_WGHT_RANK&gt;
      &lt;/REPORT_OPTIONS&gt;
      &lt;STUDENT_DETAILS&gt;
          &lt;STUD_PK&gt;1590&lt;/STUD_PK&gt;
          &lt;STUD_NAME&gt;Robert SMith&lt;/STUD_NAME&gt;
          &lt;PARENT&gt;jubju Aaron; Susan Lee Aaron; Richard Elliot Aaron; Carl Smith&lt;/PARENT&gt;
      &lt;/STUDENT_DETAILS&gt;
  &lt;/NewDataSet&gt;
  </code></pre>
  
  <p>I want to modify the <code>&lt;PARENT&gt;</code> tag so that every two parents there is a line break that will be rendered in HTML (Whatever the best way to do this is).</p>
