Re: [xsl] RE: String manipulation in XSLT

[Mukul Gandhi <gandhi.mukul@xxxxxxxxx>]

Please try this stylesheet

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                       xmlns:common="http://exslt.org/common";
                       version="1.0">

<xsl:output method="text" />

<xsl:variable name="str" select="'abc.def.ghi'" />

<xsl:template match="/">
  <xsl:variable name="rtf">
    <string>
      <xsl:call-template name="reform_string">
        <xsl:with-param name="str" select="$str" />
        <xsl:with-param name="delim" select="'.'" />
      </xsl:call-template>
    </string>
  </xsl:variable>
  <xsl:variable name="package">
    <xsl:for-each select="common:node-set($rtf)/string/part">
      <xsl:if test="position() != last()">
        <xsl:value-of select="." />
      </xsl:if>
      <xsl:if test="position() &lt; (last() - 1)">
        .
      </xsl:if>
    </xsl:for-each>
  </xsl:variable>
  Package name - <xsl:value-of select="translate($package,'&#xa; ','')" />
  Class name - <xsl:value-of
select="common:node-set($rtf)/string/part[last()]" />
</xsl:template>

<xsl:template name="reform_string">
  <xsl:param name="str" />
  <xsl:param name="delim" />

  <xsl:choose>
    <xsl:when test="contains($str,'.')">
      <part><xsl:value-of select="substring-before($str,'.')" /></part>
      <xsl:call-template name="reform_string">
        <xsl:with-param name="str" select="substring-after($str,'.')" />
        <xsl:with-param name="delim" select="$delim" />
      </xsl:call-template>
    </xsl:when>
    <xsl:otherwise>
      <part><xsl:value-of select="$str" /></part>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

</xsl:stylesheet>

This was tested with Saxon 8.5.1 as
java net.sf.saxon.Transform file.xsl file.xsl

(The stylesheet filename is file.xsl)

Hope you can take some ideas from this..

I do enjoy writing XSLT stylesheets! If you can, you can move to XSLT
2.0. It has lot of new constructs and functions, which reduce the
program size considerably.
