XSL template to split string

May 16, 2008

Finally came up with a xslt template that would split a delimited string into substrings.
I don’t claim it’s the smartest script, but surely solves my problem.

Stylesheet:


<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:for-each select="Paths/Item">
<xsl:call-template name="SplitText">
<xsl:with-param name="inputString" select="Path"/>
<xsl:with-param name="delimiter" select="Delimiter"/>
</xsl:call-template>
<br/>
</xsl:for-each>
</xsl:template>
<xsl:template name="SplitText">
<xsl:param name="inputString"/>
<xsl:param name="delimiter"/>
<xsl:choose>
<xsl:when test="contains($inputString, $delimiter)">
<xsl:value-of select="substring-before($inputString,$delimiter)"/>
<xsl:text disable-output-escaping = "no"> </xsl:text>
<xsl:call-template name="SplitText">
<xsl:with-param name="inputString" select="substring-after($inputString,$delimiter)"/>
<xsl:with-param name="delimiter" select="$delimiter"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:choose>
<xsl:when test="$inputString = ''">
<xsl:text></xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$inputString"/>
<xsl:text> </xsl:text>
</xsl:otherwise>
</xsl:choose>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>


XML file (to be transformed) :


<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="textSpliter.xslt"?>
<Paths>
  <Item>
    <Path>C:\ProgramFiles\SomeWierdSoftware</Path>
    <Delimiter>\</Delimiter>
  </Item>
</Paths>


Output: C: ProgramFiles SomeWierdSoftware
Hope it is useful.
