Re: [xsl] String comparison

[Wolfgang Laun <wolfgang.laun@xxxxxxxxx>]

Here's a  function:

<xsl:function name="wl:trdif">
  <xsl:param name="a" as="xsd:string"/>
  <xsl:param name="b" as="xsd:string"/>
  <xsl:choose>
    <xsl:when test="string-length($a) = 0 or
                    substring($a,1,1) != substring($b,1,1)">
      <xsl:value-of select="$b"/>
    </xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="wl:trdif(substring($a,2),substring($b,2))"/>
    </xsl:otherwise>
  </xsl:choose>
</xsl:function>

<xsl:template match="row">
  <xsl:value-of select="wl:trdif(@a,@b)"/>
</xsl:template>

--------------Input:
<table>
  <row a="123456" b="123456"/>
  <row a="123456" b="12345Z"/>
  <row a="123456" b="1234Y6"/>
  <row a="123456" b="123X56"/>
  <row a="123456" b="12W456"/>
  <row a="123456" b="1V3456"/>
  <row a="123456" b="U23456"/>
</table>

--------------Output:

  Z
  Y6
  X56
  W456
  V3456
  U23456
