xslt check for alpha numeric character
- by Newcoma
I want to check if a string contains only alphanumeric characters OR '.'
This is my code. But it only works if $value matches $allowed-characters exactly. I use xslt 1.0.
<xsl:template name="GetLastSegment">
<xsl:param name="value" />
<xsl:param name="separator" select="'.'" />
<xsl:variable name="allowed-characters">ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz.</xsl:variable>
<xsl:choose>
<xsl:when test="contains($value, $allowed-characters)">
<xsl:call-template name="GetLastSegment">
<xsl:with-param name="value" select="substring-after($value, $separator)" />
<xsl:with-param name="separator" select="$separator" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$value" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
