Hi, > Has anybody an idea how to implement an left-trim / > right-trim function which strips out all leading chars of a > string? If its not possible directly with standard xslt I can > also use XALAN built in function, but I never made this. <xsl:template name="left-trim"> <xsl:param name="s" /> <xsl:choose> <xsl:when test="normalize-space(substring($s, 1, 1)) = ''"> <xsl:call-template name="left-trim"> <xsl:with-param name="s" select="substring($s, 2)" /> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$s" /> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template name="right-trim"> <xsl:param name="s" /> <xsl:choose> <xsl:when test="normalize-space(substring($s, string-length($s))) = ''"> <xsl:call-template name="right-trim"> <xsl:with-param name="s" select="substring($s, 1, string-length($s) - 1)" /> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$s" /> </xsl:otherwise> </xsl:choose> </xsl:template> Shouldn't be difficult to combine the two.
