Subject: [xsl] multiple attributes From: DPawson@xxxxxxxxxxx Date: Fri, 13 Dec 2002 13:03:17 -0000 |
problem. <xsl:param name="wanted" select="''"/> <element att="a b c d"> wanted, contains both a and b </element> <element> wanted, has no att attribute </element> <element att="x"> not wanted, block it. </element> I want to run an identity transform, but only select those elements which either have no @att, or have an att value which is one of those passed into the stylesheet as a command line param, e.g. saxon file.xml ss.xsl "wanted= a b" should only copy through those elements having an att value which contains one or both of a, b. Hope that's clear. I can't recall seeing a mxn contains string thingy. I'm getting stuck with a recursion solution. Any help appreciated. TIA DaveP. <xsl:template match="*[@targets]"> <xsl:variable name="inTarget"> <xsl:call-template name="tgt"> <xsl:with-param name="wanted" select="$targets"/> <xsl:with-param name="this-elements-targets" select="@targets"/> </xsl:call-template> </xsl:variable> <xsl:choose> <xsl:when test="$inTarget"> <!-- Copy through, wanted --> <xsl:copy> <xsl:copy-of select="@*"/> <xsl:apply-templates/> </xsl:copy> </xsl:when> <xsl:otherwise/> <!-- block, not wanted --> </xsl:choose> </xsl:template> <xsl:template name="tgt"> <xsl:param name="wanted" select="''"/> <xsl:param name="this-elements-targets" select="''"/> <xsl:if test="$debug"> <xsl:message> tgt: wanted <xsl:value-of select="$wanted"/> this els: <xsl:value-of select="$this-elements-targets"/> </xsl:message> </xsl:if> <xsl:variable name="onetarget" select="substring-before($this-elements-targets,'+')"/> <xsl:if test="contains($wanted, $onetarget)"> <xsl:value-of select="true"/> </xsl:if> <xsl:choose> <xsl:when test="string-length($this-elements-targets)= 0"> <xsl:value-of select="false()"/> </xsl:when> <xsl:otherwise> <xsl:call-template name="tgt"> <xsl:with-param name="this-elements-targets" select="substring-after($this-elements-targets,'+')"/> <!-- presently uses + character as seperator. perhaps change to space character --> <xsl:with-param name="wanted" select="$wanted"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:template> Regards DaveP. **** snip here ***** - NOTICE: The information contained in this email and any attachments is confidential and may be legally privileged.
