Subject: RE: [xsl] Split a string and fill it in a table (xslt1.0) From: "Hofman, Peter" <peter.hofman@xxxxxxxxxxxxx> Date: Fri, 17 Aug 2007 14:06:21 +0200 |
Hi Christoph, After having done mostly XSLT 2.0 lately, I thought it would be nice to try solve some XSLT 1.0 problem. This is what I can come up with. Basically the same thing, only I implemented your eater template a bit different (with recursion), allowing different row sizes. Empty elements are added to the row when not enough data is provided. If you need a more or less columns, you Can pass param row-size to make-table template. This stylesheet works with msxsl. No extension functions used. To do: Some checks need to be added to check for empty strings when entering a templated. But I leave that up to you. <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output encoding="UTF-8" method="xml" indent="yes"/> <xsl:template match="/"> <xsl:apply-templates/> </xsl:template> <xsl:template match="root"> <xsl:apply-templates/> </xsl:template> <xsl:template match="transform"> <xsl:call-template name="make-table"> <xsl:with-param name="list" select="normalize-space(text())"/> </xsl:call-template> </xsl:template> <xsl:template name="make-table"> <xsl:param name="list"/> <xsl:param name="row-size" select="4"/> <table> <xsl:call-template name="output-rows"> <xsl:with-param name="list" select="$list"/> <xsl:with-param name="row-size" select="$row-size"/> </xsl:call-template> </table> </xsl:template> <xsl:template name="output-rows"> <xsl:param name="list"/> <xsl:param name="row-size"/> <xsl:if test="string-length($list) > 0"> <xsl:variable name="elements-list"> <xsl:call-template name="get-elements"> <xsl:with-param name="list" select="$list"/> <xsl:with-param name="count" select="$row-size"/> </xsl:call-template> </xsl:variable> <xsl:comment><xsl:value-of select="$elements-list"/></xsl:comment> <tr> <xsl:call-template name="output-elements"> <xsl:with-param name="elements-list" select="$elements-list"/> </xsl:call-template> </tr> <xsl:call-template name="output-rows"> <xsl:with-param name="list" select="substring-after($list,$elements-list)"/> <xsl:with-param name="row-size" select="$row-size"/> </xsl:call-template> </xsl:if> </xsl:template> <xsl:template name="output-elements"> <xsl:param name="elements-list"/> <td> <xsl:value-of select="substring-before($elements-list,' ')"/> </td> <xsl:if test="substring-after($elements-list,' ')!=''"> <xsl:call-template name="output-elements"> <xsl:with-param name="elements-list" select="substring-after($elements-list,' ')"/> </xsl:call-template> </xsl:if> </xsl:template> <xsl:template name="get-elements"> <xsl:param name="list"/> <xsl:param name="count"/> <xsl:if test="$count > 0"> <xsl:variable name="elements-list"> <xsl:call-template name="get-elements"> <xsl:with-param name="list" select="substring-after($list,' ')"/> <xsl:with-param name="count" select="$count - 1"/> </xsl:call-template> </xsl:variable> <xsl:value-of select="concat(substring-before(concat($list,' '),' '),' ',$elements-list)"/> </xsl:if> </xsl:template> </xsl:stylesheet> Regards, Peter >-----Original Message----- >From: christoph.naber@xxxxxxxxxxxxxxxxxxx >[mailto:christoph.naber@xxxxxxxxxxxxxxxxxxx] >Sent: vrijdag 17 augustus 2007 11:19 >To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx >Subject: [xsl] Split a string and fill it in a table (xslt1.0) > >Hello list, > >(XSLT 1.0, afaik MSXML (I dont use the stylesheets, they are >included in some visual basic programs)) I wonder about whats >a good way to split a string at whitespaces and fill it into a >table which has four rows and four columns.
