Hello I do not know the difference, but it seems that I can not use this header: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:exsl="http://exslt.org/common"; exclude-result-prefixes="exsl" version="1.0"> Tag form template David Carlisle: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:exslt="http://exslt.org/common"; version="1.0"> was accepted but this one in my system display nothing. His template works correctly. My system don't support exslt well. I wonder if it is a question of this declaration or function of exsl which you used. I don't know which may be reason of this problem. Static columns are OK. I lost many hours trying to make recursive columns, and it is quite good idea for this problem. Kind regards. 2009/9/19 Martin Honnen <Martin.Honnen@xxxxxx>: > J23 wrote: > >> xml input: >> <?xml version="1.0"?> >> <?xml-stylesheet href="xsl.xsl" type="text/xsl" ?> >> <elements> >> <Row Nr="1"> >> <name>Mark</name> >> <value>1</value> >> <code>22</code> >> </Row> >> <Row Nr="2"> >> <name>Mark</name> >> <value>1</value> >> <code>1</code> >> </Row> >> >> <Row Nr="3"> >> <name>Paul</name> >> <value>2</value> >> <code>2</code> >> </Row> >> <Row Nr="4"> >> <name>Mark</name> >> <value>1</value> >> <code>2</code> >> </Row> >> <Row Nr="5"> >> <name>Peter</name> >> <value>44</value> >> <code>2</code> >> </Row> >> <Row Nr="6"> >> <name>Peter</name> >> <value>1</value> >> <code>0</code> >> </Row> >> <Row Nr="7"> >> <name>Paul</name> >> <value>11</value> >> <code>1</code> >> </Row> >> <Row Nr="8"> >> <name>Peter</name> >> <value>11</value> >> <code>1</code> >> </Row> >> <Row Nr="9"> >> <name>Mark</name> >> <value>13</value> >> <code>0</code> >> </Row> >> <Row Nr="10"> >> <name>Peter</name> >> <value>13</value> >> <code>1</code> >> </Row> >> <Row Nr="11"> >> <name>Paul</name> >> <value>14</value> >> <code>1</code> >> </Row> >> </elements> > > The following stylesheet > > <xsl:stylesheet > xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; > xmlns:exsl="http://exslt.org/common"; > exclude-result-prefixes="exsl" > version="1.0"> > > <xsl:output method="html" indent="yes"/> > > <xsl:key name="k1" match="Row[not(code = 0)]" use="name"/> > <xsl:key name="k2" match="Row[not(code = 0)]" use="concat(name, '|', > value)"/> > <xsl:key name="k3" match="data" use="concat(../@key, '|', @count)"/> > > <xsl:variable name="cols-rtf"> > <td>1</td> > <td>2</td> > <td>3</td> > <td>4</td> > <td>5</td> > </xsl:variable> > > <xsl:variable name="cols" select="exsl:node-set($cols-rtf)/td"/> > > <xsl:template match="/"> > <html> > <head> > <title>Example</title> > </head> > <body> > <xsl:variable name="groups-rtf"> > <xsl:for-each select="elements/Row[not(code = 0)][generate-id() = > generate-id(key('k1', name)[1])]"> > <group key="{name}"> > <xsl:for-each select="key('k1', name)[generate-id() = > generate-id(key('k2', concat(name, '|', value))[1])]"> > <xsl:sort select="count(key('k2', concat(name, '|', value)))" > data-type="number"/> > <data value="{value}" count="{count(key('k2', concat(name, > '|', value)))}"/> > </xsl:for-each> > </group> > </xsl:for-each> > </xsl:variable> > <xsl:variable name="groups" > select="exsl:node-set($groups-rtf)/group"/> > <table border="1"> > <thead> > <tr> > <th>Name</th> > <th colspan="{count($cols)}">Values repeated n time(s)</th> > </tr> > <tr> > <th></th> > <xsl:copy-of select="$cols"/> > </tr> > </thead> > <tbody> > <xsl:for-each select="$groups"> > <xsl:variable name="cg" select="."/> > <tr> > <td><xsl:value-of select="@key"/></td> > <xsl:for-each select="$cols"> > <xsl:variable name="col" select="."/> > <td> > <xsl:for-each select="$cg"> > <xsl:variable name="dg" select="key('k3', concat(@key, > '|', $col))"/> > <xsl:choose> > <xsl:when test="$dg"> > <xsl:value-of select="count($dg)"/> > <xsl:text> (values </xsl:text> > <xsl:for-each select="$dg"> > <xsl:value-of select="@value"/> > <xsl:if test="position() != last()"> > <xsl:text>, </xsl:text> > </xsl:if> > </xsl:for-each> > <xsl:text>)</xsl:text> > </xsl:when> > <xsl:otherwise>0</xsl:otherwise> > </xsl:choose> > </xsl:for-each> > </td> > </xsl:for-each> > </tr> > </xsl:for-each> > </tbody> > </table> > </body> > </html> > </xsl:template> > > </xsl:stylesheet> > > produces the following result: > > <html> > <head> > <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> > > <title>Example</title> > </head> > <body> > <table border="1"> > <thead> > <tr> > <th>Name</th> > <th colspan="5">Values repeated n time(s)</th> > </tr> > <tr> > <th></th> > <td>1</td> > <td>2</td> > <td>3</td> > <td>4</td> > <td>5</td> > </tr> > </thead> > <tbody> > <tr> > <td>Mark</td> > <td>0</td> > <td>0</td> > <td>1 (values 1)</td> > <td>0</td> > <td>0</td> > </tr> > <tr> > <td>Paul</td> > <td>3 (values 2, 11, 14)</td> > <td>0</td> > <td>0</td> > <td>0</td> > <td>0</td> > </tr> > <tr> > <td>Peter</td> > <td>3 (values 44, 11, 13)</td> > <td>0</td> > <td>0</td> > <td>0</td> > <td>0</td> > </tr> > </tbody> > </table> > </body> > </html> > > I hope that reflects what you want to achieve. > I cheated however by putting five columns statically in the stylesheet.
