Subject: RE: [xsl] Is this about grouping ? From: Benoit_Aumars@xxxxxxxxxxxx Date: Mon, 2 Jul 2001 12:22:11 +0100 |
Mike, Trevor, Thanks for your reply. Obviously I did not clearly explained my problem. Let's start again. This is my original source ( with the correct indentation ) : <?xml version="1.0"?> <topic> <a>ItemA</a> <b>ItemB</b> <f>text1</f> <g>text2</g> <h>text3</h> <i>text4</i> <a>ItemA</a> <b>ItemB</b> <f>text5</f> <g>text6</g> <h>text7</h> <i>text8</i> <a>ItemA</a> <b>ItemB</b> <f>text9</f> <g>text10</g> <h>text11</h> <i>text12</i> </topic> and the result that I want to have ( with the correct indentation ) : <?xml version="1.0"?> <topic> <a>ItemA</a> <b>ItemB</b> <f>text1</f> <g>text2</g> <h>text3</h> <i>text4</i> <f>text5</f> <g>text6</g> <h>text7</h> <i>text8</i> <f>text9</f> <g>text10</g> <h>text11</h> <i>text12</i> </topic> So, I need to group by <a> and <b>. Those elements are constant in the source document. I will ignore the sort order because the original source is already sorted. If my XSL script is like this : <xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="xml" indent="yes" omit-xml-declaration="no" /> <xsl:key name="group" match="f | g | h | i" use="//a" /> <xsl:template match="topic"> <topic> <a> <xsl:value-of select="//a[1]"/> </a> <b> <xsl:value-of select="//b[1]"/> </b> <!-- <xsl:for-each select="key('group' ,a)"> <xsl:choose> <xsl:when test="//f"> <xsl:text/> <xsl:value-of select="."/><xsl:text/> </xsl:when> <xsl:otherwise> <xsl:text/> <xsl:value-of select="."/><xsl:text/> </xsl:otherwise> </xsl:choose> </xsl:for-each> --> <xsl:copy-of select="key('group' ,a)"/> </topic> </xsl:template> </xsl:transform> the result will be : <?xml version="1.0" encoding="UTF-8"?> <topic> <a>ItemA</a> <b>ItemB</b> <f>text1</f> <g>text2</g> <h>text3</h> <i>text4</i> <f>text5</f> <g>text6</g> <h>text7</h> <i>text8</i> <f>text9</f> <g>text10</g> <h>text11</h> <i>text12</i> </topic> The problem with that XSL using <xsl:copy-of> is that I can't control over the indentation from <f> to <i>. So I have to use the <xsl:for-each>. With <xsl:for-each>, I can control over the node-set returned by key(), i.e concatenate <f> and <g>. The above <xsl:for-each> is uncomplete or wrong completely. What I would like you to help me is how can I use <xsl:for-each> : 1. to have a proper indentation from <f> to <i> ? 2. to concatenate 2 elements ,i.e <f> and <g> into <new>, so the final result is : <?xml version="1.0" encoding="UTF-8"?> <topic> <a>ItemA</a> <b>ItemB</b> <new>text1+text2</new> <h>text3</h> <i>text4</i> <new>text5+text6</new> <h>text7</h> <i>text8</i> <new>text9+text10</new> <h>text11</h> <i>text12</i> </topic> I would appreciate any help.
