Subject: [xsl] Multiple grouping with substrings From: Ben Fry <Ben_Fry@xxxxxxxxxxxxx> Date: Tue, 13 Aug 2002 16:53:15 +0100 |
Hi All, I have a grouping problem I cannot work out. I have done a couple of stylesheets with keys but this one has me befuddled. I am having trouble declaring and using a key like this; (I am new to keys so go easy here) <xsl:key name="xprogs" match="doc/prog[contains(.,'msx']" use="substring(.,4,1)"/> My algorithm is a). Group by 3rd character of prog node ie 'x' in msx123 followed by 'y' in msy123 b). For each unique 4th character of prog node list prog nodes 4 (or ideally custom value) per line separated by a single space (produce new line when a different 4th character encountered). xml; <doc> <prog>msx123</prog> <prog>msx124</prog> <prog>msx125</prog> <prog>msx126</prog> <prog>msx127</prog> <prog>msx128</prog> <prog>msx129</prog> <prog>msx213</prog> <prog>msx332</prog> <prog>msx423</prog> <prog>msx424</prog> <prog>msx643</prog> <prog>msx743</prog> <prog>msx843</prog> <prog>msy123</prog> <prog>msy223</prog> <prog>msy224</prog> <prog>msy423</prog> </doc> desired output text format; xxx123 xxx124 xxx125 xxx126 xxx127 xxx128 xxx129 xxx213 xxx332 xxx423 xxx424 xxx643 xxx743 xxx843 yyy123 yyy223 yyy224 yyy423 Regards, Ben ===================================================================== DISCLAIMER 1.
