Re: [xsl] incrementing a variable

[John Moylan <john at rte dot ie>]

Thanks Andrew,

To complete the thread, and just in case anyone else is searching this 
list for incrementing code, here is mine:

<xsl:variable name="NUMIMAGES">
                                       <xsl:value-of select 
="count(/NewsML/NewsItem/NewsComponent/NewsItem/NewsComponent/NewsComponent/ContentItem/Encoding/DataContent)" 
/>
                               </xsl:variable>
                               <td><xsl:for-each select = 
'//Encoding/DataContent'>
                                       <xsl:element name="a">
                                               <xsl:attribute 
name="href"><xsl:value-of select="$page-name"/>.<xsl:value-of select = 
"$NUMIMAGES - position() + 1"/>.jpg</xsl:attribute>
                                       <b>
                                               Click here for Article!<br/>
                                       </b>
                                       </xsl:element>
                               </xsl:for-each>
