Chuck, In your 'image' template, do something like this: <xsl:template match="image"> <td> Path: <a href="{thumbimage/thumbpath}"> <xsl:value-of select="thumbimage/thumbpath"/></a> Description: <xsl:choose> <xsl:when test="title"> <xsl:value-of select="substring(title,1,25)"/> </xsl:when> <xsl:when test="description"> <xsl:value-of select="substring(description,1,25)"/> </xsl:when> <xsl:otherwise> <xsl:value-of select="substring(id,1,25)"/> </xsl:otherwise> </xsl:choose> </td> </xsl:template> If <title> or <description> elements may be present but empty, you'll have to use a different test, like: <when test="title != ''"> Good luck, --Paul ----- Original Message ----- From: "Chuck Thomas" <thoma134@xxxxxxxxxx> To: <xsl-list@xxxxxxxxxxxxxxxxxxxxxx> Sent: Friday, September 28, 2001 9:01 AM Subject: [xsl] need further assistance with grouping nodes into groups of 3 > Hi All, > > I am very familiar with basic to intermediate xslt, but this one is a bit > beyond my current knowledge, so any help is appreciated. > > The list archive was partially useful for my request, but I am still having > difficulties. > > I am working with xml documents structured like: > > <images> > <image> > <id>mandatory info here</id> > <title>optional element info may be here</title> > <description>optional element info may be here</description> > <thumbimage> > <thumbpath>http://xxx.xxx.xxx/xxx</thumbpath> > <thumbformat>MIME info, etc.</thumbformat> > </thumbimage> > </image> > > <image> > <id>mandatory info here</id> > <title>optional element info may be here</title> > <description>optional element info may be here</description> > <thumbimage> > <thumbpath>http://xxx.xxx.xxx/xxx</thumbpath> > <thumbformat>MIME info, etc.</thumbformat> > </thumbimage> > </image> > </images> > > The <images> wrapper contain multiple <image> children. > > What I'd like to do is: > > a) create an HTML table that breaks the <image> children into groups of > three, so that the table is only 3 columns wide, and contains as many rows > as there are groups of three, and > > b) display in each table cell: > 1) the value of the record's thumbpath element > 2) the first 25 characters of just one of the following elements, in this > order of precendence (<title>, <description>, or <id>) > > The list archive contains some clues on how to break the records into > groups of 3, but I need further clarification, especially when trying to > combine it with these other functional requirements. > > Any suggestions would be appreciated greatly. > > Sincerely, > Chuck Thomas > > > > ******************************************************** > INTERVIEWER: "Have you made any contributions to culture?" > ELVIS: "Like income taxes, you mean?" > > --From THE QUOTABLE KING > (Nashville: Cumberland House, 1997) > > "Qui me amat, amet et canem meum" (Love me, love my dog) > - A proverb mentioned by St. Bernard in his SERMO PRIMUS > > Charles F.
