Neal WaltersSubject: Grouping items
Author: Neal Walters

My other task is take an element and group it into groups of 14.
I recall from the past that even incrementing a counter is kind of tricky. So while I'm looping, if the counter is < 14 I move a group to a a group, but once the counter is 14, I have to reset counter to 1, and start a new group on the target doc.

Any suggestions or tricks? Seems like last time I needed a counter the easiest way to do it was with a C# subroutine (I'm in the .NET world).

Thanks in advance,
Neal

See attached. The goal in this simplified version is to group the line-items by 3. The first three line items go together, then the second three, then the 7th one is left by itself.

Thanks,
Neal

I'm thinking about using position() and trying to use modular division - maybe then I don't need a counter.

Here's where I'm headed, ( am properly displaying the position() and the mods, but what's confusing me is how to write out the <body> tag optionally - and to keep the XML in the XSLT well-formed i.e. "balanced".


<?xml version='1.0' ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<groupdemoin>
<xsl:for-each select="groupdemoin/body/bodylineitem/bodyline">
<xsl:if test="position() mod 3 = 0">
<body>
</body>
</xsl:if>


<bodylineitem>
<bodyline>
<xsl:value-of select="position()"/>
</bodyline>
<bodydivision>
<xsl:value-of select="position() mod 3"/>
</bodydivision>
<bodystuff>temp</bodystuff>
</bodylineitem>
</body>
</xsl:for-each>
</groupdemoin>
</xsl:template>
</xsl:stylesheet>

Thanks,

This is a basic paging problem, see the attached solution

That is so cool!

Can you send me a reference that explains the pipe symbol
in this statement:
". | following-sibling::bodylineitem[position() < $pagesize]">

Is it acting as an "OR" here? Select current node or the other node?
If so, I didn't know you could put an "OR" in a for-each...

Thanks,
Neal

| is the nodeset union operator see http://www.w3.org/TR/xpath#node-sets
