Numbering problem

EstherMStrom · January 21st, 2005, 03:21 PM

I have what I think may be a strange numbering issue.

Here's the basic setup of the XML source:

<NavigationDivision PEDivRef="a1">
    <NavigationDivision PEDivRef="b1">
        <NavigationDivision PEDivRef="c1">
            <ActivityInContext>
                <Activity id="c1a"/>
            </ActivityInContext>
        </NavigationDivision>
        <NavigationDivision PEDivRef="c2">
            <ActivityInContext>
                <Activity id="c2a"/>
            </ActivityInContext>
        </NavigationDivision>
        <ActivityInContext>
            <Activity id="b1a"/>
        </ActivityInContext>
        <ActivityInContext>
            <Activity id="b1b"/>
        </ActivityInContext>
        <ActivityInContext>
            <Activity id="b1c"/>
        </ActivityInContext>
    </NavigationDivision>
    <NavigationDivision PEDivRef="b2">
        <NavigationDivision PEDivRef="c3">
            <ActivityInContext>
                <Activity id="c3a"/>
            </ActivityInContext>
        </NavigationDivision>
        <NavigationDivision PEDivRef="c4">
            <ActivityInContext>
                <Activity id="c4a"/>
            </ActivityInContext>
        </NavigationDivision>
        <ActivityInContext>
            <Activity id="b2a"/>
        </ActivityInContext>
        <ActivityInContext>
            <Activity id="b2b"/>
        </ActivityInContext>
        <ActivityInContext>
            <Activity id="b2c"/>
        </ActivityInContext>
    </NavigationDivision>
    <NavigationDivision PEDivRef="b3">
        <NavigationDivision PEDivRef="c5">
            <ActivityInContext>
                <Activity id="c5a"/>
            </ActivityInContext>
        </NavigationDivision>
        <NavigationDivision PEDivRef="c6">
            <ActivityInContext>
                <Activity id="c6a"/>
            </ActivityInContext>
        </NavigationDivision>
        <ActivityInContext>
            <Activity id="b3a"/>
        </ActivityInContext>
        <ActivityInContext>
            <Activity id="b3b"/>
        </ActivityInContext>
        <ActivityInContext>
            <Activity id="b3c"/>
        </ActivityInContext>
    </NavigationDivision>
    <ActivityInContext>
        <Activity id="a1a"/>
    </ActivityInContext>
</NavigationDivision>

So, we can have multiple levels of navigation, and each level can have activities. This is a textbook table of contents. So each NavigationDivision level drills down one level further - a1 is Unit 1, b1 is Chapter 1, and c1 is Lesson 1. So, the activity labelled c2b is Unit 1, Chapter 1, Lesson 1, Activity 2. Activity c3a is Unit 1, Chapter 2, Lesson 1, Activity 1.

What I need to do is number the activites within their *immediate ancestor* NavigationDivision. So, for example, c1a would be 1, because it's the only Activity within that immediate NavigationDivision. In contrast, b1a, b1b, and b1c should be numbered 1, 2, and 3 because their parent ActivityInContext elements are siblings within the immediate b1 NavigationDivision. The closest I've come to the correct numbering is using <xsl:number level="any" from="NavigationDivision" />, but it's off in one place, counting b1 as a number 2, instead of 1. This is all (possibly) complicated by the fact that I'm using a for-all to process the activities, rather than a template match. This is the output I'm getting. The generated number is in blue; the number it *should be* is in red (for numbers that are generated incorrectly; the correct ones I've left alone).

Any ideas? I'm learning on the job here, and haven't run into anything like this before.
