Today I hope to solve this by myself but I failed... 😖

This time I articulated data.xml in order to have a voice where I could extract the header's name, and I made this document:

data.xml

<data>
  <category head="SPECIES">
    <animals title="MAMMALS">
      <item>Baby Dog</item>
      <item>Baby Cat</item>
      <item>Baby Horse</item>
      <item>Mommy Dog</item>
      <item>Mommy Cat</item>
      <item>Mommy Horse</item>
      <item>Daddy Dog</item>
      <item>Daddy Cat</item>
      <item>Daddy Horse</item> 
    </animals>
    <animals title="BIRDS" new="true">
      <item>Baby Eagle</item>
      <item>Baby Flamenco</item>
      <item>Baby Vultur</item>
      <item>Mommy Eagle</item>
      <item>Mommy Flamenco</item>
      <item>Mommy Vultur</item>
      <item>Daddy Eagle</item>
      <item>Daddy Flamenco</item>
      <item>Daddy Vultur</item>
    </animals>
    <animals title="FISHES">
      <item>Baby Shark</item>
      <item>Baby Betta</item>
      <item>Baby Tuna</item>
      <item>Mommy Shark</item>
      <item>Mommy Betta</item>
      <item>Mommy Tuna</item>
      <item>Daddy Shark</item>
      <item>Daddy Betta</item>
      <item>Daddy Tuna</item>
    </animals>
    <animals title="REPTILES"  new="true">
      <item>Baby Lizard</item>
      <item>Baby Turtle</item>
      <item>Baby Crocodile</item>
      <item>Mommy Lizard</item>
      <item>Mommy Turtle</item>
      <item>Mommy Crocodile</item>
      <item>Daddy Lizard</item>
      <item>Daddy Turtle</item>
      <item>Daddy Crocodile</item>
    </animals>
    <animals title="AMPHIBIANS">
      <item>Baby Frog</item>
      <item>Baby Toad</item>
      <item>Baby Salamander</item>
      <item>Mommy Frog</item>
      <item>Mommy Toad</item>
      <item>Mommy Salamander</item>
      <item>Daddy Frog</item>
      <item>Daddy Toad</item>
      <item>Daddy Salamander</item>
    </animals>
    <animals title="INSECTS" new="true">
      <item>Baby Ladybug</item>
      <item>Baby Spider</item>
      <item>Baby Dragonfly</item>
      <item>Mommy Ladybug</item>
      <item>Mommy Spider</item>
      <item>Mommy Dragonfly</item>
      <item>Daddy Ladybug</item>
      <item>Daddy Spider</item>
      <item>Daddy Dragonfly</item>
    </animals>
  </category>
</data>

Then I tried to create headers and footers with areas but I didn't work out cause those requires unit grids, then I simply put this textblock before the , and it worked although not sure it was the right method:

   <!-- HEADER -->

      <PlaceObject allocate="no" column="12.5mm" row="16mm"  frame="solid" framecolor="green" >
	<Table width="185mm" height="2cm" fontfamily="tito" stretch="max">
	  <Tr align="center">
	    <Td>
	      <Paragraph>
		<Value>HEADER</Value>
	      </Paragraph>
	    </Td>
	  </Tr>
	</Table>
      </PlaceObject>

    <!-- FOOTER -->

      <PlaceObject allocate="no" column="12.5mm" row="260mm"  frame="solid" framecolor="green" >
	<Table width="185mm" height="2cm" fontfamily="tito" stretch="max">
	  <Tr align="center">
	    <Td>
	      <Paragraph>
		<Value>FOOTER</Value>
	      </Paragraph>
	    </Td>
	  </Tr>
	</Table>
      </PlaceObject>

Then I tried to display the value head from the <category> tag but it didn't work out, plus I moved everything between ` ... as it is suggested on the manual. To conclude with the pebcaks I tried to process all the nodes using this semantic:

 <Record element="data">
    <ProcessNode select="*" />
  </Record>

However it didn't work out as well, eventually I was really creative using all the combinations but the right ones. This last version with the header and footer between <Pagetype> ... </Pagetype> return errors, the basic version shows the header and footer but doesn't populate the page, this means that I wasn't able to make sp recording the right data...

Here layout.xml

Perhaps eventually I will be able to understand better how it works... Thanks in advance for helping me with this! 🙏

Just a first small part of the answer, I don't know how much time I have now ;-)

<AtPageCreation>
  <PlaceObject allocate="no" column="12.5mm" row="16mm"  frame="solid" framecolor="green" >

There is a problem here, you cannot access attributes (@head) in the page definition, since there is no "current node" when the page is created (the cursor in the data can be anywhere and @head does not know where it should look for the attribute).

So you have to define a variable and use it in the head:

<Record element="category">
    <SetVariable variable="head" select="@head"/>

and

    <Pagetype name="page" test="true()">
        <Margin left="12.5mm" right="12.5mm" top="25mm" bottom="25mm" …

(you see the $head there?)

More later....

Thank you very much, perhaps I overthought, I am going to focus on replicate a real section of our catalog. I am too much behind my schedule, and next Monday I have the first meeting about our biggest catalog and nothing to show up about speedata... 🤦‍♂️

Since you have the animals element as a child element in category, you need to access the animals node by using <ForAll> or <ProcessNode>.

snippet from layout.xml:

    <Record element="category">
        <SetVariable variable="head" select="@head" />
        <!-- UNIT BLOCK -->
        <ForAll select="animals">
            <Group name="unit">
                <Grid width="1cm" height="12pt" />
                <Contents>
...
                </Contents>
            </Group>

            <!-- CALL THE UNIT BLOCK -->
            <PlaceObject groupname="unit" />
        </ForAll>

    </Record>

Thank you very much, I will try to make this code working. But I need to start using real products and I am not authorized to disclose such information publicly, can I reach you out by email for the next iterations?

I think I am almost there to make my presentation, on my todo list I am still need to:

Import each entry as external XML organized into data.xml (it will be a couple of family products)
Create a TOC
Create a products' index
CSS and stylish, but I don't need to be "perfect" for this.

Thanks,
C.
