Variables in data.xml?

[Cicorione]

Hi @pgundlach

I'd like to define an accent colors but it should be defined inside the parent node:

<section secname="SEC01"  accent="MyColors">
	<subsection subsecname="SubSec01">
		<product title="00">
			<item>DUMMY</item>
			<item>DUMMY</item>
			<item>DUMMY</item>
   			<extra>DUMMY DUMMY DUMMY</extra>
   			<extra>DUMMY DUMMY DUMMY DUMMY </extra>
   			<extra>DUMMY DUMMY DUMMY DUMMY DUMMY</extra>
   			<img file="sample.pdf"/>
		</product>
		[...]
		<product title="20">
			<item>DUMMY</item>
			<item>DUMMY</item>
			<item>DUMMY</item>
   			<extra>DUMMY DUMMY DUMMY</extra>
   			<extra>DUMMY DUMMY DUMMY DUMMY </extra>
   			<extra>DUMMY DUMMY DUMMY DUMMY DUMMY</extra>
   			<img file="sample.pdf"/>
		</product>
	</subsection>
	[...]
</section>

However since the code I am running uses this syntax:

<Record element="subsection">
	<SetVariable variable="subsecname" select="@subsecname" />
	<SetVariable variable="accent" select="@accent" />
	[...]
	<ForAll select="product">
		[...]
		<ForAll select="extra">
			<PlaceObject column="1">
				<Frame backgroundcolor="{$accent}">
                	</PlaceObject>
		</ForAll>
		[...]
	</ForAll>
</Recod>

The "accent" value is not taken, but if I move it in the subsection node, the value is taken properly:

<section secname="SEC01"  xmlns:xi="http://www.w3.org/2001/XInclude">
	<img file="SectionIMG.jpg" />
	<subsection subsecname="SubSec01" accent="MyColors">
		<product title="00">
			<item>DUMMY</item>
			<item>DUMMY</item>
			<item>DUMMY</item>
   			<extra>DUMMY DUMMY DUMMY</extra>
   			<extra>DUMMY DUMMY DUMMY DUMMY </extra>
   			<extra>DUMMY DUMMY DUMMY DUMMY DUMMY</extra>
   			<img file="sample.pdf"/>
		</product>
		[...]
		<product title="20">
			<item>DUMMY</item>
			<item>DUMMY</item>
			<item>DUMMY</item>
   			<extra>DUMMY DUMMY DUMMY</extra>
   			<extra>DUMMY DUMMY DUMMY DUMMY </extra>
   			<extra>DUMMY DUMMY DUMMY DUMMY DUMMY</extra>
   			<img file="sample.pdf"/>
		</product>
	</subsection>
		<subsection subsecname="SubSec02" accent="MyColors">
		<product title="00">
			<item>DUMMY</item>
			<item>DUMMY</item>
			<item>DUMMY</item>
   			<extra>DUMMY DUMMY DUMMY</extra>
   			<extra>DUMMY DUMMY DUMMY DUMMY </extra>
   			<extra>DUMMY DUMMY DUMMY DUMMY DUMMY</extra>
   			<img file="sample.pdf"/>
		</product>
		[...]
		<product title="20">
			<item>DUMMY</item>
			<item>DUMMY</item>
			<item>DUMMY</item>
   			<extra>DUMMY DUMMY DUMMY</extra>
   			<extra>DUMMY DUMMY DUMMY DUMMY </extra>
   			<extra>DUMMY DUMMY DUMMY DUMMY DUMMY</extra>
   			<img file="sample.pdf"/>
		</product>
	</subsection>
	[...]
</section>

Unfortunately there isn't any advantage to assign the accent attribute to each subsection, unless I can define somewhere in this document a variable $MyColors.

Is that possible in the data xml assign a variable only for sake to avoid typing it every time?

Thanks! 🙏

You have two options:

1. within <Record element="section"> you can define the color (similar to accessing the img node): <SetVariable variable="accent" select="img/@accent" />

or

2. use the new XPath parser lxml (see https://doc.speedata.de/publisher/en/lxpath/#ch-lxpath) and use

<Record element="subsection">
	<SetVariable variable="accent" select="../@accent" />
...

( add ../ to the attribute definition to select the parent node).

Hi patrick, my fault!

To simplify the code I put the variable in the wrong place, but I guess it is the same:

<section secname="SEC01" accent="MyColors">

Thanks! 🙏

Solution 1. never worked; but solution 2. is not working either...

<Record element="subsection">
	<SetVariable variable="subsecname" select="@subsecname" />
	
        <!-- Me becoming desperate -->
                 
        <SetVariable variable="accent" select="section/@accent" />        
        <SetVariable variable="accent" select="/section/@accent" />        
        <SetVariable variable="accent" select="../@accent" />
        <SetVariable variable="accent" select="../../@accent" />
        <SetVariable variable="accent" select="../../../@accent" />

        <!-- Still desperate -->

	[...]

	<ForAll select="product">
		[...]
		<ForAll select="extra">
			<PlaceObject column="1">
				<Frame backgroundcolor="{$accent}">
                	</PlaceObject>
		</ForAll>
		[...]
	</ForAll>
</Recod>

🤦‍♂️

Solution 2 will work with the next version of the speedata Publisher (not yet available)

Solution 1 will be <SetVariable variable="accent" select="@accent" /> in <Record element="section">

With the last commits you made now is working solution 1. 🤷‍♂️

Sweet! 👍
