Case test with nodes (if a node exists...)

[Cicorione]

Hi @pgundlach

I am preparing a demo for my workplace, but I got stuck here, I want to create a switch case if Cellular or Mobile are available, I mean if the these nodes exist, but I am doing something wrong and I haven't find a solution yet.

Thanks in advance! 🙏

You can use not(empty(mobile)) to check if there is an element named mobile:

<Paragraph fontfamily="regular">
  <Value>T </Value>
  <Value select="telephone" />
  <Switch>
    <Case test="not(empty(mobile))">
      <Value>&#x2002;</Value>
      <Value>C </Value>
      <Value select="mobile" />
    </Case>
    <Otherwise>
      <Message select="'not defined'" />
    </Otherwise>
  </Switch>
</Paragraph>

BTW: due to a not-changeable design decision, you need to use html="off" on the address element:

<Paragraph fontfamily="regular" html="off">
  <Value select="address" />
</Paragraph>

This would otherwise be interpreted as the address HTML tag and typeset in italic.

Thank you Patrick, this is going to be the first part of the demo, the second part would be to use Publisher to impose the business cards on a letter size, I have figured out something but not sure if it is going to work... 🤔

EDIT

It worked, it took me enough trials-and-errors to understand how to convert absolute measurement in relative into a group and how to laid out it properly into a grid, but I got it. 👍

Hi Patrick,

How can I adapt this:

<Case test="not(empty(mobile))">

to check if an attribute is empty?

This is not working:

<Case test="not(empty(@attribute))">

Thanks... 🙏

[Cicorione]

Found using Duck.ai...

<Case test="string-length(node/@attribute) = 0">

p.s. it didn't suggest the right syntax but I learned about string-lenght

[pgundlach]

empty() checks if a node is present, for example an attribute node. If it is possibly present, you can use string(@attr) = '' to check if it is empty or non existent. Or use string-length() as you write.

Thank you! Xpath operations are very powerful but still obscure to me... 😅
