How to select tag at specific tree hierarchy in XSLT?

I'm working with XSLT. For one of my requirement I need to catch the tag <random-text:apple>/<random-text:colour>

The thing is my XSLT version is 1.0, so I don't have the full regex support.

Let me give a simple example to illustrate the problem statement:

sample.xml:

<Fruits>
  <random-text:apple>
    <random-text:colour>RED</random-text:colour>
    <random-text:shape>ROUND</random-text:shape>
  </random-text:apple>
  <random-text:round-fruits>
    <random-text:apple>
      <random-text:colour>RED</random-text:colour>
    </random-text:apple>
  </random-text:round-fruits>
</Fruits>

So in the sample.xml, I want to catch <random-text:apple>/<random-text:colour> tag but I want to avoid the same tag in other tree hierarchy like <random-text:round-fruits>/<random-text:apple>/<random-text:colour>

I tried something like this: "/*[contains(name(), 'apple')]/*[contains(name(), 'colour')]" but as you can suspect, it is catching the /apple/colour element in all the tree hierarchy levels.

So, I want to ask:

  1. Is it possible to apply wildcards like */apple/colour to get the desired behaviour in XSL 1.0?
  2. If yes, please suggest

UPDATE: Sorry, I forgot to mention earlier that the random-text is properly defined but I have to do it for many such xml files, so I want something like: <any-namespace:apple>/<any-namespace:colour> element

Perhaps I am missing the point here, because this seems like a trivial problem. The expression:

/Fruits/random-text:apple/random-text:colour

will select the random-text:colour element in the random-text:apple branch, and exclude the other random-text:colour element in the random-text:round-fruits branch.

This is assuming your XML has a proper namespace declaration for the random-text prefix and that this declaration is repeated in your stylesheet.

That is not a healthy situation. Namespaces are part of the XML schema - and a stylesheet should be written for a specific schema.

Still, you could do:

/Fruits/*[local-name()='apple']/*[local-name()='colour']
