XSLT Transformation with match

Question

I have the following xml and I'm writing a XSLT to transform it:

<callop>
    <con>unit</con>
    <var>u</var>
    <var>v</var>
</callop>

The problem is that if <callop> is inside <is> then it should be a <nano> element and <con> becomes <Fun> but otherwise it's an <Atom> and <con> becomes a <Rel> .

How is this possible. Do I have to go and check what the parent node is?

Answer 1

You can handle this pretty easily by just specifying your templates with the full path. The more specific template match will take precedence, so there shouldn't be any issues.

<xsl:template match="is/callop">
   <nano>
     ...
...

<xsl:template match="callop">
   <Atom>
     ...
...
