Re: Referencing value of non-sibling node

Hi Kim,

>From what I can tell, each <mt> is associated with a particular <r>
based on its position, so the first <mt> in a <mi> is related to the
first <r> within the <mv> of that <mi>, the second <mt> with the
second <r> within the <mv> of the <mi> and so on. Is that accurate?

If so, then in your template matching the <mt> element, you have to
first find out the index of the <mt> within the <mi>. Now, you're
actually applying templates to these <mt> elements in order, so this
is quite easy -- all you have to do is store the position() of the
current <mt> element in a variable:

  <xsl:variable name="index" select="position()" />

and then use that index to find the <r> element within the <mt>
element's parent <mi> element's child <mv> element with the same
position:

  <xsl:value-of select="parent::mi/mv/r[$index]" />

If that isn't what you were after, give us a more detailed description
of what the "corresponding <r>" means.

Cheers,

Jeni
