 <xsl:variable name="dynamicPath"

i.e. $dynamicPath is a string containing '/document/section/keep/pear'

You are not showing what I would call "a dynamic XPath".  Consider:

         <xsl:variable name="dynamicPath"
                      select="/document/section/keep/pear" />
         <xsl:variable name="textContent" select="$dynamicPath/text()" />

I've modified the second instruction above, such that the node-set variable 
named $dynamicPath, which includes the nodes selected by your XPath 
expression in the first insturction, is used to address all the text nodes 
from each.

It is very acceptable to begin an XPath expression with a reference to a 
node-set variable.

What did you mean by "dynamic"?
